Generating Green Energy: Sustainable Packaging Design Tips

With “sustainability” being a major buzzword it is not surprising that packaging comes under scrutiny to ensure it satisfies those who are aiming to improve the environment we live in and promote “green” living. Manufacturers are facing strong pressure to ensure packaging meets the sustainability criteria at all levels of the process from government policies and consumer requirements as well as others. It is not a simple issue as to comply with “green” standards every aspect of the packaging must be environmentally friendly.

While in an ideal world packaging would be entirely “green” it is just not possible for this to happen at this time. It is possible that in the future all packaging could become sustainable, but in the mean time, it is a process of making incremental improvements when and where we can, working our way towards a product that eventually will have less and less impact on the environment.

Whether packaging materials consist of plastic, paper, glass or aluminum each has its pros and cons. None of them can be classed as being completely good or completely bad. In that respect, tradeoffs are a necessity as true sustainability is being worked towards.
While the impact packaging has on the environment should never be trivialized it is important to understand that it makes up only 10% of the carbon footprint of a product, with the largest portion being created by manufacturing of the raw product, and consumer use. All that being said there is a fine balance between being as “green” as possible and still fulfilling its purpose of protecting the product and enticing customers to purchase. If the product doesn’t perform as intended any attempts to make it sustainable will have been in vain as the effort will have been wasted.

Explaining Plumbing Isolation Valves

Shutting off the water at the main stopcock will stop the water from coming into the storage tank. It will not top hot or cold water that is already in the tank from getting to the appliances such as the bath or the sink. It will take some time for the reservoir to be drained. Turing off the water to the tank will be easy if the washer needs to be replaced or other parts of the system need to be fixed. If this water cannot be turned off the tank will need to be drained.

Depending on how old the water system is, the valves along the pipe work may or may not be able to be worked on.

General Load Bank Testing Basics and Methods

A load bank is a self-contained unit which is used to apply controlled load on a power system. Ideally, load banking is a system which is used to determine the maximum backup power performance of a system. This technique should be performed regularly to make sure that the performance system is running efficiently.

Load banking can be used to:

• Verify system operation
• Commissioning and maintenance of a system
• Certify system capacity

Why perform a load bank test?

This test is carried out to ensure that the portable back-up generator is running to its full potential to make sure that it an be able to provide enough power when needed. Since emergency generators are sized so that they can be able to accommodate full start-up load of the facility they are supposed to supply with power, most emergency generators are sized above the normal operating load if they don’t have load management system. This serves as a guarantee that the generator will be able to produce enough energy for the whole facility.

Most generators are sized to about 30% or more of kW rating of a facility. This is important to regulate the surge of the building, as well as the equipment, start up load. However, this challenges diesel powered generators because it can develop conditions such as wet stacking and carbon build up (in piston rings, turbo chargers, injector nozzles, combustion chambers and exhaust piping).

What is wet stacking?

Wet stacking is the unburnt fuel which usually accumulates in diesel exhaust. Usually, wet stacking can be detected after warm up as a black seepage around the exhaust connections or as a continuous black exhaust. To avoid wet stacking, exhaust gas must be maintained at a temperature of about 275⁰ Fahrenheit or else it would lead to exhaust pollution. Load banking plays an important role in the conservation of the environment because it minimizes exhaust pollution when carried out properly and regularly.

For a generator load bank to operate at peak efficiency, its engine must be able to provide the right fuel-air ratio to be able to maintain the right temperature which would help in complete burning of fuel. Wet stacking is very common when diesel engines operate for a long period with little or no load testing procedures. However, due to exhaust pollution and wet stacking problem, EPA has set requirements which have resulted in diesel engine design improvements to minimize wet stacking.

Additionally, the use of electronic controls has increased diesel engine performance and thereby reducing the amount of unburnt fuel from these engines.

Load bank testing equipment for standby applications should per performed annually for a minimum of about two hours to make sure that the system is working optimally. (LEARN MORE at www.foxfab.com/load-bank-testing-how-does-it-work/

)

If you are commissioning an emergency power system, you are supposed to have a load bank testing to help you:

• Ensure proper installation
• Ensure adequate cooling to ambient temperatures
• Determine whether there is sufficient fuel delivery
• Have proper load transfer

Load banking process

a) Logistics

It is important to be logical when carrying out load banking because the load bank emits heat. This heat can destroy plants, trees or even discolor the paint of objects found too close or even on the path of exhaust air produced. Also, to facilitate cooling, the load bank should be in a place

b) You are supposed to disable the emergency switch gear to avoid accidental transfer to a facility load.

c) You should confirm that the cable size to be used can be able to carry the full Amp load between the transfer switch and generator breaker depending on the rating given by the manufacturer to avoid overloading the cable.

d) The cables used should carry only the rated load with additional cable length leading to an increase in cable size.

e) To avoid inconveniencies, the facility manager should be notified of the start time and the estimated completion time depending on how long load bank testing will take.

f) For safety, all cables should have color codes before installation to ease identification. Additionally, during load bank testing, you should ascertain that all cables used have proper insulation, correct phasing, and secure termination.

g) After using the master switch to ‘block’ the load, you should start your generator and then allow it to run for 5-10 minutes to warm up.

h) Later, you should apply load stepwise allowing about 15-30 minutes between the steps.

i) While being very careful and ready to remove the load in case you detect problems, monitor the engine closely for leaks, temperature, and oil pressure.

j) You are then required to block load in each step while still recording the ability of the generator to pick up the load in one step by switching the master switch. After blocking the load, you are required to measure the exhaust temperature and then compare it with the recommendations given by the manufacturer for both the engine and exhaust filter if they are installed.

k) Finally, give the generator a 30 minute cool down period without a load.

Planning

Before testing the generator, you should review the worst case scenarios with your client since there could be potential risks of failure during testing. Most generators have not been tested to their full capacity since they were last tested after their manufacture and hence load bank testing could result in them breaking down during testing. Ideally, the older the generator, the higher the risk of breaking down. However, the results given from load banking shows the level of neglect or under use of the generator and hence it is important to carry out the test.

The power supply to the facility should be disconnected from the generator while testing to avoid overloading the generator. Additionally, the staff should be notified in advance to prepare in case of a blackout, and the facility runs life support machines which need to run all through. Therefore, backup generators should be stand by to address the situation. Also, testing should be scheduled to the most favorable time of the day, week or month when the situation could be managed easily.

While planning for load bank testing, you should also consider local Environmental Protection Regulations to avoid heavy fines for failing to follow these laws.

Methods of load bank testing

Resistive and reactive testing are the two methods which are used in load bank testing.

• The resistive method is the most common method of the two, and it entails measuring kW and not kVA at the rated power factor. The method is very effective in testing the cooling system, exhaust system and fuel delivery system of engines.• Reactive testing is generator specific, and it is carried out in the factory to test Observations
• If the exhaust is smoke-free during testing, the engine should be repaired. A lot of smoke is caused by rings which have not been set properly, bad fuel or a faulty fuel pump
• If your generator’s temperatures are not within the recommended range, your cooling system, thermostat or water pump could be faulty and needs fixing
• If generator oil falls below the recommended range, the oil pump may need some fixing because it could be having a problem.

Alternatively, the low pressure could indicate an excessive engine wear meaning that the engine should be overhauled.

Documentation

In documentation, a digital recorder should be connected to the chart frequency, voltage and amperage during one-second sampling. The information recorded should then be downloaded to a performance report. Also, the engine oil pressure and temperature of the nameplate rating of the generator should be documented at 25, 50, 75 and 100 percentages.

Load bank testing should be considered as a necessity to get optimum performance from your generator. If you are a maintenance provider, you should recommend load bank testing to your client since it is essential to know how their generators are performing.

How Much Does A Plumber Cost?

No one likes to call a plumber, but in some cases it is necessary. Like when you are doing will make the cost higher in the end. They are professionals because they know what they are doing. Rather you need everyday maintenance, major renovation, or an emergency that is getting serious fast it is worth the cost to have it done right the first time.

How much does it all cost?

The cost of a plumber is subject to a few factors. Based on where you are located right now the price may change. Even with this, an estimate is still very possible. This article will show you what to expect to pay when calling a plumber. It will also cover what type of jobs plumbers get trained to help you with.

What type of jobs can a plumber do?

An integral part of every home is a plumber. So you will have to call them sometimes.

Plumbers do a variety of tasks including:

-Toilet Repair
-Toilet Installation
-Repairing taps and burst water pipes
-Finding and fixing leaks in water and gas systems
-Home renovation projects
-Installing and repairing hot water systems
-Installing solar hot water systems
-Replacing old plumbing-Installing and connecting accessories such as water filters
-Installing guttering
-Installing new drains, repairing drains and unblocking drains

Some jobs may need more training. These jobs may call for the plumber to have a condition on their license.These jobs include:

-Fire protection services
-Urban irrigation
-Sanitary drainage

Does my plumber need to have their licensed?Short answer, Yes. To advertise their services or even work in your home they need to have a license. This rule applies nationwide.

Make sure you make the distinction between a licensed contractor, who has been trained to oversee bigger projects. They are responsible for managing plumbers that hold a trades person certificate, whose work needs to receive inspection from an official plumbing contractor. All that is required for most jobs is a standard license. When you need work done on any gas item, be sure to verify the plumber also has a license for gas fitting or a valid endorsement.

Plumbers must also give you a “compliance certificate.” This will confirm that any work done meets the mandatory stipulations.

What is A Master Plumber?

You may have seen a few plumbers that advertise as Master Plumbers. What does that mean? This means the person is a Member of a Master Plumbers Association that is state-based. So that they uphold the highest standards and give a superior service, they have access to the latest in industry advice and expertise.
For example, admonishes getting the cheapest quote. Instead get at least three quotes of work that needs to be performed.

Is it better to hire a Master Plumber?

They have the same license as any other plumber, but they are better informed.

Hiring a Plumber

It helps to know what questions to ask, so you make sure you find the right plumber for the job. Some questions you should ask courtesy of a Red Deer Plumber include:

-Do you have your plumbing license?
-Do you have the proper insurance to work inside of my home?
-Will you be able to provide me with a written quote?
-Do you have a list or references that I can follow up on?
-It does not matter how small the project is, always make sure you ask for a full itemized quote that includes the cost of all materials.
-Make sure you can compare the price with the level of service by getting at least three quotes before you commit to anything
.-The average cost for services from a plumber.

So how much will a plumber cost you?

Usually, plumbers will charge something called a call-out fee.Essentially it is what you pay for a house call. After that, they charge a certain amount per hour until they complete the job.

A call-out fee usually cost between $ 60 to $100.

Depending on the plumber hourly rate can be anywhere from $100 to $150.What your plumber charges could be a mix of anything from the level of skill they have to what area you currently live in. For example, someone that is has a Master Plumber status will probably charge more. While your plumber will more than likely have a specific amount, they charge for their services.

Many plumbers go as far as offering a service for 24-hour emergency plumbing. They recognize that many plumbing concerns happen outside of the 9-5 work window! Even though most plumbers you encounter will charge more for calls at odd hours, some will maintain their regular per hour rate.

Though this may differ based on where you live, expect to pay about:

-$60 to $140 fixing your tap that drips or your toilet that leaks
-$80 to $250 to give you a new shower head, basin taps, and to replace and then fit bath
-$160 to $550 to install any toilet, bath, basin, and sink.
-$1,200 to $4.500 for your hot water service replacement
-$3,500 to 20,000 for them to install a water system with solar heat, this varies based on the size and complexity of the system
-5,000 to 20,00 for replacement of the entire drainage system
-$6000 to $12,000 when you have your whole house re-plumbed, depending on the necessary supplies and skills.

Remember after the plumbing is done allow some extra funds in the budget for any other necessary work. This may include painting, tiling, or even rendering after the job is all done.

Getting and comparing quotes from plumbers

When you compare any quotes, make sure you have a complete understanding of what is included in the quote and what is not.You will see the cost of materials on some quotes while others leave it off.
Sometimes the plumbing cost may add up to more than they initially thought. Make sure you ask them to tell you before any work begins that was not initially discussed.

Always remember, with most plumbers if you keep them waiting they are likely to charge you more.Make sure before you jump and choose the cheapest quote you review all options. This will ensure that you pick a plumber that is not only in line with your cost but also fit your specific needs.

Make sure you get quotes from local contractors in your area. This will give you the best understanding of where the markets currently are.

Look at The Value of Load Bank Testing

Load bank tests help facility managers determine if their load bank generators will meet their nameplate rating. This is ideal for managers that want to avoid the problem of having a defective generator on the premises during a power outage. It is imperative to point out that the absence of regular load bank testing may lead to having generator failure during a real emergency. This is the primary reason why load bank testing plays a vital role in the generator maintenance program.

Wet stacking takes place when unburned fuel builds up in the exhaust system. This typically occurs when the generator operates at less than a full load. This makes it tough for the generator to produce enough heat to burn off the excess fuel. The unburned accumulation of fuel will cause severe damage to the engine valves, exhaust system, and fuel injectors. The engine will not run at its optimum level if the proper mixture of fuel and air is not maintained.

When it comes to wet stacking, carbon buildup takes place when the generator’s engine does not produce enough heat to eliminate the buildup. The piston rings within the engine will malfunction if the carbon buildup is not monitored. Research shows that the superheated fuel/air mixture travels past the rings and damages the sides of the pistons.

Load Bank Basics

A load bank connects a durable controllable electrical load to the generator. The load bank can be permanent or portable. It is also suitable for an AC or DC charge. Many load bank generators come with an internal fan that keeps the resistive elements cool and transports the high-temperature air away from the unit. The load bank unit must be positioned away from the combustible material to make certain that it does not overheat.

There are two main types of load bank testing methods (resistive and reactive). Resistive is the most popular field testing method because it includes the entire kW rating of the generator and the primary engine systems. Reactive testing normally takes place at the onset factory to test kVA ratings.

Load Bank Testing Schedule

Generators should go from a cold start to a full load within a matter of moments. The generator must be exercised at 30% load for at least thirty minutes each month. This monthly test will keep the internal engine parts lubricated, minimize oxidation of electrical contacts, uses fuel before it deteriorates, and helps the engine start properly.

An annual load bank test should only take place when the generator’s kW capacity is at 100%. Experts state that the test should last for at least one hour. The load should be increased gradually during the testing period.

Testing Tips

Load bank testing can detect problems in a controlled situation with ease. Let’s take a quick look at a few tips that can help you discover problems with your generator.

-Be ready for unexpected results or system failure during a load bank test.

-Keep a backup generator on the premises if you are running a healthcare facility or a business that cannot afford a power outage.

-Test the generator during non-peak hours if you are running a facility that can afford a power outage for a short period.

-Make certain that the generator is disconnected from the facility.

-Check for visible leaks, loose connections, and abnormal performance.

-A good generator will produce black exhaust during the testing period. This is a sign that the engine is doing a great job of eliminating the carbon buildup and the fuel in the exhaust system. However, the engine may need repairs if the smoke does not clear before the testing period is completed.

High cooling system temperature and low oil pressure can take place during the testing period. A faulty thermostat or blockages are the culprits for high temperature. Low oil pressure can occur when the oil pump needs to be repaired.

Conclusion

It is vital for you to keep a dependable load bank generators on the premises. Load bank testing should always be a part of the regular generator maintenance schedule. This ensures that the generator will run at its optimum level. Testing also helps the operator find out if the onset can run at its full kW level. Following the tips above can help you maintain your generator with ease.
