How Fuel Polishing Improves the Efficiency of Diesel Generators?

Unplanned downtime caused by power outages can cost you thousands of dollars, if not more. Businesses, educational institutions, hospital facilities, and residential complexes heavily invest in power backup. It is an excellent step towards enjoying uninterrupted power supply even when the main source is off.
Maintaining the shelf life of a generator ensures a continuous power supply. There are many recommended best practices when it comes to fuel system maintenance. Regular fuel polishing is one such practice that you must be aware of.
Read on to learn more about fuel polishing, its benefits, and how it enhances the shelf life of diesel generators.
What is fuel polishing?
Fuel polishing is a process for cleaning hydrocarbon and oil fuels in storage tanks for future use. The stored fuel goes through a filtration process, extracting contaminants without fuel additives.
Contaminants include microbial growth, sediment, and bacteria whose presence reduces the generator’s efficiency. The fuel polishing process helps reduce the build-up of sludge at the bottom of a diesel fuel tank.
What is a fuel polisher system?
A fuel polishing system is a set of tools that uses filtration systems to clean the fuel. Some generators come with a fuel polishing system, and when this is the case, owners do not need an external fuel polishing service. If a generator does not have fuel polishers, an engineer can be hired by a generator maintenance service provider offering a fuel polishing service.
Today, industrial backup power systems have an attached fuel polishing system that can automatically run. Fuel polishing is an essential generator maintenance process that needs to be conducted at least annually.
Why is diesel fuel polishing needed?
Generators use different fuels. Those that use diesel fuel must store it for a long time, sometimes as long as ten years. However, the fuel may start collecting contaminants within six months of storage. As diesel fuel is used, it can pull in external dirt that settles at the bottom of the tank. Hence, the generators must have their fuel polishing systems.
Diesel fuel generators must follow regular fuel quality tests, followed by fuel polishing, which is a vital pillar of this process. The result is improved fuel quality and uninterrupted fuel supply.
Benefits of filtering fuel tanks
Here is how diesel fuel polishing can expand the shelf-life of generators:
- The fuel storage tank cleaning process prevents sludge and microbial contamination from building up in the fuel tank bottom and on tank walls.
- The fuel polishing system helps maintain fuel quality and clean out contaminants.
- It is equipped with water separators that remove water that has entered the tanks.
Impact on diesel fuel power backup
- Fuel purity increases fuel supply and enables the efficient running of generators. This process increases the time needed to provide backup power systems during a power failure.
- Reduced fuel contamination enables the generator to operate properly. It reduces breakdowns and extends the shelf-life of the generator. Moreover, it has a direct impact on cost savings.
- There is no need to facilitate regular fuel replacement, which is costly.
In conclusion
Generator maintenance is needed for reliable power backup. Fuel polishing is a vital part of this process. Without it, the fuel quality deteriorates over time, affecting the generator's efficiency and longevity. Hence, the generator should have a fuel polishing system.

How to Effectively Clean Diesel Fuel Systems?

One of the common problems with deploying a diesel generator is fuel storage—which presents many challenges over a long time. While you might not be sure to stock up or leave a full tank sitting for an extended period, the contamination issue becomes much greater the longer it is kept. In turn, it may damage your generator and cause a breakdown when you need power for operations.
However, if you plan on storing diesel for a certain time, you can prevent contamination through a process called fuel polishing. Essentially, it removes impurities and reduces the chances of damage occurring. Here's how fuel polishing cleans your diesel fuel tank and why it is needed.
Filtering Diesel Fuel System
One common way of keeping water contamination and debris from forming in stored fuel for diesel engines is through filtration. During this task, diesel passes through progressively narrower filters, trapping suspended solids and letting fluids pass through. This helps in removing debris, sludge, and sediment from the fuel. Some diesel fuel filtration systems also offer the ability to clean water from diesel through absorption.
However, relying on filtration alone may overwhelm the filters. Frequent filter changes are a sign of overworked filters and poor fuel quality.
You must know that diesel fuel filter cleaning is a necessary step but not sufficient by itself. Sticking to a maintenance plan is a better option to avoid frequent fuel filter changes down the line!
What Does Fuel Polishing Treat?
Filtration is just one stage of fuel polishing, a technical cleaning process that removes sediment, water, and microbial contamination from diesel fuel engines.
During this process, the fuel is filtered from the tank through a special process that involves filtration, centrifuges, and coalescers. Advanced filters help capture suspended particles and water separated from diesel by a centrifugal force. Water-blocking filtration media then absorbs if there's any residual water.
Fuel polishing is more thorough than filtration alone in eliminating contaminants and keeping the diesel at industry requirements. For those with generators and backup power sources, this significantly reduces the chance of a breakdown or damage to the machine due to bad fuel.
Not All Fuel Polishing is Equal
While fuel polishing is a better alternative to filtration, it is crucial to note that not all companies that offer polishing services do a complete job. Some do partial filtration when pumping the diesel from the fuel tank, and few do enough to address the existing sludge at the bottom. Others stick a tube in the tank and suck out sludge.
When clean fuel is added to the dirty tank, microbial growth, and water issues return. This causes re-contamination practically before the technician has even left the site. In short, a partial fuel polishing process leads to wasted money and time.
How Often Should Fuel Polishing Take Place?
There are different schools of thought on the fuel polishing process and its frequency. However, most industry experts agree that it is best to do it at least once a year.
Usually, you need to remember that if you have an existing diesel fuel filtration system and utilize underground tanks that are free from water contamination, the need for fuel polishing is limited to just annually. Those with tanks more susceptible to contamination or storing higher amounts of diesel must consult an expert on an appropriate fuel polishing or fuel tank maintenance plan.
