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.

How Well Does Fuel Polishing Work?

To keep a facility or site that stores a lot of fuel running, especially for long periods, facility managers must follow fuel polishing methods. A fuel polisher for diesel tanks successfully removes different contaminants that might be present. These maintenance systems have polishing parts that remove dangerous pollutants in the fuel very well.

Most of the time, a fuel polisher for engines works automatically on a set time. The fuel will flow through many filtration steps in these systems, and each stage will do a different job of polishing it. Here's what the process generally has: 

• Filtering process: A multistage filter system cleans the fuel by removing big things like dirt, rust, and water droplets. 
• Technology for separation: Separators are used to take free water and emulsified water out of the fuel. 
• Controlling microbes: Depending on the use, fuel polishing may include chemicals that stop microbes from growing. 

Signs Your Fuel Needs Polishing

Many things can help you determine whether the fuel you've kept needs to be polished. Protecting energy sources is important, as top fuel quality works best for operational dependability.

1. Duration Of Storage
   Polishing fuel sitting in a tank for a long time can be a good way to keep it clean, even if you don't see any problems right away. This is important, as contaminants can build up over time.
2. Quality Of Fuel
   If you think the fuel isn't very good because of where you bought it or when loaded, fuel filtration and polishing can help it work better.
   
   
3. Maintenance Checks
   Fuel polishing is recommended as a preventative step once a year, especially for essential machines that can't be shut down.
   
   
4. Chemicals Seeping Through an Unsealed Access Port
   If the fuel access port isn't properly sealed, water, dirt, or other objects might enter the fuel source. This pollution can greatly affect the fuel quality and the engine's performance.
   
   
5. Water In The Filters And Separators On Board
   If your internal filters and water separators catch a lot of water, this could be in the fuel tank. In such cases, fuel purification and polishing are needed.
   
   
6. Change The Engine Filter Often
   If your engine filters need to be changed more often than normal, it's probably because contaminants are building up in the fuel. The thick sludge in your filters could be a sign of a much bigger buildup in the tank.
   
   
7. Sludge in the Fuel Tank
   Filters with a lot of sludge are likely to be highly contaminated. If this sludge is not removed immediately, it can block filters, stop fuel flow, and damage engines.
   
   
8. Fuel That Is Cloudy Or Discolored
   Check your fuel visually. Depending on the type and dye, clean fuel usually looks yellow, orange, or red. If the fuel is too cloudy, murky, or thick, it could mean it has been contaminated and needs to be polished.

Summing Up

Using a fuel polisher to improve the quality of your fuel will keep your engines going well and avoid costly repairs or downtime. By checking your system often and finding these problems early, you can keep it running at its best and make it last longer.
