Filtering and Cleaning of Diesel Generators Part 1

In all oil and gas supply chains, generators are used for drilling and pump operations in refining and other downstream manufacturers, especially those in remote areas. Although most operators recognize the importance of regular maintenance, in our experience, many operators have not given enough value to use cleaner fuel as much as possible and ensure that the fuel tank itself is free of impurities.

Diesel generators are particularly susceptible to early wear and damage from "dirty" fuel. In addition, due to impurities blocking the fuel filter, limited fuel flow will have a negative impact on the performance of the filter and diesel generator. Users may believe that the new engine is more advanced and can better solve fuel problems. In fact, the opposite is true.

In recent years, technological advancements, including high-pressure injectors and pumps, have made the use of clean fuels more important. In fact, for all engines, especially newer engines, various harmful substances, from condensed water to oxidized particles on the tank, can cause serious problems. In this article, Dingbo Electric will provide some advanced processes and operating procedures to allow operators to maintain the original diesel as much as possible after entering the diesel generator.

Why does diesel degrade and the interaction between fuel and fuel tank?

Diesel fuel can be stored for six months to a year without significant quality degradation, while maintaining cleanliness, coolness, and dryness. However, in frequent use, the fuel stored in the fuel tank will be recycled, causing water, microorganisms, and spoilage.

After the diesel generator draws oil from the fuel tank, it uses a high-pressure fuel pump to enter the nozzle, allowing it to withstand extremely high temperatures and pressures. Fuel that has not been sucked into the nozzle in the engine will return to the fuel tank. As a result, most of the fuel in the tank can be continuously recycled to bear enormous pressure and heat.

This phenomenon can lead to the condensation of asphaltene, a dense molecular substance mainly composed of carbon, which also contains hydrogen, nitrogen, oxygen, and sulfur, as well as small amounts of vanadium and nickel. In short, asphaltene is a viscous, black, and highly viscous petroleum.

Tar - in the form of asphalt - is a good paving material used for roofs and waterproofing coatings, but it is very hard on engines. This type of asphalt will form large blocks and solids over time, making it difficult for diesel generators to burn. They can grow very large and cannot pass through the fuel filter. Instead, sludge blocks the filter.

What makes the situation even more complicated is that the hot fuel returned to the tank increases the temperature of the remaining fuel, causing condensation and turning into water (ultimately algae due to microbial contamination), which dissolves with the fuel. The heating also accelerates the decomposition of fuel. Causing the accumulation of sludge, sludge, and acidic substances. The water and acidity inside the tank can cause corrosion and further exacerbate fuel deterioration.

Most pollutants only temporarily settle to the bottom of the tank. Every time they refuel, they are stirred and may become suspended in the fuel.
