Do you know the types of fuel tanks for diesel generator sets?
June 01, 2022
Diesel generator sets are powered by using the input mechanical energy to start fuel combustion and convert the released energy into electrical energy. Therefore, the user must store fuel so that the diesel generator set can be supplied with fuel in time during a power outage, otherwise the diesel generator set will be Losing its role, we all know that fuel should be stored in specially designed fuel tanks, which are divided into three categories: sub-base fuel tanks, underground storage tanks, and above-ground storage tanks.

Come and find out about the generator manufacturer - Dingbo Electric Power.
1. Sub-base fuel tank
If you need to store less than 3785 liters of fuel, Top Power recommends that you use a sub-base fuel tank. As the name suggests, the sub-base tank is designed to be mounted above ground but below the genset base.
The sub-base tank is rectangular in cross-section and is a double-wall tank. This helps prevent fuel spillage in the event of a leak. Both tanks shall be constructed of heavy gauge welded steel. Some pipes and fittings are connected to the main tank, the important ones are supply and return oil, exhaust port, emergency pressure relief valve and high and low oil level alarms. Tank filling systems must be designed so that they do not overflow during filling and the inlet valve automatically closes when the tank is 95% full. Once installed, the primary tank was tested at 5psig and the secondary tank was tested at 3psig.
2. Underground storage tanks
If you need to store more than 3785 liters of fuel, Tingbo Power recommends that you can choose an underground storage tank or an above-ground storage tank. Underground storage tanks cost more to install but last longer because they are isolated from the environment. Underground storage tanks can be made of fiberglass reinforced plastic. Such tanks are usually ribbed to provide structural strength. Alternatively, underground storage tanks can be made of steel but with appropriate cathodic protection to prevent groundwater corrosion. Likewise, piping from underground storage tanks to generators can be fiberglass reinforced plastic or cathodically protected steel.
Leaks and overflows in underground storage tank systems can be costly and difficult to correct. Such systems must be equipped with spill prevention equipment and procedures. In the worst case, underground storage tanks should be installed to contain spilled or leaked fuel in a limited area. Therefore, the underground area is surrounded by concrete floors and walls. After the underground storage tank is installed in the area, the outer area is filled with sand and gravel.
3. Above-ground oil storage tank
Above-ground oil storage tanks are installed above the ground. Although they are similar in construction to underground storage tanks, the installation procedures for the two types of fuel storage tanks are very different. This is due to different factors that need to be considered in order to minimize the risk. Above-ground storage tanks are a fire hazard with a risk of fire spreading to other nearby facilities. Therefore, these tanks must be installed at a minimum specified distance from other facilities. To control spills and leaks, dikes must be built around above-ground storage tanks. The free volume enclosed by the cofferdam should generally be 110% of the tank volume. Aboveground storage tanks also need to be protected from weather conditions by suitable protective structures.
