The generator base fuel tank is designed to store a large volume of fuel for continuous operation of the generator set. Fuel is supplied through pipelines, and the connection interface should allow easy access for fuel trucks. For safety, the tank must be securely closed and lockable.
The fuel tank should also be equipped with an oil level indicator and an overflow alarm system connected to a liquid level switch to ensure safe and efficient operation.
When an intermediate fuel tank is used, an electric fuel transfer pump must be installed. The pump should be positioned as close as possible to the main storage tank and must have sufficient capacity to ensure reliable fuel transfer.
Fuel storage tanks should be equipped with the following components to ensure proper functionality and maintenance:
1) Isolation devices for cleaning and maintenance, especially when multiple tanks are installed
2) Fuel supply interface for easy connection
3) Breather vent to maintain pressure balance
4) Overflow connection linked to the intermediate tank
5) Inspection port with a diameter of approximately 18 inches
6) Liquid level indicator or oil gauge
7) Supply pipeline located opposite the drainage outlet
8) Filters and bottom (belly) valves where necessary
The oil storage tank should be installed on a solid foundation elevated by at least 50 mm. This elevation helps meet fire protection standards and supports proper heat dissipation through natural convection.
The tank installation must comply with a minimum 4-hour fire resistance requirement to ensure operational safety in case of emergencies.
All above-ground fuel tanks should be enclosed within a protective structure designed to enhance safety and environmental protection.
The structure should meet the following requirements:
1) Adequate size with at least 10% additional capacity space for safety
2) Leak-proof oil collection system installed on the floor
3) Proper drainage channels on walls and floors
4) Manual or electric pumping system for emergency handling
5) Proper grounding of metal components in accordance with local regulations
For underground fuel tanks, the excavation size must allow sufficient space for safe and efficient installation. Care must be taken to avoid damage to the tank’s protective coating during placement.
During the backfilling process, attention should be given to avoid sharp objects such as stones and metal debris, which could damage the tank structure or protective layers.
Proper design, installation, and maintenance of generator fuel tanks are essential for ensuring safe operation, fuel efficiency, and long-term reliability. By following these guidelines, operators can minimize risks, comply with safety standards, and extend the lifespan of fuel storage systems.
