What is the shelf life of fuel for diesel generator sets and what should I pay attention to when storing it?

June 16, 2022
Diesel generator set is a kind of power machinery that uses diesel as fuel and diesel engine as the prime mover to drive the generator to generate electricity, it has high requirements for fuel, using expired or poor quality fuel will reduce the power generation effect and service life of the set, so users must understand the shelf life of diesel generator set fuel and the precautions when storing it.
How long can the fuel of diesel generator set be stored?
If you ask different people this question, you may get different answers. This is because the storage life of any fuel depends on the conditions in which it is stored. Under ideal conditions, diesel fuel can be stored for 6 to 12 months. If you want to extend its shelf life beyond twelve months, even under optimal conditions, it needs to be treated with fuel stabilizers and biocides. Twelve months is the longest reasonable storage estimate if the fuel cannot be kept at 21°C and below all the time.
Diesel generator sets have certain requirements for fuel, the fuel used must meet the requirements of CB252-81, when the ambient temperature is 5-24℃, 0#, -10# light diesel fuel can be used, 10# light diesel fuel can be used in southern areas, -20#, -35# light diesel fuel can be used in northern winter alpine areas, all diesel fuel should be precipitated for 72 hours before use, the minimum precipitation time should not be less than 24 hours, in order to ensure that the diesel can have a long shelf life, users should pay attention to the following matters when storing: 1.
1, fuel tank made of stainless steel or steel plate, do not paint or galvanize the inside of the fuel tank, because they will chemically react with diesel fuel, resulting in impurities that may cause damage to the diesel generator set and reduce the quality, cleanliness and combustion efficiency of diesel fuel.
2, after the placement of the fuel tank, the highest oil level can not be higher than the base of the diesel generator set than its 2.5 meters, such as a large oil depot oil level higher than 2.5 meters, should be added between the large oil depot and diesel generator set day tank, so that the pressure of the direct delivery of oil is not greater than 2.5 meters. Even during the diesel generator set off, do not allow the fuel to rely on gravity, through the oil feed line or injection line into the diesel engine.
3, after each work as much as possible to fill the daily fuel tank so as to prevent the moisture in the tank air from mixing into the fuel.
4、If the fuel tank is placed outdoors, it should be well protected from rain.
5、Whether the fuel tank is placed indoors or outdoors, users should regularly open the tank drain cocks to remove water and sediment.
