The level of fuel consumption of diesel generator sets is closely related to the cost of use. Many customers will pay more attention to the fuel consumption of diesel generator sets when purchasing, but most customers do not know the size of the fuel consumption of diesel generator sets and the calculation of diesel power generation. The way of the fuel consumption of the generator set, the generator manufacturer Dingbo Electric reminds: the calculation method of the fuel consumption of diesel generator sets is related to the fuel consumption rate and the size of the power load.

Diesel generator sets

The level of fuel consumption of diesel generator sets is closely related to the cost of use. Many customers will pay more attention to the fuel consumption of diesel generator sets when purchasing, but most customers do not know the size of the fuel consumption of diesel generator sets and the calculation of diesel power generation. The method of fuel consumption of the generator set, the generator manufacturer Dingbo Power reminds: the calculation method of fuel consumption of diesel generator sets is related to the fuel consumption rate and the size of the power load: two factors:

1. Fuel consumption rate

Different brands of diesel generator sets have different fuel consumption rates, and the corresponding fuel consumption is different; the approximate fuel consumption of most diesel generator sets is 196g/kw.h---230g/kw.h, the specific Depends on the technical parameters of the diesel engine.

Second, the size of the electrical load, the diesel generator set load is larger, the throttle is larger, the fuel consumption is larger, and vice versa, the relative fuel consumption is smaller when the load is smaller.

In order to facilitate everyone to understand the approximate fuel consumption of the generator set and calculate the use cost of the generator set; Dingbo Power will calculate the approximate reference value of 30kw-500kw for everyone.

3. The specific formula for calculating the fuel consumption of diesel generators is as follows:

One liter of diesel is about 0.84-0.86 kg (1L=0.8-0.85KG).

Most manufacturers of diesel generators use g/kw.h, which means how many grams (g) of oil the generator set consumes per kilowatt (kw) per hour, and then change the unit to liter (L) to be able to Know your hourly gas cost.

The proportion of water and diesel is about 1:0.84-0.86

That is to say, 1L diesel ≈ 0.84-0.86 kg/kg

Diesel generator fuel consumption algorithm/h

Rated power × fuel consumption per hour (g/kw.h) ÷ 0.84 (density kg/L) = fuel consumption

Such as: 220kw diesel generator set fuel consumption 200g/kw.h

That is: 220×0.2(kg)÷0.84=52(L)

The calculated value of the fuel consumption of the generator from 30kw to 500kw is as follows:

30kw diesel generator set fuel consumption = 6.3 kilograms (kg) = 7.8 liters (L)

45kw diesel generator set fuel consumption = 9.45 kilograms (kg) = 11.84 liters (L)

50kw diesel generator set fuel consumption = 10.5 kilograms (kg) = 13.1 liters (L)

75kw diesel generator set fuel consumption = 15.7 kilograms (kg) = 19.7 liters (L)

100kw diesel generator set fuel consumption = 21 kilograms (kg) = 26.25 liters (L)

150kw diesel generator set fuel consumption = 31.5 kilograms (kg) = 39.4 liters (L)

200kw diesel generator set fuel consumption = 40 kilograms (kg) = 50 liters (L)

250kw diesel generator set fuel consumption = 52.5 kilograms (kg) = 65.6 liters (L)

300kw diesel generator set fuel consumption = 63 kilograms (kg) = 78.75 liters (L)

350kw diesel generator set fuel consumption = 73.5 kilograms (kg) = 91.8 liters (L)

400kw diesel generator set fuel consumption = 84.00 kilograms (kg) = 105.00 liters (L)

450kw diesel generator set fuel consumption = 94.50 kilograms (kg) = 118.00 liters (L)

500kw diesel generator set fuel consumption = 105.00 kilograms (kg) = 131.20 liters (L)
