How to Calculate Oil Fired Boiler Fuel Cost

We know that oil is more expensive compared with natural gas, coal and biomass. At present, the common series of condensed fuel boilers are mainly light diesel boilers, methanol boilers, ethanol boilers, alcohol-based fuel boilers and so on. Because of the particularity of the oil fired boiler, its combustion efficiency is generally more than 95%, coupled with the high calorific value of oil, so, about the calculation of fuel consumption of oil fired boiler, it is easy to get a satisfactory result for the customers who want to buy oil-fired boiler.

1. Fuel consumption calculation of high efficiency oil fired boiler

(1) Hourly fuel consumption of oil fired steam boilers in operation = hourly gas production of oil fired steam boilers *(fuel steam heat-feed water heat) / fuel low calorific value * boiler thermal efficiency

(2) Per hour fuel consumption = water weight (Kg) * specific heat capacity of water * temperature difference (temperature difference between inlet and outlet water) / fuel heating value * boiler thermal efficiency

The above two methods are more specific, but in fact, we can use the unified calculation formula of boiler fuel consumption to roughly estimate, and so on after truly determining the boiler parameters, then by the boiler manufacturer's engineers to accurately calculate.

General formula for oil consumption per hour of oil fired boiler: 3600* thermal power / fuel calorific value / boiler thermal efficiency

Taking a 10 ton oil fired boiler as an example, its thermal power is 7MW. Assuming that the combustion heat value of an oil fired fuel is 42Mj/kg and the boiler fuel efficiency is 95%, it can be concluded that a 10 ton boiler needs fuel consumption per hour = 3600*7/42/0.95, which is about 630 kg. Then, 10 ton oil fired boiler fuel cost = local oil price X630.
