How to Calculate Biomass Boiler Fuel Consumption

With society's growing demand for energy, as the main energy source, fossil fuel is decreasing rapidly. Therefore, looking for a renewable alternative energy resource becomes the focus of social attention. Biomass as an ideal renewable energy, in the current world energy consumption, is paid more and more attention to. Because the fuel of these boilers is very valuable: renewable, low cost, low pollution, high furnace efficiency, wide coverage. So, how to calculate the fuel consumption of biomass fired boiler.

There are many kinds of biomass fuels in the boiler market, such as straw boiler, palm shell boiler, rice husk boiler, wood fired boiler, etc. The calculation of fuel consumption of biomass boilers is the same as that of gas fired boilers and coal fired boilers. It is also determined by boiler efficiency and fuel calorific value.

Especially in terms of fuel calorific value, fuel is mostly used for combustion, all kinds of exhaust smoke temperatures exceed the condensation temperature of water vapor, it is impossible to release the condensation heat of water vapor. Therefore, in energy utilization, the low calorific value of fuel application is generally used as the calculation basis. Different countries have different choices.

Biomass fired boiler fuel consumption calculation

Biomass consumption per hour of biomass boiler =60 million kcal * tonnage / fuel calorific value / boiler combustion efficiency

Taking how much fuel to use for a 10-ton straw steam boiler per hour as an example, a ton is 600,000 calories. Assuming that the heat of fuel is 4,000 kcal and the thermal efficiency of the boiler is 85%, 10 ton biomass pellet boiler fuel consumption per hour: 600,000*10/4,000/85%, which is about 1,800 kg/h.
