To calculate how much biomass fuel a power plant can consume, we need to know knowledge about biomass power plants.
In one respect, calculating the biomass fuel consumption of a power plant is actually calculating the biomass fuel consumption of the biomass boiler. This is related to the power generation principle of the power station. Most biomass power plants use direct-fired combustion systems. Direct combustion systems feed biomass fuel(such as biomass pellets, wood fuel, palm shell, bagasse) feedstock into a combustor or furnace, where the biomass is burned with excess air to heat water in a boiler to create steam. Steam from the biomass boiler is then expanded through a steam turbine, which spins to run a generator and produce electricity.
To calculate the fuel consumption of a power plant, we need to calculate the fuel consumption of the biomass boiler. This requires knowledge of steam parameters, boiler thermal efficiency, and boiler capacity.
Fuel Consumption = Heat Input required (kcal/hr) / Calorific Value of fuel (kcal/kg)
Heat Input required (kcal/hr)= (Boiler Capacity x (Steam Enthalpy - Feed water Enthalpy))/(Boiler Efficiency)
This method can roughly estimate the biomass fuel consumption, but in actual operation, the results will be different. There are many types of biomass fuels, and the water content, ash, morphology, and size of biomass fuels have a great influence on the calorific value of fuels. In the operation of the boiler, the environment in which the boiler is located, the state of operation of the boiler, water quality and other factors will affect the energy conversion efficiency.
