  In the "13th Five-Year Plan", renewable energy and recycling energy equipment such as biomass boilers and waste heat boilers are the highlight. There is no reason, just because the fuel of these boilers is very valuable: renewable, low cost, Low pollution, high furnace efficiency, wide coverage... At present, more and more provinces and cities have introduced subsidies for biomass boilers and waste heat utilization boiler subsidy standards, opening up a good market for the wide application of biomass boilers and waste heat boilers prospect.

   There are many types of biomass fuels. In the boiler market, there are straw boilers, sugar aldehyde slag boilers, palm shell boilers, etc. The boilers of these boilers are roughly the same type, but the parameters of the boiler are different depending on the design of the fuel. The calculation of fuel consumption of biomass boilers and the calculation of gas consumption of gas-fired boilers are the same as the calculation of coal consumption of coal-fired boilers, and they are also determined by boiler efficiency and fuel calorific value.

Especially in terms of fuel calorific value, fuels are mostly used for combustion, and various exhaust gas temperatures exceed the condensation temperature of water vapor. It is impossible to release the condensation heat of water vapor. Therefore, energy utilization is generally based on the low level of fuel application. The calorific value is used as the basis for calculation. Different countries have different choices. Japan and North American countries are used to using high calorific value, while my country, the former Soviet Union, Germany and the Organization for Economic Cooperation and Development use low calorific value. Some countries use both calorific values.

   1. Calculation of consumption of biomass pellet fuel combustion boiler

   Hourly consumption of biomass furnace = 600,000 kcal * tonnage / fuel calorific value / boiler combustion efficiency

Take the question of how much fuel a 10-ton straw steam boiler uses in one hour as an example. One ton is 600,000 kcal. Assuming that the fuel heat is kcal and the boiler thermal efficiency is 85%, then a 10-ton biomass pellet boiler needs fuel for one hour. The amount is *10//85%, which is about kg/h.
