Problems solved by technology

However, for a long time, the combustion process of combustion equipment has been dominated by direct combustion. Insufficient combustion, low thermal efficiency, serious waste of coal resources, and easy to produce soot and dust pollute the environment.
Soot is generated by the dehydrogenation, polymerization or condensation of hydrocarbon fuels. Once the soot is formed, it is very difficult to burn it. Therefore, combustion equipment that uses solid fuel to directly burn will cause soot and dust to pollute the atmosphere. environmental phenomenon

Description

technical field [0001] The present invention relates to combustion equipment, in particular to combustion equipment and boilers using solid fuel. Background technique [0002] The solid fuels available to human beings include coal, biomass such as agricultural and forestry wastes, and municipal solid waste. my country is a major producer of coal and domestic waste. At the same time, my country is rich in biomass resources, with a large amount of agricultural waste, Firewood forests and wood processing wastes are available for use, and agricultural wastes such as straw and chaff are more than 700 million tons per year, equivalent to more than 300 million tons of standard coal. [0003] In my country's energy structure, coal is the primary energy source and is mainly used as boiler fuel. In recent years, with the increasingly serious situation of environmental protection and the depletion of fossil fuels, under the support of national policies, biomass energy is actively used,...
