Description

technical field

[0001] The invention relates to a novel straw circulating fluidized bed combustion boiler using cotton stalks, corn stalks and branches as fuel, and belongs to the technical field of biomass straw treatment technology and fluidized bed. Background technique

[0002] my country's biomass resources are very rich, of which cotton stalks, corn stalks, and branches account for a large proportion. How to efficiently use these agricultural wastes to realize their harmlessness, reduction and recycling has become an important topic at home and abroad. Applying circulating fluidized bed combustion technology to the large-scale treatment of cotton stalks, corn stalks, and tree branches solves the shortcomings of low efficiency and high pollution of traditional treatment methods, and at the same time, it can be used for power generation or heating, replacing some fossil fuels, which will have great impact on my country's energy resources. and environmental protection str...
