Description

Technical field [0001] The invention belongs to the technical field of circulating fluidized bed combustion, and in particular relates to a combustion optimization control method of a circulating fluidized bed boiler based on fuzzy adaptive inference. Background technique [0002] As the world's largest developing country, my country currently ranks third in the world in energy production and second in basic energy consumption. However, because my country is rich in coal and lacks oil and gas, a structure dominated by coal has been formed. 50% to 60% of coal is used for power generation, which has become the main source of coal-burning pollutants. Therefore, the development of clean coal power generation technology to improve power generation efficiency and reduce pollution emissions has become an important aspect of my country's energy strategy. Circulating fluidized bed combustion technology is becoming the focus of the development of clean coal combustion technology at home a...
