35 ton CFB boiler in chemical company
Because of the direct pollution of coal burning, especially SO2 and NOX emissions. SO2 emissions are a major cause of acid rain in order to pass the furnace combustion technology improvements, reduce SO2 and NOX emissions, starting in the 60 s of the circulating fluidized bed boiler in our country, and in the 90 s and foreign companies after joint research and achieved great development, is now circulating fluidized bed boiler has been mature and widely used all over the country.
Fluidized bed combustion equipment can be divided into bubbled fluidized bed and circulating fluidized bed according to hydrodynamic characteristics, and into normal pressure and pressurized fluidized bed according to working conditions. Circulating fluidized bed boiler technology is a new type of clean combustion technology with high efficiency and low pollution. There are three main types of large circulating fluidized bed boilers: Lurgi type represented by Germany, FWPyroflow type represented by FosterWheeler of the United States, Alstorm of Finland (both merged) and Circofluid type represented by Babcock of Germany. The technology of large circulating fluidized bed in China has been mature
Concept of circulating fluidized bed boiler
Circulating fluidized bed boiler is developed on the basis of bubbling bed boiler (fluidized bed boiler). Therefore, some theories and concepts of bubbling bed can be applied to circulating fluidized bed boiler. But there is a big difference. The early circulating fluidized bed boiler has a high fluidization rate, so it is called the fast circulating circulating bed boiler. The basic theory of fast bed can also be applied to circulating fluidized bed boilers. The basic theory of bubble bed and fast bed has been studied for a long time and formed a certain theory. To understand the principle of circulating fluidized bed boiler, it is necessary to understand the theory of bubbling bed and fast bed as well as the dynamic characteristics, burning characteristics and heat transfer characteristics of materials in various states from bubbling bed to turbulent bed to fast bed.
