Circulating fluidized bed combustion technology is a clean and low-temperature coal technology developed and promoted in recent years. Based on the summary and reference of the mature technology of domestic circulating fluidized bed boilers, our company has carried out targeted technology upgrading and product upgrading, and the technical performance of products, energy saving and environmental protection performance, operation reliability and use and maintenance have been significantly improved and improved. SHX series fluidized bed boiler using circulating suspension combustion technology, with high thermal efficiency, high desulfurization rate, low NOx emission, simple structure, easy operation and other characteristics, has a wide range of application prospects, is an ideal alternative to traditional boilers.
The temperature in furnace is 850℃～950℃, the fuel particle could reach to furnace temperature and burn rapaidly. Thus, CFB boiler could burn different type solid fuels without any auxiliary fuels.
the fuel is mixed with a large amount of high temperature bed fuels and burn rapidly, and has high combustion rate. The unburned particles are returned to furnace for circulating cumbustion by cyclone separator, lengthen combustion period, and increase co
Desulfurization process is processed under the optimum reation temperature in furnace, and the circulating system could lengthen the residence time of desulfurizer in boiler, also, the desulfurizer particle size is small as 0.1mm, the reaction contact are
The furnace temperature is keep at 850℃～950℃, the temperature is relatively low, so the NOx emission is less. Otherwise, CFB boiler adopts zoning air supply and zoning combustion, the fuel could burn sufficiently, low NOx emission.
Strong mixing and fast heat transfer in furnace, the furnace cross section has high heat load (around 3～5MW/㎡).
The fuel is combusted under low temperature, and the high combustion efficiency makes slag has low carbon content, also, there are large amount of calcium oxide and calcium sulfate, could used for cement and brick, etc.
SHX20-1.25-AII boiler is a double-barrel horizontal natural circulation boiler, the boiler room is double-layer arrangement, and the height of the boiler operating platform is generally 4000mm. The basic size of the boiler body: the boiler drum is Φ1400×16, the center elevation is 10750; The bottom drum is Φ900×14, the center elevation is 4650, and the outer dimension after installation is 13270×8430×12500 (length × width × height).
The front furnace of the boiler adopts full-mode water-cooled wall suspension structure. The separation system adopts adiabatic high temperature cyclone separator and automatic balance U-type returner. The convection tube bundle is arranged between the upper and lower cylinders to ensure sufficient heating surface. The economizer adopts the structure of two-stage cast iron economizer; Air preheater is arranged at the tail.
