循环流化床锅炉与往复炉排锅炉性能及应用

Performance and Application of Circulating Fluidized Bed Boilers and Reciprocating Grate Boilers

对比分析循环流化床锅炉与往复炉排锅炉性能及经济性,给出3个锅炉应用案例。指明在选择燃用低热值煤的锅炉时,当单机蒸发量低于300 t/h(热容量低于210 MW)时,应优先考虑大型往复炉排锅炉;如果燃料低位发热量低于12560.4 k J/kg时,应选择循环流化床锅炉。

The performance and economy of circulating fluidized bed boilers and reciprocating grate boilers are compared and analyzed,and three boiler application cases are given.It is indicated that when selecting a boiler with low calorific value coal,the large reciprocating grate boiler should be given priority when the single unit evaporation is less than 300 t/h(heat capacity is less than 210 MW).If the low calorific value of the fuel is lower than 12560.4 kJ/kg,the circulating fluidized bed boiler should be selected.
