高海拔地区烟煤锅炉设计与运行状况分析

对国内高海拔地区125 MW、300 MW锅炉机组进行调研,对其基本设计参数、煤质参数、制粉系统设计参数、热负荷参数以及运行状况进行了分析,并将其热负荷参数和反推到的平原地区热负荷参数进行了比较。根据分析结果,高原地区锅炉炉膛设计以及燃烧系统设计应结合高海拔特点进行特殊考虑。在高海拔地区只要合理设计炉膛参数,加上控制好煤粉细度、煤粉均匀性和煤粉管之间的风粉分配等因素,锅炉运行仍可以获得良好的燃烧效果。

Design and Operating Characteristics of Bituminous Coal Boiler at High Altitudes Areas

In this pater,the 125MW and 300MW boiler units at high altitudes areas were investigated,we analysed its basic design parameters,the coal quality parameters,the coal pulverizing system design parameters,the thermal load parameters and the running status,and the thermal load parameters and reverse on the plains of the thermal load parameters are compared. According to the analysis results,the design of the boiler furnace hearth and the burning system of the boiler at high altitudes areas should be combined with the characteristics of high altitude for special consideration. As long as reasonable design furnace hearth parameter,suitable pulverized coal fineness and uniformity,distribution of wind powder between pulverized coal pipe and other factors,the coal boiler at high altitudes areas could obtain good burning effect.
