引进美国CE公司技术生产的 2 0 0 8t/h - 18 2 6 -YM2型锅炉在实际运行中存在一系列问题 ,主要表现为炉膛两侧烟温偏差大 ,主、再热蒸汽温度偏差大 ,一、二次风温度低 ,制粉系统干燥出力不能满足煤粉变化的要求等。针对以上问题进行了较全面的锅炉热力特性试验 ,布置了大量的锅内、炉内测点并且利用抽气热电偶实测炉膛出口烟温 ,结合美国CE公司热力计算反推程序 ,进行全面的正、反热力校核计算 ,最后调整了再热器和经济器受热面面积 ,并把后屏至末级过热器连接管由交叉改为平行 There are a series of problems in the actual operation of the 2 0 0 8t / h - 18 2 6 -YM2 type boiler introduced by the technical production of the United States CE Company. The main problems are that the flue gas temperature deviation on both sides of the furnace is large, the temperature deviation of the main and reheat steam is large, First, the secondary air temperature is low, dusting system, dry output can not meet the requirements of changes in pulverized coal. In order to solve the above problems, a comprehensive boiler thermal performance test was conducted, a large number of in-pot and in-furnace measuring points were arranged, and the outlet temperature of the furnace outlet was measured by the exhaust thermocouple. , Anti-heat check calculation, the final adjustment of the reheater and economizer heating surface area, and the rear screen to the last superheater connecting pipe from cross to parallel
