This paper describes how to calculate the temperature of high - temp gas at the outlet of combustor by means of limited gas composition and analyses how errors in measuring gas composition , low calorific value of fuel , fuel composition and fuel temperature , etc . affect gas temperature
摘要叙述了一种根据有限的燃气成分推算燃烧室出口高温燃气温度的计算方法，并分析了燃气成分测量误差、燃料低热值、燃料成分及燃料温度等对燃气温度的影响。
The burners of 220 t / h boiler in henan shenhuolv power plant were retrofitted by using the pulverized coal burners with stabilized - firing cavity and cutting down the distance between up - primary air and down - primary air etc . technologies , thus the boiler was successfully converted from originally designed burning high calorific value coal to low calorific value coal , the boiler could operate stably at 50 % load without oil - firing aid and the thermal efficiency of boiler reached 89 %
摘要采用稳燃腔煤粉燃烧器并集中布置上、下一次风等技术对河南神火铝电厂220t / h锅炉燃烧器进行改造，成功地将该炉原设计燃用优质煤改燃为普通煤，并取得了改造后50 %负荷可无油稳定运行，锅炉热效率达到89 %的良好效果。
