【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。更多还原

【Abstract】 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%.更多还原
