安阳电厂5号炉配风扇磨煤机,燃用贫煤。由于风扇磨对贫煤不适应,长期以来存在着燃烧不稳、经常灭火放炮、耗用燃油多的问题.对燃烧器做了改进后,不仅燃烧稳定,提高了锅炉运行的安全性,而且收到了节约燃油和厂用电,多发电的经济效果。一、设备简况与改前情况该炉系武汉锅炉厂制造的次高压炉,额定蒸发量230t/h,过热蒸汽压力70kg/cm~2,过热蒸汽温度485℃,锅炉设计效率为90.8％。炉膛宽度和深度分别为8m和7.36m,炉膛容积为1009m~3,容积热负荷为149×10~3kcal/m~3.h。炉膛四角各安装一组直流燃烧器,每组燃烧器
Anyang Power Plant No. 5 furnace fan mill, burning lean coal. Due to the fan mill is not suitable for lean coal, there has been a long history of unsteady combustion, often fire extinguishing, fuel consumption more problems .After the improvement of the burner, not only stable combustion, increased boiler operation safety, and income To the economical fuel and power plants, more economic power. First, the equipment profile and change the situation before the furnace Wuhan Boiler Factory sub-high-pressure furnace, rated evaporation 230t / h, superheated steam pressure 70kg / cm ~ 2, superheated steam temperature 485 ℃, boiler design efficiency of 90.8%. Furnace width and depth were 8m and 7.36m, the furnace volume of 1009m ~ 3, the volume heat load of 149 × 10 ~ 3kcal / m ~ 3.h. Each of the four corners of the furnace is equipped with a set of DC burners, each set of burners
