锅炉燃烧调整燃用合山低质煤的合山电厂5号炉(PG-300/100-5型),在大修中炉室增设103米~2的卫燃带。在调整中从制粉系统入手,使成粉细度从R_(90)=12～30％范围稳定在12～17％;适当开大给粉机下粉挡板开度,维持正常下粉;并在配风上,针对个别火嘴附近挂焦现象,采用较高的一次风比,增加一次风刚度,从而获得较好的燃烧效果,使锅炉热效率由75.62％提高至86.13％,每年可节约原煤2.2万吨。燃用东罗、上林等低质烟煤的南宁电厂2号炉(WGZ-65/39-7型),在调整中找出了合理用风方式,对火嘴周介风及下二次风运行方式也作了调整,锅炉效率由82.63％提高至84.82％,每年可节约原煤 Boiler Combustion Heshan Power Plant No. 5 furnace (PG-300 / 100-5 type) burning Heshan low-quality coal was adjusted and an additional 103m ~ 2 deflagration belt was installed in the furnace overhaul. In the adjustment from the milling system to start, so that the fineness of the powder from the R_ (90) = 12 ~ 30% range stable at 12 ~ 17%; appropriate to open large powder machine under the baffle opening to maintain the normal powder; And in the distribution of wind, the phenomenon of hanging fire near the individual burner, the use of a higher wind ratio, an increase of wind stiffness, so as to obtain better combustion results, the boiler thermal efficiency increased from 75.62% to 86.13%, annual savings 22,000 tons of raw coal Nanning Power Plant No.2 furnace (WGZ-65 / 39-7 type) burning low-grade bituminous coal such as Dongluo, Shanglin, etc., found a reasonable way of using the wind during the adjustment, Way has also been adjusted, the boiler efficiency increased from 82.63% to 84.82%, annual savings of raw coal
