随着加热炉的大型化和高效化,已经广泛采用钉头炉管。为了防止炉灰在钉头间沉积,必须有良好的吹灰器。上海石油化工总厂化工一厂一台国产4,000万千卡/时常压园筒加热炉,对流室配置了16台固定式旋转电动吹灰器,1975年8月投用,采用13公斤/厘米~2的蒸汽吹灰,每日工作6次。1977年8月停工大修,炉管钉头间无明显积灰。但在使用中发现,由于吹灰器的空心旋转轴与蒸 With the furnace of large-scale and high efficiency, has been widely used nail head tube. In order to prevent the deposition of ash between the heads, there must be a good sootblower. Shanghai Petrochemical Plant Chemical Plant a domestic 40 million kcal / hour pressure cylinder furnace, convection room equipped with 16 stationary rotary electric sootblower, put into use in August 1975, the use of 13 kg / cm ~ 2 steam soot, work 6 times a day. August 1977 shut down overhaul, furnace tube head between no obvious fouling. However, found in use, due to the hollow soot blowing shaft and steaming
