1981年我厂增添了两台SZP6.5—13型机械风力抛煤水管锅炉,由于烧的是3500大卡/公斤的劣质煤,每台产汽量仅3～4吨/时,炉膛出口处温度只有400～500℃.虽然配有两台φ1300麻石水膜除尘器,由于燃烧不好,烟囱仍然黑烟滚滚,周围居民意见很大;二次风管常常堵塞,抛煤机堵卡严重,布煤不均匀,调节性能很差,司炉工炉床拨火频繁,灰渣含碳量高达20～25％,排渣往往引起熄火;炉门伸进炉膛,造成炉门变形,耐火砖墙发裂,烟灰侵入前墙,产生向内鼓出等等问题。导致每吨纸板耗标煤达0.9～1.1吨. 该炉型的结构特点是:有两个纵向锅筒,炉膛中
In 1981, our factory added two SZP6.5-13 type mechanical wind-driven coal-fired boiler. Since it burns 3500 kcal / kg of inferior coal, each produced only 3 ~ 4 tons / hour of steam, the outlet of the furnace The temperature is only 400 ~ 500 ℃ .Although equipped with two φ1300 marsh water membrane duster, due to poor combustion, the chimney is still dark smoke, surrounding residents have a great opinion; the secondary air duct is often blocked, throwing coal machine blocking card serious, Unbalanced distribution of coal, poor regulation performance, fire department workers frequently call ash, carbon ash ash content as high as 20 ~ 25%, slagging often lead to flameout; furnace door into the furnace, resulting in deformation of the door, firebrick wall hair Crack, ash invasion of the front wall, resulting in bulging inward and so on. Resulting in consumption of standard coal per ton of cardboard 0.9 ~ 1.1 tons of the furnace structure is characterized by: There are two longitudinal drum, the furnace
