3台设有炉前成型装置、蒸气出力为4t/h的工业锅炉已在杭州运转二年。结果表明:锅炉的运转工况正常、稳定,煤种适应性广。锅炉运转的费用因节煤、节电而低于燃用散煤,使炉前成型装置的投资可在4个月内收回。在不设置除尘器的条件下,可满足城市排烟含尘浓度的标准(200mg/Nm~3)。在掺入石灰石作用固硫剂时可脱硫近50％,这时的灰渣可作低标号水泥(175~#)的熟料。本文对有关炉前成型的设计思想、台架
Three industrial boilers with a furnace front forming unit and steam output of 4 t / h have been operating in Hangzhou for two years. The results show that the operating conditions of the boiler are normal and stable, and the adaptability of coal is wide. The cost of boiler operation due to saving coal, saving less than burning coal, the investment in front of the molding device can be recovered within 4 months. Without setting the dust collector, it can meet the city dust concentration standards (200mg / Nm ~ 3). In the incorporation of limestone solid sulfur desulfurization agent can be desulfurized nearly 50%, then the ash can be used as low-grade cement (175 ~ #) clinker. This article on the design of the furnace front design, bench
