北京煤炭利用研究所最新研制的 WY 型系列消烟炉具为解决烟煤的消烟问题创出了一条新路。在炉型结构的设计上有了重大突破,较好地解决了节煤烟问题。烟煤是一种挥发份产率很高的煤种,在未达到正常燃烧状态之前,可燃气体中含有大量的芳香烃类化合物析出,在供氧不足、燃烧温度不高的情况下,碳氢化合物热解产生的游离碳不能充分燃烧,因而产生大量黑烟,不仅严重污染环境,而且由于燃烧不完全造成煤炭资源的浪费。为了解决这些问题,在炉具设计中的技术关键是(一)如何克服小型炉具(包括茶水炉)因周期性加煤造成的工况波动; (二)如何使用进入炉内的空气与可燃物充分混合;(三)如何使可燃气体在 Beijing Institute of Coal Research WY-type series of newly developed smoke-reducing stoves to solve the problem of smoking bitter smoke created a new road. In the furnace structure design has made a major breakthrough, a better solution to the soot problem. Bituminous coal is a kind of coal with high yield of volatile matter. Before the normal combustion state is reached, a large amount of aromatic hydrocarbon compounds are precipitated in the combustible gas. When the oxygen supply is insufficient and the combustion temperature is not high, the hydrocarbon Free carbon generated by pyrolysis can not be fully burned, resulting in a large number of black smoke, not only seriously pollute the environment, but also due to incomplete combustion caused by the waste of coal resources. In order to solve these problems, the key technical points in the design of stoves are (1) how to overcome the fluctuation of working conditions caused by periodic coal charging in small stoves (including tea stoves); (2) how to use the air entering the stoves with flammable Mix thoroughly; (c) How to make combustible gas in
