一、概述 双层炉排燃烧锅炉具有效率高,消烟除尘好,操作简单,减轻司炉劳动强度等优点。锅炉效率一般为65～75％。远高于一般手烧炉。烟气含尘量一般在200毫克/标米~3以下。故很多单位以这种型式锅炉取代其它燃烧型式的手烧炉。但是双层炉排燃烧锅炉也曾出现各种各样的问题。其原因除运行操作不当之外,主要是结构设计不合理而引起水循环的不可靠。为了搞清楚水循环对水冷炉排设计及运行的影响,进行了水冷炉排水循环理论计算和实验研究。
First, an overview of double grate combustion boiler with high efficiency, good smoke and dust removal, simple operation, reducing the labor intensity and other advantages. The boiler efficiency is generally 65 ~ 75%. Much higher than the average hand furnace. Flue gas dust content is generally 200 mg / standard meter ~ 3 below. Therefore, many units use this type of boiler to replace other burning type hand furnaces. However, the double grate combustion boiler has also had various problems. The reasons for the operation of improper operation, mainly due to structural design is not reasonable and cause water cycle is not reliable. In order to find out the effect of water circulation on the design and operation of water-cooled grate, the theoretical calculation and experimental study of water-cooled furnace drainage cycle were carried out.
