下 饲 式燃煤机在锻造加热炉上的应用

Based on the analyse of straw characteristics ( i.e. bulk density moisture and volatile matter ) underfeed stoker and double combustion chambers are introduced in the designing of straw boiler .

通过对秸秆 物料 本身特性（堆积密度、含水率和挥发分）进行分析，在秸秆锅炉的设计中采用 下 饲 式 进 料 方式和双燃烧室结构。

The experimental results indicate that underfeed is safe and reliable . Boiler output is raised to 44 % over designed value and boiler efficiency is also increased more than 1o % .

技改 后的测试结果表明， 底 饲 过程安全可靠， 技改 效果非常明显，锅炉出力超出原设计值44%，锅炉效率也提高了10%以上。
