1978年,我厂安装一台DHL10-13型锅炉。试运行时,燃烧工况尚佳,但遇到湿度高(或用汽量大)需要加厚煤层时,便出现燃烧不完全的现象,导致灰渣热损失大,灰渣含碳量高。为了使煤充分燃烧,我们在链条炉排上安装了一个简易的翻煤器(见图)。翻媒器用50 × 5角钢与 50 × 5扁钢焊接而成, In 1978, our factory installed a DHL10-13 boiler. At the time of trial operation, the combustion conditions are still good. However, when the coal seam needs to be thickened due to the high humidity (or large amount of steam used), the phenomenon of incomplete combustion occurs, resulting in large heat loss of ash and high carbon content of ash. In order to fully burn the coal, we installed a simple coal turning device on the grate (see photo). Turn the media with 50 × 5 angle and 50 × 5 flat steel welded together,
