我厂新安装的两台SHL10—16/350—A_(Ⅱ2)型锅炉,运行中经常出现炉排被卡死的现象,经过仔细的观察和分析,发现是炉排上面的固定式松煤装置与炉排平面的间隙只有15mm左右,遇到煤中的铁块或煤矸时,炉排走不过去,引起煤闸门处的炉排“起拱”,卡断炉排片,使驱动排炉主轴的减速机因超负荷而损坏,松煤装置本身也变形,造成被迫停炉。因此,我们曾一度拆除松煤装置,用耙子翻动煤层,但又破坏了火床的平整,形成一个“火口”,使炉渣的含碳量高达42％。
The newly installed two SHL10-16 / 350-A Ⅱ (Ⅱ 2) type boilers in our factory often have the problem that the grate is jammed during operation. After careful observation and analysis, it is found that the fixed-type loose coal device above the grate Gap with the grate plane only about 15mm, met in the iron or coal gangue, the grate away, causing the coal grate at the gate “arch”, card off the grate film, so that the drive row of spindle The reducer due to overload damage, loose coal device itself is also deformed, resulting in forced shutdown. Therefore, once we dismantled the loose coal unit and used a rake to turn the coal seam, it destroyed the formation of the fire bed and formed a “crater” that made the slag carbon content as high as 42%.
