自动链排炉炉排的外形类似皮带运输机。煤由上煤机送进煤斗,再从煤斗内依靠自重落到炉排上,随炉排自前后缓慢移动。煤闸板的高度可以调节,以控制煤层的厚度。空气从炉排下面送入,于煤层运动方向相交。煤在炉膛内受到辐射加热,依次完成预热、干燥、着火、燃烧、直至燃尽。灰渣则随炉排移动到后部,经过挡渣板(俗称老鹰铁)落入后部灰渣斗由刮板出渣机排除。
链排炉的种类很多,按其结构形式一般可分为链带式、横梁式、鳞片式、倾斜式和往复式等;其中,链条式炉排和横梁式炉排因其结构的优越性、使用寿命长和操作的高机械化等特点,被广泛应用于煤泥、煤炭烘干领域,并取得良好的烘干效果。
Travelling Grate Stoker
Travelling Grate Stoker is a full automatically grate stoker with coal fire burner,it’s very similar to the beit conveyor from the profile view.The fuel (coal) the slag is fed/deslagged by scraper conveyor or lifter.There are several models of traveling grate stoker:Chain Grate Stoker,Cross Girder Grate Stoker,Flake Type Grate Stoker,Reciprocating Grate Stoker,etc.And the chain grate stoker and cross girder grate stoker are widely used for coal/coal sludge drying due to the high degree of mechanization and long using life.
