qthuajiao气化焦(eoke for gasifieation)专用于生产煤气的焦炭。主要用于固态排渣的固定床煤气发生炉内,作为气化原料,生产以co和H:为可燃成分的煤气。气化过程的主要反应有: C+02—~K)02十408177kJ COZ+C一2C0一162142kJ C+H:0一CO十H:一1 18628kJ C+2H20一一,COZ+2H2一75115kJ因为产生Co和H:的过程均是吸热反应,需要的热量由焦炭的氧化、燃烧提供,因此气化焦也是气化过程的热源。气化焦要求灰分低、灰熔点高、块度适当和均匀。其一般要求如下:固定碳>80%;灰分<巧%;灰熔点>1250‘C;挥发分<3.0%;粒度15~35~和>35mm两级。气化焦的灰分高则热值低,为了提供足够热量,产生单位容积煤气的焦炭耗量就会增加。气化焦的灰熔点低时,在固态排渣的发生炉内易产生熔渣现象,结成的大块渣会引起鼓风分布不均匀,降低气化效率,并使由渣带走的碳量增多。气化焦的粒度范围影响气化过程的传质和传热条件,故要求其最大与最小粒度的比值不超过2:1。冶金燕虽可以用作气化焦,但由于受炼焦煤资源和价格等的限制,一般不用冶金焦制气。以高挥发分粘结煤为原料生产的气煤焦,块度小、强度低,不适用于高炉冶炼,但它的气化反应性好,可取代气化焦用于制气。 (陈明岳姚昭章)
