以煤为燃料的热工设备中黑烟产生的原因及预防

Bring on Reason and Preventing Method of Black Smoke in Burning Coal Thermal Equipment

分析了硅酸盐行业中以煤为燃料的热工设备产生黑烟的原因 :一是由于煤的燃烧方式 (既煤在直燃过程中煤中的挥发物受高温炽热作用在贫氧条件下裂解而致 )造成的 ,二是燃烧室的结构特点 (固定床式的炉箅所决定 )造成的。针对分析的结果 ,对煤的燃烧方式和燃烧室进行了相应的改进 ,实践结果表明 ,这种改进不仅消除了黑烟 ,改善了劳动条件及工作环境 ,而且还可以稳定燃烧室的热工制度 ,加快窑内升温速度 ,并可节约 15

This article has discussed the main reason that the black smoke is produced :one is burning method of coal when coal is burned in firebox (that break volatile up into carbon black under fervidity high temperature condition coal obtain heat which are not richness oxygen with directly burning).One is characteristic of firebox which is fixation bed fire bars form.it contra pose this instance that structure and burning method of advance have finished.practice prove this improve both eliminate black smoke and change labor environment and stabilizing heating condition in burning room and quickening speed of advancing temperature in kiln,reduce coal to 85% lift and right.
