Pre-decomposition system for producing cement clinker from high-calorific-value coal gasification ash alternative fuel
The invention provides a pre-decomposition system for producing cement clinker from high-calorific-value coal gasification ash alternative fuel. A penultimate-stage suspension preheater of multiple stages of suspension preheaters is communicated with a first decomposition furnace of a V-shaped vortex top type combustion decomposition furnace, and a final-stage suspension preheater is communicated with a second decomposition furnace of the V-shaped vortex top type combustion decomposition furnace. Fuel adopted by a combustor arranged in the first decomposing furnace is high-calorific-value coal gasification ash. The high-calorific-value coal gasification ash is combusted at the top of the first decomposing furnace, materials enter the second decomposing furnace to be secondarily decomposed after being primarily decomposed, meanwhile, the high-calorific-value coal gasification ash passes through the first decomposing furnace and the second decomposing furnace, the standing time of the high-calorific-value coal gasification ash in the decomposing furnaces is prolonged, the burn-off rate is guaranteed, and the utilization rate is increased. Besides, the system is connected with an alkali removal and dechlorination subsystem and is used for treating alkali and chlorine elements, so that stable operation of producing the cement clinker by using the high-calorific-value coal gasification ash alternative fuel is realized, and the effects of large mixing amount, large scale and building material resource utilization of the ash are realized.
本发明提供的一种用于高热值煤气化灰渣替代燃料生产水泥熟料的预分解系统，多级悬浮预热器的次末级悬浮预热器与V型涡旋顶式燃烧分解炉的第一分解炉连通，末级悬浮预热器与V型涡旋顶式燃烧分解炉的第二分解炉连通。第一分解炉中设置的燃烧器采用的燃料为高热值煤气化灰渣。高热值煤气化灰渣在第一分解炉顶部燃烧，物料第一次分解后进入第二分解炉中进行第二次分解，同时高热值煤气化灰渣经过第一分解炉和第二分解炉，延长了在分解炉停留时间，保证了燃尽率，提高利用率。另外，与除碱脱氯子系统连接，对碱氯元素进行处理，实现高热值煤气化灰渣替代燃料生产水泥熟料的稳定运行，实现灰渣的大掺量、规模化、建材资源利用效应。
