3月下旬,随着安庆石化热电厂新建干灰正压系统的全面投运,该厂的锅炉燃煤系统实现了灰水零排放。以前,该厂三台燃煤锅炉燃烧煤灰主要是经冲灰冲渣系统由灰渣泵组送往6公里之外的陈家冲灰场,这样不仅要造成大量水电消耗,同时随着多年的灰渣沉积,灰场灰位不断增高,一经暴雨就会造成灰水外流,对周边环境造成了威胁。为此,企业 In late March, with the full operation of the new dry ash positive pressure system at Anqing Petrochemical Thermal Power Plant, the boiler’s coal-fired boiler system achieved zero discharge of gray water. In the past, the three coal-burning boilers in the plant mainly used coal ash which was sent to the Chenjiachen ashfield 6 km away from the ash pump system by the ash flushing slag system. This not only resulted in a large amount of hydropower consumption, Slag deposition, ash field ash increasing ceaselessly, will lead to gray water outflow, caused a threat to the surrounding environment. To this end, business
