由湖南省煤炭科学研究所、中国建材研究院水泥研究所和浙江大学共同承担的国家“七五”科技攻关课题“劣质煤燃烧技术”中的“调整矸石物质组成在流化床锅炉内直接生产低标号水泥的研究”子专题近日通过了技术鉴定。沸腾燃烧是利用低热值煤产汽发电的一种先进的燃烧技术,由于低热值煤灰分高,经沸腾锅炉燃烧后的灰渣产率达60～80％。沸腾炉灰渣(简称沸渣)的一个重要用途是在其中配入30％左右的高标号水泥熟料来生 By the Hunan Provincial Coal Research Institute, Institute of Cement Research Institute of China Building Materials and Zhejiang University shared the national “Seventh Five-Year” scientific and technological project “low-quality coal combustion technology” in the “adjust the waste rock material directly in the production of fluidized bed boiler Low-grade cement research ”sub-topic recently passed the technical appraisal. Boiling combustion is an advanced combustion technology that makes use of low calorific value coal to produce steam and generates 60-80% of ash after being burned in a boil-off boiler due to the high ash content of low calorific value. An important use of boiling furnace slag (referred to as boiling residue) is in which 30% of high-grade cement clinker to be born
