摘要
Abstract
If main operation parameters deviate from the target value,the boiler thermal efficiency will de-crease and the unit coal consumption will rise.Thus,the key points in calculating gas boiler thermal effi-ciency was analyzed,and the energy-loss analysis model which is suitable for gas boilers was put forward. Taking a 220 t/h blast furnace gas-fired boiler as the research object,the established model was adopted to calculate the coal consumption deviation resulted from the boiler operation parameters'variation,like the exhaust temperature,the oxygen content in exhaust,CO concentration in exhaust and so on.The results show this model can obtain the coal consumption deviation accurately,which provides a guidance for boiler optimization operation.关键词
