国家计委、国家经 贸委对全国工业锅炉的 抽样调查分析表明，目 前，我国工业锅炉平均 运行热效率只有６０％ 左右，其中６－１０ｔ／ｈ 锅炉热效率只有 ５３． １％，大大低于国家 规定标准（国标为 ７２％）。而在锅炉各项 热损失中，排烟热损失 平均为１４．２％，最高 达３ National Planning Commission, the State Economic and Trade Commission on the national industrial boiler sampling survey shows that at present, the average operating efficiency of industrial boilers in China only about 60% thermal efficiency, of which 6-10 t / h boiler thermal efficiency of only 53. 1%, much lower than the national standard (national standard is 72%). In the heat loss of the boiler, exhaust heat loss averaged 14.2%, up to 3
