摘　　要：对中小型锅炉煤改甲醇的具体方法、改造前后的经济性和环保性等进行了分析,研究结果表明,中小型锅炉改造以甲醇为燃料工艺技术可行,改造过程简单,比新建锅炉节省30%~45%投资,改造后热效率大大提高,环保效益明显。在目前的甲醇价格下,改造后的运行成本略高于以煤炭为原料。当热值为4 000 Kcal/kg(16.72 MJ/kg)煤炭450元/t,甲醇1 000元/t时,锅炉年运行成本相近。The specific methods of middle and small boiler coal to methanol, before and after the transformation of economy and environmental protection are analyzed, the results show that the middle and small boiler using methanol as fuel technology is feasi- ble, transformation process is simple, save 30%-45% investment than new boiler, reformed greatly improved thermal efficiency, environmental protection benefit is obvious. Under the current price of methanol, after transforming the running cost is slightly higher than the coal as fuel. When the heating value of 4000 kcal/kg （16.72 MJ/kg） coal 450 yuan/t, methanol is 1000 yuan/t, the boil- er operation cost is similar.
