摘　　要：针对哈密大南湖电厂的特殊位置(属于富煤缺水地区),而且煤质为褐煤(其发热量低、挥发性高、水分高),不利于长距离运输等特点,结合当地的煤价、主机设备、四大管道及管件价格和年利用小时数等因素的影响,对哈密大南湖电厂主机进行超超临界和超临界机组比选,在当地标煤价超过361元/吨或初投资差少于12 000万元可选用超超临界机组。The Hami Dananhu power plant located at the area rich in coal but short of water. The fuel coal of the power plant is brown coal,which has low heating value,high volatile and high moisture.There are some problems in the long-distance transportation of the brown coal.Therefore,according to the analysis results of local coal price,turbine cost,the pipelines and fittings cost and annual utilization hours,this paper compared the supercritical turbine and with the ultra supercritical turbine,and got the conclustion.The ultra supercritical Unit should be chosen in the cases that the coal price is above 361 yuan/ton or the initial cost is lower than 1.2billion yuan.
