摘　　要：燃气轮机联合循环发电效率比常规电厂高10个百分点左右。适合钢铁厂低热值煤气燃气轮机有单筒燃烧器和多筒燃烧器二种类型。容量应按钢铁厂富余煤气量呈正态分布的规律计算确定。文章还介绍了轴制、煤气预处理、电网联网等特殊问题。50MW左右的机组己有国产化的实例。The generating efficiency of gas turbine combination cycle is about 10%higher than that of common generating plants. The gas turbine using a low caloric value gas, which is suitable for iron and steel plants, has both single and multi tube type burner. Its capacity should be counted and determined according to the law of normal distribution of the surplus gas amount in an iron and steel plant. In this paper, some special problems such as the shaft system, pre treatment of gas, electric network connection, etc. are introduced. The unit of approximately 50MW has been manufactured in our country.
