M701SDA 高炉煤气燃气轮机低热值试验研究

摘要

In order to redress the narrow range of operating calorie , the experimental study of low calorie running which includes com-bustion tuning, load swing, fast runback and load rejection was carried out in some domestic and overseas M 701SDA BFG firing gas turbine.The low calorie experiment of one domestic M701SDA gas turbine was introduced and the experiment results indicate the plant status such as combustion fluctuation , BPT spread and other parameters is normal while running at low calorie of 3200 kJ/m 3 .Thus, the GT operating calorie was changed from 4 400 kJ/m 3 to a range of 3 200~4 400 kJ/m 3 successfully.It means the plant could gener-ate by firing pure BFG and this will greatly improve the fuel flexibility , reliability and economical efficiency of M701SDA CCPP.%针对目前运行热值范围窄的不足，在国内外多个三菱M701SDA机组上进行了低热值运行试验，本文对国内某M701SDA高炉煤气机组的低热值运行试验研究进行了介绍，试验内容包括在各种热值条件下的燃烧调整、负荷波动、急降负荷及甩负荷试验。试验结果表明在喷嘴及燃烧室不作改造的前提下，M701SDA高炉煤气燃气轮机在3200 kJ/m 3低热值时运行状态良好，燃烧振动、BPT偏差及其它运行参数均正常。因此，机组的运行热值由以往的4400 kJ/m 3扩展为3200～4400 kJ/m 3，成功实现纯烧高炉煤气发电，极大地提高了M701SDA 联合循环机组的燃料适应性、运行可靠性及经济性。
