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。
針對目前運行熱值範圍窄的不足,在國內外多箇三蔆M701SDA機組上進行瞭低熱值運行試驗,本文對國內某M701SDA高爐煤氣機組的低熱值運行試驗研究進行瞭介紹,試驗內容包括在各種熱值條件下的燃燒調整、負荷波動、急降負荷及甩負荷試驗。試驗結果錶明在噴嘴及燃燒室不作改造的前提下,M701SDA高爐煤氣燃氣輪機在3200 kJ/m 3低熱值時運行狀態良好,燃燒振動、BPT偏差及其它運行參數均正常。因此,機組的運行熱值由以往的4400 kJ/m 3擴展為3200~4400 kJ/m 3,成功實現純燒高爐煤氣髮電,極大地提高瞭M701SDA 聯閤循環機組的燃料適應性、運行可靠性及經濟性。

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.
