提高6FA燃气轮机联合循环机组热态启动经济性的分析

Economy improvement analysis during hot start of 6FA gas turbine combined cycle unit

为降低联合循环机组热态启动过程中天然气的用气量,提高机组运行的经济性,通过选取适当的冲转参数与参考基准、降低汽缸温度等措施,实现机组运营成本的降低。优化后,热态启动过程中的用气量大幅下降,具有明显的经济效益。

To reduce the gas consumption of natural gas during the host start of combined cycle unit and improve the economy of plant operation,several measures such as appropriate impulse starting parameter and reference datum selection,as well as the cylinder temperature reduction are performed to achieve lower plant operation costs. After optimization,the gas consumption during hot start has a significant descent and the plant operationhas obvious economic benefits.
