A Brief Technical Analysis on Energy Saving and Carbon Reduction of Steam Turbine in Gas-fired Power Plant

提升进汽初参数是汽轮机节能提效的一种主要技术路径,本文针对当前在冶金煤气发电领域广泛应用的100 MW亚临界机组参数提升展开探讨。通过对比论证16.7 MPa/600℃/600℃和24.2 MPa/600℃/600℃两种升参数技术方案,对其可行性和技术经济性进行分析探讨,达到节能降碳的目的。结果表明:相比于100 MW亚临界煤气发电汽轮机,两种升参数方案技术上均成熟可行。提升参数后每年可节约用煤6 129~8 488吨,减少碳排放20 137~27 890吨。

Upgrading the initial parameters of steam Turbine is one of the main technical approaches for turbine energy saving and efficiency improvement.In this paper,upgrading the parameters of 100MW subcritical units,which are widely used in metallurgical gas-fired turbine generation,are discussed.By comparing and demonstrating the two technical schemes of upgrading parameters of 16.7MPa/600℃/600℃and 24.2MPa/600℃/600℃,the feasibility and technical economy are analyzed and discussed,so as to achieve the purpose of energy saving and carbon reduction.The results show that:Compared with the 100MW subcritical gas-fired turbine,the two schemes of upgrading parameters are technically mature and feasible,and coal consumption can be saved 6129~8488 tons and carbon emissions can be reduced 20137~27890 tons every year.
