大型天然气联合循环电厂对燃气轮机的选择

Gas turbine model selection for large-scale natural gas-fired combined cycle power plant

为使建成后的燃天然气电厂单位投资省、热效率高、投产后具有较好的效益,选择合适的机型至关重要。本文在充分掌握了国内外大量联合循环电厂应用实践和国际上大型燃气轮机制造厂商的产品性能特性的基础上,对我国将建设的大型天然气联合循环电厂的机组选型进行充分论证和技术经济比较,并推荐出合理的机型。

It is critically important to choose the appropriate gas turbine model,since it means less investment per kW,high thermal effi-ciency and more benefit.This paper makes full analysis and technical and economical comparison of gas turbine models for large-scale natural gas-fired combined cycle power plants to be constructed in China on the basis of fully mastering the applications of large number of combined cycle power plants at home and abroad,and product performance and characteristies of large-scale gas turbine manufacturers in the world.Also the most appropriate generating set models are recommended in the paper.
