摘要： 国产200 MW汽轮机由于其三缸三排汽的特殊设计方式，在供热过程中受到较大限制，供热能力较差、能耗指
标较高。在纯凝发电过程中，汽轮机热耗偏高。论述对该机型进行改造技术，分析改造后的成效，以期对相关工作有所
助益。

Abstract: Due to the special design, the heating capacity of a 200 MW unit with triple-cylinder and triple-exhaust is limited.
The unit has the characteristics of poor heating capacity and high energy consumption. The heat consumption of steam turbine is
high, and the energy consumption is poor in the process of pure power generation. This paper discussed the transformation, and
analyzed the effects of the model after transformation in hoping to be helpful to related work. Key words: 200 MW unit; triple-cylinder and triple-exhaust; heat supply; high back press; coal consumption rate
