秸秆锅炉驱动超超临界机组给水泵汽轮机经济性分析
摘要
以新建超超临界1 000 MW机组为例
探讨了采用燃烧秸秆的高压锅炉代替汽轮机抽汽驱动给水泵汽轮机的可行性
并给出燃烧秸秆锅炉蒸汽系统的基本流程。在对机组变工况计算的基础上
分析了采用秸秆锅炉后机组煤耗率的变化以及能够获得的经济效益和环保效益。
Abstract
Taking newly constructed ultra-supercritical 1 000 MW unit as example
an approach to the feasibility of adopting straw-burning high-pressure boiler for replacing extracted steam from the main turbine to drive the small turbine of feed-water pump has been made
the basic flow process of steam system for the straw-burning boiler being put forward.Based on the calculation of variable operating condition
the change of specific heat consumption and coal consumption rate of said unit
as well as the economic and environmental benefits may be obtained from said unit after adopting the straw-burning boiler have been analysed.
