河源电厂超超临界汽轮机凝汽器的选择及布置方案

超临界600MW机组一般采用汽轮机纵向布置和2个凝汽器横向布置的方案(即循环水进出水口都靠近A列柱), 对于采用2缸2排汽超超临界机组, 由于只有1 个单壳体凝汽器, 凝汽器换热面积较大, 从而给汽机房的布置设计带来了一些新的特点。结合河源电厂2×600MW2 缸2 排汽超超临界机组的设计情况, 对凝汽器横向布置及纵向布置这2种方案提出了分析比较。

The Choice of Condenser and Arrangement Option of Heyuan USC Power Plant

It is well known that two shell condenser is adopted in 600MW Ultra Super Critical Power Plant commonly.But for two cylinders two exhausted steam turbine generating unit, because there is only one shell condenser, so the heat exchange area is very large that put some affection on turbine hall layout design. We give some compared with axial and lateral arrangement of condenser on the basis of concept design of Heyuan USC power plant.
