Abstract (en)
[origin: EP2520855A1] A feedwater and draining system for medium-pressure heaters used in a power plant comprises a feedwater piping (100) and a boiler feedwater pump unit (200) provided on the feedwater piping (100).The boiler feedwater pump unit (200) includes a low-pressure boiler feedwater pump (203) and a high-pressure boiler feedwater pump (204) provided along the upstream and the downstream of the feedwater piping (100). A medium-pressure feedwater heater unit (300) comprising one or more feedwater heaters is provided between the low-pressure boiler feedwater pump (203) and the high-pressure boiler feedwater pump (204).A generator set and a power plant equipment comprising the feedwater and draining system for the medium-pressure heater are provided. The feedwater and draining system for the medium-pressure heater is low in cost, high in efficiency of thermodynamic system and more environment-friendly.
