Abstract
In a system for effecting pressure control in a thermal power plant operated at low load connected fluidly in series, a relief conduit is disclosed herein. The relief conduit selectively transfers steam from a cold reheat conduit to the second extraction conduit. The plant further includes a boiler, a high-pressure turbine, an intermediate pressure turbine, a low pressure turbine, a main steam conduit for feeding steam from the boiler to an inlet of the high pressure turbine, a cold reheat conduit for feeding steam from an outlet of the high-pressure turbine through a reheat flow path in the boiler, and a first and second high pressure heaters. A first extraction conduit connects the cold reheat conduit to a first high pressure heater to transfer heat, and a second extraction conduit connects the intermediate pressure turbine to the second high pressure heater, to transfer heat.
