摘要： The once-through boiler includes a water supply and at least an economizer, an evaporator superheater. No valves are provided between the economizer, the evaporator and the superheater. The high-pressure turbine includes a control valve. The method for low load operation of a power plant with a once-through boiler and a high pressure turbine includes providing a parameter indicative of the stable operation of the once-through boiler in once-through operation, and on the basis of this parameter adjusting the control valve in order to regulate the pressure within the economizer and evaporator and/or adjusting the temperature of the water supplied to the economizer.

摘要： A steam power plant is suggested having, parallel to the high-pressure preheater passage (VW4 to VW6), a heat reservoir (A) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the high-pressure preheater passage (VW4 to VW6) into the condensate line (19.2) resp. the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.

摘要： A steam power plant is suggested having, parallel to the low-pressure passage (VW1 to VW2), a heat reservoir (A) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the low-pressure preheater passage (VW1 to VW2) into the condensate line that contacts the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.

摘要： A steam power plant with a low-pressure turbine is suggested with a second low-pressure turbine on a separated shaft line including a separate generator. The second low-pressure turbine is connected to an additional condensing system without cooling water consumption, thus allowing to maintain the power output at a high level, even if the main condensing system has a reduced capacity due to cooling water restrictions.

摘要： 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.
