1. A power plant comprising:
a water/steam power cycle comprising:
a pressure series of steam turbines including:
a high pressure steam turbine;an intermediate pressure steam turbine;a low pressure steam turbine;a re-heater fluidly located between the high pressure steam turbine and the intermediate pressure steam turbine; and a lignite dryer having:
a heater connected to a steam portion of the steam/water power cycle so as enable utilisation of steam energy in the lignite dryer,wherein the connection to the steam portion of the steam water power cycle comprises:
a first extraction line, fluidly connected to the water/steam power cycle between the high pressure turbine and the intermediate pressure steam turbine, the first extraction line further including an ejector; a second extraction line, fluidly connected to the water/steam power cycle between the intermediate pressure steam turbine and the low pressure steam turbine,wherein the configuration and location of the ejector and the connection of the second extraction line to the ejector enables a lower pressure steam in the second extraction line to be fed into the heater together with a higher pressure steam of the first extraction line. |
