Abstract
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.
Claims10
A steam power plant, comprising:
- a first low-pressure turbine;
- a wet condensing system fluidly connected to the low-pressure turbine configured to directly receive and cool an entire exhaust gas from the first low-pressure turbine;
- a second low-pressure turbine;
- and
- a dry condensing system fluidly connected downstream of the second low-pressure turbine configured to directly receive and cool an entire exhaust gas from the second low-pressure turbine;
- a first steam valve fluidly connected upstream of the first low-pressure turbine;
- and
- a second steam valve fluidly connected upstream of the second low-pressure turbine.
5 more elements
A method for operating a steam power plant, the method comprising
- providing a first portion of an exhaust gas to a first low-pressure turbine;
- providing a second portion of the exhaust gas to a second low-pressure turbine;
- directly cooling an entire exhaust gas from the first low-pressure turbine by a wet condensing system;
- and
- directly cooling an entire exhaust gas from the second low-pressure turbine by a dry condensing system.
