Steam power plant provided with a retrofit kit and method for retrofitting a steam power plant

摘要

A steam power plant with retrofit kit has a steam generator (1) with superheater, a steam turbine set including condensation installations (11), connecting pipelines, auxiliary devices and a generator (10). The steam power plant (22) is distinguished by the fact that the retrofit kit includes a retrofit turbine module (25) which is designed for elevated temperature and for unchanged or modified pressure and is connected upstream of the existing steam turbine set or is exchanged for the high-pressure turbine of the latter. Furthermore, a method for retrofitting an existing steam power plant includes the following steps: connecting a retrofit turbine module (25) for high operating temperatures and unchanged or modified operating pressure upstream of the existing turbine set or exchanging the existing high-pressure turbine for the retrofit turbine module (25); providing a steam generator (1) and/or superheater (32) for high live steam temperature. This improves the efficiency and/or the service life of an existing steam power plant. The retention of as many original parts of the steam power plant as possible leads to an inexpensive solution for increasing output. Moreover, the general infrastructure can be maintained to the extent that to do so is economical and environmentally compatible.
