SOLAR TOWER POWER PLANT ECONOMIZER AND PLANT OPERATING METHOD

摘要

The invention relates to a solar tower power plant economizer and to the plant operating method, the aim of which is to use the heat originating from heat losses generated around the solar tower receivers (3) in order to preheat the fluid supplying the superheated or saturated steam solar receivers. If the loss-generated heat absorbed by the economizer (2) is insufficient to reach the minimum temperature required, a secondary economizer (4) is used, which takes live steam (prior to entering the turbine) and increases the temperature of the water supplying the receiver (3).
