Procedimiento integrado para la generación de energía eléctrica y aparato correspondiente

摘要

It is disclosed an integrated process for the production of electrical power by integration of the recovery of waste heat from a plant for the production of clinker and the recovery of heat from a plant for solar power concentration (CSP), comprising the following steps: a1) recovery of the waste heat of process gases-through supply of said process gases to a Rankine cycle where the motive fluid is water and water steam with production of saturated steam at a temperature between 250 and 275 degrees Celsius and at a pressure between 40 and 60 bar; a2) production of further saturated steam at the same conditions of temperature and pressure of step a1) through the heat generated from the CSP; b) mixing of the flow of saturated steam coming from steps a1) and a2) and overheating of the mixture to a temperature between 500 and 520 degrees Celsius; c) feeding the stream of overheated steam at a pressure between 40 and 60 bar and at a temperature between 500 and 520 degrees Celsius coming from step b) to a condensation turbine, expansion of the same steam with generation of electrical power. If is disclosed also the relative apparatus.
