Abstract

LA INVENCION SE REFIERE A UNA CONSTRUCCION DE INTEGRACION ENTRE UNA CALDERA DE VAPOR Y UNA TURBINA DE VAPOR Y A UN METODO PARA PRECALENTAR EL AGUA DE SUMINISTRO. EN LA CONSTRUCCION DE INTEGRACION EL VAPOR ES PASADO DESDE LA CALDERA DE VAPOR (10) A LO LARGO DE CONDUCTO (24A) A LA TURBINA DE VAPOR (11) PARA GIRAR EL GENERADOR ELECTRICO (12) QUE GENERA ELECTRICIDAD. EL ECONOMIZADOR (23) CONSTA DE AL MENOS DOS PIEZAS, QUE COMPRENDEN AL MENOS UNA PRIMERA PIEZA ECONOMIZADORA (23'') Y AL MENOS UNA SEGUNDA PIEZA ECONOMIZADORA (23''''). EL AGUA DE SUMINISTRO PASA DESDE LA PIEZA ECONOMIZADORA DE FRIO (23'''') A UN PRECALENTADOR DE AGUA DE SUMINISTRO, QUE CONSTA DE UN INTERCAMBIADOR DE CALOR (24) EN EL QUE SE TRASPASA ENERGIA TERMICA DESDE VAPORES EXUDADOS DE LA TURBINA DE VAPOR, DIRECTAMENTE O A TRAVES DE UN MEDIO, PREFERIBLEMENTE AGUA, EN EL AGUA DE SUMINISTRO. DESPUES DE ESTO, EL AGUA DE SUMINISTRO, QUE HABIA SIDO PRECALENTADA POR MEDIO DE VAPORES EXUDADOS DE LA TURBINA DE VAPOR, PASA EN LA CALDERA DE VAPOR (10) EN LA PIEZA ECONOMIZADORA DE CALOR (23'''') Y ADEMAS AL VAPORIZADOR (240) Y EN EL SUPERCALENTADOR (24) Y A TRAVES DEL SUPERCALENTADOR A LA TURBINA DE VAPOR.THE INVENTION REFERS TO AN INTEGRATION CONSTRUCTION BETWEEN A STEAM BOILER AND A STEAM TURBINE AND A METHOD FOR PREHEATING THE SUPPLY WATER. IN THE INTEGRATION CONSTRUCTION THE STEAM IS PASSED FROM THE STEAM BOILER (10) ALONG THE DUCT (24A) TO THE STEAM TURBINE (11) TO ROTATE THE ELECTRIC GENERATOR (12) THAT GENERATES ELECTRICITY. THE ECONOMIZER (23) CONSISTS OF AT LEAST TWO PIECES, INCLUDING AT LEAST ONE FIRST ECONOMIZING PIECE (23 '') AND AT LEAST ONE SECOND ECONOMIZING PIECE (23 '' ''). THE SUPPLY WATER PASSES FROM THE COLD ECONOMIZING PART (23 '' '') TO A SUPPLY WATER PREHEATER, WHICH CONSISTS OF A HEAT EXCHANGER (24) IN WHICH THERMAL ENERGY IS TRANSFERRED FROM VAPORS EXUDED FROM THE TURBINE OF STEAM, DIRECTLY OR THROUGH A MEDIA, PREFERABLY WATER, IN THE SUPPLY WATER. AFTER THIS, THE SUPPLY WATER, WHICH HAD BEEN PREHEATED THROUGH VAPORS EXUDED FROM THE STEAM TURBINE, PASSES IN THE STEAM BOILER (10) IN THE HEAT ECONOMIZING PIECE (23 '' ') AND ALSO THE VAPORIZER (240) AND IN THE SUPERHEATER (24) AND THROUGH THE SUPERHEATER TO THE STEAM TURBINE.
