Abstract

LA INVENCION SE REFIERE A UN METODO PARA EL USO DE PLANTAS DE POCA ENERGIA PARA LA INTENSIFICACION DE FUNCIONAMIENTO DE PLANTAS DE POCA ENERGIA. EL ORDEN DE MAGNITUD DE LA PLANTA DE POCA ENERGIA SE ENCUENTRA EN LA BANDA DE ENTRE 3 Y 30 MW. EN EL METODO, LOS GASES DE ESCAPE (L2) SON APARTADOS DE LA CONEXION CON LA ESTRUCTURA DE LA CALDERA DE MANERA QUE EL FRENTE DE CALOR EN EL QUE LOS GASES DE ESCAPE SUMINISTRAN CALOR SEA EL ECONOMIZADOR (16) COLOCADO EN LA ESTRUCTURA DE LA CALDERA. LOS GASES DE ESCAPE SON SACADOS DE LA CALDERA A UNA TEMPERATURA DE ENTRE 95 (GRADOS) Y 150 (GRADOS) C. EN EL METODO, SE INTRODUCE AIRE DE COMBUSTION EN EL INTERIOR DEL HORNO (M) COMO PRECALENTADO MIENTRAS QUE PARA EL PRECALENTAMIENTO DEL AIRE DE COMBUSTION SE USA EXCLUSIVAMENTE EL CALOR DE CONDENSACION DEL VAPOR EXUDADO O DEL VAPOR DE RETROPRESION DE LA TURBINA O EL SUMINISTRO DE AGUA HA SIDO CALENTADO MEDIANTE DICHOS VAPORES.
