Abstract

<p>SE PROPORCIONA UN MÉTODO PARA AJUSTAR LA PRESIÓN DEL GENERADOR DE VAPOR. EL MÉTODO INCLUYE CALENTAR Y ALMACENAR FLUIDO DE ALMACENAMIENTO DE ENERGÍA TÉRMICA. ADEMÁS, EL FLUIDO ALMACENADO SE UTILIZA PARA PRODUCIR VAPOR DEL AGUA DE ALIMENTACIÓN, SUMINISTRADO POR UN SUMINISTRO DE AGUA DE ALIMENTACIÓN (116) EN UNA DISPOSICIÓN DE GENERADOR DE VAPOR (140). LA DISPOSICIÓN (140) INCLUYE UN ECONOMIZADOR (142), UN EVAPORADOR (144) Y UN SOBRECALENTADOR (148) CONFIGURADO DE MANERA COMUNICATIVA PARA CALENTAR EL AGUA DE ALIMENTACIÓN A UNA PRIMERA TEMPERATURA SATURADA PARA AJUSTAR LA PRESIÓN DE LA DISPOSICIÓN GENERADORA DE VAPOR (140) Y PRODUCIR MÁS VAPOR. ADEMÁS, DEPENDIENDO DE LAS OPERACIONES DE CARGA TOTAL/PARTE, LA PRESIÓN EN LA DISPOSICIÓN DE GENERADOR DE VAPOR (140) SE PUEDE AJUSTAR AL RECIRCULAR EL AGUA DE ALIMENTACIÓN CALENTADA POR LA SECCIÓN DEL ECONOMIZADOR (142) ALREDEDOR DE LA SECCIÓN DEL ECONOMIZADOR (142) O MEDIANTE LA DERIVACIÓN DE LA SECCIÓN ECONOMIZADOR (142) MIENTRAS QUE AL MISMO TIEMPO MANTIENE LAS TEMPERATURAS DEL FLUIDO EN UNA ENTRADA (144A) DEL EVAPORADOR (144) Y EN UNA SALIDA (142B) DEL ECONOMIZADOR (142).</p><p> A METHOD IS PROVIDED TO ADJUST THE PRESSURE OF THE STEAM GENERATOR. THE METHOD INCLUDES HEATING AND STORAGE THERMAL ENERGY STORAGE FLUID. IN ADDITION, THE STORED FLUID IS USED TO PRODUCE FOOD WATER VAPOR, SUPPLIED BY A SUPPLY WATER SUPPLY (116) IN A VAPOR GENERATOR PROVISION (140). THE DISPOSITION (140) INCLUDES AN ECONOMIZER (142), AN EVAPORATOR (144) AND AN OVERHEATER (148) CONFIGURED COMMUNICATIVELY TO HEAT THE FEEDING WATER TO A FIRST SATURATED TEMPERATURE TO ADJUST THE PRESSURE OF THE VAPOR GENERATING PROVISION (140) ) AND PRODUCE MORE STEAM. IN ADDITION, DEPENDING ON THE TOTAL / PART LOAD OPERATIONS, THE PRESSURE ON THE STEAM GENERATOR DISPOSITION (140) CAN BE ADJUSTED BY RECIRCULATING THE POWER SUPPLY WATER HEATED BY THE ECONOMIZER SECTION (142) AROUND THE ECONOMIZER SECTION (142) ) OR BY DERIVING THE ECONOMIZING SECTION (142) WHILE AT THE SAME TIME MAINTAINING THE TEMPERATURES OF THE FLUID IN AN INPUT (144A) OF THE EVAPORATOR (144) AND IN AN OUTPUT (142B) OF THE ECONOMIZER (142). </p>
