Abstract

METODO PARA RESPONDER A LOS CAMBIOS DE CARGA EN UNA PLANTA PFBC, EN PARTICULAR PARA MEJORAR LA ACCESIBILIDAD DE UNA PLANTA PFBC QUE TIENE UN COMPRESOR (16) PARA PRESURIZAR EL RECIPIENTE DE PRESION DE LA PLANTA PFBC (10). AL OBJETO DE AUMENTAR LA POTENCIA DE LA PLANTA PFBC DESDE UN VALOR BAJO A UN VALOR ELEVADO, LA PRESION EN EL RECIPIENTE (10) SE AUMENTA PONIENDO EN MARCHA UNA TURBINA DE EXPANSION (17) CONECTADA DE FORMA DIRECTA MECANICAMENTE CON EL COMPRESOR (16), PARA QUE OPERE COMO UN SUPERCARGADOR PARA AUMENTAR EL FLUJO MAGICO DE AIRE PROCEDENTE DEL COMPRESOR.METHOD TO RESPOND TO LOAD CHANGES IN A PFBC PLANT, IN PARTICULAR TO IMPROVE THE ACCESSIBILITY OF A PFBC PLANT THAT HAS A COMPRESSOR (16) TO PRESSURIZE THE PRESSURE CONTAINER OF THE PFBC PLANT (10). IN ORDER TO INCREASE THE POWER OF THE PFBC PLANT FROM A LOW VALUE TO A HIGH VALUE, THE PRESSURE IN THE CONTAINER (10) IS INCREASED BY STARTING AN EXPANSION TURBINE (17) CONNECTED DIRECTLY MECHANICALLY WITH THE COMPRESSOR (16) , TO OPERATE AS A SUPERCHARGER TO INCREASE THE MAGIC AIR FLOW FROM THE COMPRESSOR.
