Abstract

La presente solicitud está relacionada generalmente con la depuración de un gas de combustión y, en una realización, con un dispositivo, sistema y método que modera y/o previene las deposiciones de desechos líquidos que se producen en la toma de entrada hacia una unidad de desulfurización de gas de combustión húmedo (WFGD) con el fin de mantener seca la toma de entrada y minimizar la deposición (por ejemplo el sarro de deposición) que se produce en la toma de entrada de combustión hacia la torre WFGD. En una realización, una unidad de desulfurización de gas de combustión húmedo (WFGD) y el sistema y/o método de acuerdo con la presente solicitud comprenden, junto con otras prestaciones, un sistema de prevención de sarro que comprende un dispositivo distribuidor de aire y/o un compartimiento de aire forzado ubicado cerca de la zona de transición de la toma de entrada. En otra realización, una unidad de desulfurización de gas de combustión húmedo (WFGD) y el sistema y/o método de acuerdo con la presente solicitud comprenden, junto con otras prestaciones, un sistema de prevención de sarro que comprende al menos una placa de enfriamiento ubicada cerca de la zona de transición de la toma de entrada.The present application is generally related to the purification of a combustion gas and, in one embodiment, with a device, system and method that moderates and / or prevents the deposition of liquid wastes that occur at the inlet to a unit of desulfurization of wet combustion gas (WFGD) in order to keep the inlet intake dry and minimize deposition (eg deposition scale) that occurs in the combustion inlet towards the WFGD tower. In one embodiment, a wet combustion gas desulfurization unit (WFGD) and the system and / or method according to the present application comprise, together with other benefits, a scale prevention system comprising an air distribution device and / or a forced air compartment located near the transition zone of the inlet. In another embodiment, a wet combustion gas desulfurization unit (WFGD) and the system and / or method according to the present application comprise, together with other features, a scale prevention system comprising at least one cooling plate located near the transition zone of the input socket.
