Abstract
La presente solicitud se refiere a un sistema para extraer y recuperar energía para grandes flujos de cenizas pesadas producidas por calderas de combustible solido, capaces de disminuir la temperatura final de la ceniza extraída sin aumentar el flujo de aire que ingresa en la chimenea de la caldera, habitualmente fijada por los disenadores de calderas en un valor de aproximadamente 1,5% del aire de combustion total. Cuando el flujo de aire necesario para el enfriamiento excede la cantidad máxima permitida en la caldera, el sistema permite que el aire excedente y el posible vapor sean enviados al conducto de entrada de aire que ingresa en el intercambiador de aire/humos en el lado del aire, gracias a la separacion de los ambientes de enfriamiento producida por la propia ceniza. La separacion de los ambientes del sistema de enfriamiento es manejada en forma automática en base a una senal de temperatura de la ceniza para la descarga del sistema. Si el aire refrigerante no es suficiente para enfriar la ceniza, la eficacia de enfriamiento puede incrementarse por adicion de agua nebulizada.The present application refers to a system for extracting and recovering energy for large heavy ash flows produced by solid fuel boilers, capable of decreasing the final temperature of the extracted ash without increasing the air flow entering the boiler chimney , usually set by boiler designers at a value of approximately 1.5% of the total combustion air. When the air flow necessary for cooling exceeds the maximum amount allowed in the boiler, the system allows excess air and possible steam to be sent to the air inlet duct entering the air / smoke exchanger on the side of the air, thanks to the separation of the cooling environments produced by the ash itself. The separation of the environments of the cooling system is handled automatically based on an ash temperature signal for the discharge of the system. If the cooling air is not sufficient to cool the ash, the cooling efficiency can be increased by the addition of water mist.
