COOLING SYSTEM FOR DRY EXTRACT OF HEAVY ASH DRAIN DURING THE STORAGE STORE IN A HOPPER

摘要

An ash cooling system in accordance with this invention, which provides a suitable number of inlets for chilled air located on the side walls of the storage bin at the top at the maximum height of the ash. Such air inlets can be connected to each other with only one pipe connected to the extractor and having such dimensions as to obtain an even distribution of cooling air over the walls of the hopper. A valve is installed on the pipe connecting the hopper to the extractor, which opens when it is necessary to provide cooling of the ash also during the storage phase. At the storage stage, when the bottom valve is closed, the cooling air entering the system, passing through the inlets on the side walls of the extractor, intersects this trajectory alternately with respect to the trajectory of air storage during normal operation.
