A method and system for extracting and cooling the heavy ash while increasing the total boiler efficiency

摘要

For the heavy ashes of the type suitable for use in connection with the combustion chamber (2), in particular, for high-high flow rate obtained, for example from solid fossil fuel in the energy production system, cooling system and a (1), In and appropriate the system (1) is to be placed under the combustion chamber (2), (3), and containment casing, transport surface with the opening of the passage of cooling air (9) ( conveyor belt to have 311), to transport the heavy ash and a (31), is received in the form of a floor substantially continuous ash generated the combustion chamber (2) (311) transport surface and is suitable for transport belt (31), and a cooling means for cooling the heavy ash received the transport plane (311) on at least disposed below the (311) the transport surface and a, a cooling means with (11) a forced feed means for supplying to force the cooling air (4) area that is the divided and (4) region divided one, it is the divided It also is configured to limit the flow of air supplied therein, in use, cooling air supplied region is the divided into (4), the transport plane region (4), ( so as to cross the ash bed received the transport plane (9) and the opening 311) and (311) on the cooling system is located entirely.
