Claim Text:
1. Method for the conveyance, cooling and energy recuperation of hot material from a combustion boiler of a combustion plant, comprising at least the following steps: a) issuing of the hot material from a material issue orifice of a combustion boiler into a capture region of a housing, a conveyor belt being arranged in the housing, b) conveying of the hot material through a cooling region in the housing, c) cooling of the hot material by means of a cooling-air stream moving in the opposite direction to the material in at least one of the following regions: d) removing at least part of the heated cooling-air stream out of at least one region adjacent to the capture region of the housing, e) delivering the removed cooling-air stream to at least one region, carrying combustion exhaust gases, of the combustion plant by a cooling-air shaft having a plurality of exits connecting variably towards various regions of the combustion plant which carry exhaust gas, wherein a dynamic, controlled and variably placed delivering of the removed part of the cooling-air stream takes place into regions of a region, carrying combustion exhaust gases, of the combustion plant, in which region a temperature of the combustion exhaust gases is lower than or equal to that of the removed part of the cooling-air stream, or, should this not be possible, into an atmosphere.
