In a waste heat boiler (2) for the recovery of waste heat from a dust-laden hot gas, in particular circuit gas from a coke drying cooler, with at least one boiler flue (3) which is flowed towards from the side via at least one horizontally extending connection channel (1) and flowed through downwards by the diverted gas and has wall piping (8) and heating surfaces (11, 13, 14) flowed through by the gas, it is envisaged according to the invention that there is arranged in the transition region from connection channel (1) to boiler flue (3) an accelerating nose (1a) for the hot gas (G) flowing into the boiler flue, that there is provided on the rear wall (8a) of the boiler flue (3), which faces away from the connection channel (1), a dust separation channel (10) which is open at the top and extends essentially over the entire rear wall, and that the cross-section of the boiler flue (3), which is not included by the dust separation channel, is covered by a flow averaging device (15, 16). <IMAGE> |
