Device for cooling clinker-containing hot gas flow and for separating clinker from hot gas flow of entrained flow gasifier system of biomass gasifier, has passage openings whose dimensions increase with immersion depth at coolant bath

摘要

#CMT# #/CMT# The device has a raw gas outlet (20) for cooled raw gas released from clinker, and an immersion pipe (3) with a lower section that is formed as a gas distributor bell jar (12) at a coolant bath (14), where the jar is radially extended. The bell jar is formed by a cone-shaped cover surface with a cross-section that is extended downward. The cover surface comprises gas passage openings (12'), which are distributed over circumference of the bell jar. Dimensions of the gas passage openings increase with immersion depth at the coolant bath. #CMT#USE : #/CMT# Device for cooling clinker-containing hot gas flow and for separating clinker from the hot gas flow of an entrained flow gasifier system (claimed) of a biomass gasifier. #CMT#ADVANTAGE : #/CMT# The dimensions of the gas passage openings increase with the immersion depth at the coolant bath, thus ensuring approximately constant separation of slag and constant gas cooling even during volumetric flow fluctuations of hot gas flow, and hence providing raw gas with quality independent of the amount of gas to large extent. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side sectional view of a device for immersion quenching of hot gas flow. 3 : Immersion pipe 12 : Gas distributor bell jar 12' : Gas passage openings 14 : Coolant bath 20 : Raw gas outlet.
