ABSTRACT:
The emission of solid particles during the discharging of a horizontal coking oven or furnace is substantially reduced or eliminated. For this purpose the hot air and gas convection flow which carries the solid particles substantially vertically upwardly is exposed to a shower or spray of water drops which are directed substantially horizontally into the upward convection flow. The volume, surface tension, density and speed of the water drops are coordinated relative to one another so that the water drops are loaded by taking up the solid particles whereupon the loaded drops sink down in a countercurrent flow to the upward convection flow. The solid particles carrying the water drops are removed from the convection flow by a plurality of baffles arranged in a chimney or stack in a staggered relationship so that the upward convection flow can pass through between adjacent baffles which are inclined toward respective collecting channels.
