ABSTRACT:
The invention relates to a waste heat boiler construction provided in succession to a suspension smelting furnace, particularly a flash smelting furnace, in which construction the dust-bearing gases created in the suspension smelting furnace are prevented from directly flowing from the radiation section of the waste heat boiler into the convection section thereof, in order to reduce the tendency to dust build-ups caused by these gases, and in order to advantageously utilize the total volume of the waste heat boiler and to extend the residence time simultaneously. The invention also relates to a method for intensifying the mixing of gases and for extending the total residence time in the radiation section of the waste heat boiler.
