Abstract

In a method of wetting particles contained in a gas stream including particles and gas, a primary gas stream containing the particles is separated into first and second gas streams such that the first gas stream includes substantially all the particles of the primary gas stream. The particles are wetted in the first gas stream with water in a wetting stage. The amount of water which is introduced into the wetting stage exceeds that amount of water which is capable of reducing the temperature of the first gas stream below its dew point. The resulting first and second gas streams are then combined into an aggregate gas stream downstream of the wetting stage to produce an aggregated gas stream having a temperature greater than the dew point of the aggregated gas.
