Method of cooling hot product gas with adhesive or fusible particles

摘要

A method for cooling a hot product gas containing adhesive or fusible particles include injecting a ring-shaped jet of a cooling fluid into a gas to be cooled in a cooling zone in a flow direction of the gas, with separation of the jet into a plurality of individual cooling fluid jets with mass and penetration depths corresponding to the mass of product gas streams flowing through individual ring-shaped parts of the cooling zone. The injection speed of the cooling fluid jets are selected so as to obtain a desired penetration depth.
