Abstract
The arrangement for cooling a hot product gas containing adhesive or fusible particles which lose their adhesiveness during cooling, has a reactor for producing the hot product gas, a cooling duct connected with the reactor for the hot product gas, a nozzle ring subdivided into a plurality of chambers mounted adjacent to and communicating with the cooling duct, each of the chambers being structured to introduce a different ring-shaped jet of cooling fluid into the hot product gas in the cooling duct. The different ring-shaped jets are producible with mass and penetration depths according to the mass of a product gas stream flowing in a cooling zone of the cooling duct with injection speeds selected to obtain a predetermined penetration depth. Using different penetration depths for the different ring-shaped jets allows avoidance of baked deposits on the walls of the reactor and cooling duct.
