Here only some of the process air is routed through the hot gas generator. This variant is chosen if, on account of large plants, the volumetric flow of process gas would necessitate very large combustion chambers and high investment costs would be incurred. The use of only a small proportion of the process gas means that the combustion chamber has significantly smaller dimensions.
