Abstract:
1. A gas cleaning unit for cleaning a main raw gas stream from a plant, the gas cleaning unit comprising: a plurality of gas cleaning chambers, each gas cleaning chamber equipped with a cleaning chamber inlet; an inlet manifold, for dividing said main raw gas stream flowing therethrough into a plurality of separate fractional raw gas streams for flow to said cleaning chamber inlets; and a plurality of heat exchangers, each heat exchanger located downstream of the inlet manifold for exchanging heat with a respective fractional raw gas stream entering a respective cleaning chamber; wherein each of the heat exchanges is arranged to generate a pressure drop in the fractional raw gas stream passing through that heat exchanger such that a leveling effect on flow rates of the individual fractional gas streams occurs to uniformly distribute flow of the raw gas to said gas cleaning chambers.
