Abstract

See full text

The invention relates to a method and an apparatus for heating up a first gas-flow with a second gas-flow. The first gas-flow is caused to flow along a wall in a cylindrical chamber as a rotating gas-flow and the second gas-flow is caused to flow centrally in the chamber, surrounded by the first gas-flow, so that the wall is protected. The apparatus comprises a chamber having an inlet section designed as a whirlpool chamber and an elongate cylindrical mixing part non-radial inlets for the first gas-flow, having their orifices in the wall of the whirlpool chamber and having an inlet for the second gas-flow, arranged substantially centrally in the end of the whirlpool chamber facing away from the mixing part, as well as an outlet section arranged in the mixing chamber part opposite the whirlpool chamber.
