Abstract (en)

[origin: EP0772010A1] The air is indirectly heated by the heater. It is separated into two streams (B,C). One stream (B) is heated in cross-counterflow with flue gas in a heat exchanger (22). The other stream (C) is heated by passing uniformly around a combustion chamber (16) jacket. The two streams are passed through the heating plant without intermixing. Preferably, the combustion chamber is rotationally-symmetrical and the main dimension of the chamber is in the direction of the axis of rotation. The second air stream passes through an enclosed flow duct (34) which surrounds the combustion chamber.
