Abstract (en)
[origin: US4700772A] The heat exchanger system is provided with a second duct part in communication with and downstream of the mixing chamber as well as a helical tube heating surface in the second duct part for conveying a working medium in heat exchange with the hot gas. A pair of branch ducts extend upwardly from the first duct part for the hot gas with the centrally disposed branch duct serving as a bypass for the hot gas. A restrictor in the form of a valve is provided at the upper end of the central branch duct to control the flow of hot gas therefrom into a mixing chamber.
