FIELD: heat power engineering.
SUBSTANCE: invention relates to air-heating heating systems using gas recuperative air heaters and can be used for autonomous air heating, as well as for technological processes. Heat exchanger module comprising housing with inlet and outlet holes accommodates heat exchanger with combustion chamber and convective part with partition and rotary chamber, wherein the heat exchanger partition divides the inner space of the housing into two compartments communicating with each other through the rotary chamber, according to the invention, the rotary chamber is aligned with the combustion chamber combustion channel, and the heat exchanger partition is installed longitudinally to the combustion chamber.
EFFECT: reduced condensate formation and aerodynamic resistance of the module, higher efficiency of the installation, simplified manufacturing.
