FIELD: heating equipment.
SUBSTANCE: invention can be used in tubular heat exchangers. Pipe assembly for a tubular heat exchanger according to the present invention for achieving a target comprises: a pipe which is formed in a flat shape and allows a combustion gas formed in the combustion chamber, flow along its inner part and to exchange heat with heat carrier, which flows outside from it; and a vortex generator, which is connected to inner part of pipe and causes formation of turbulence in combustion gas flow.
EFFECT: technical result is higher efficiency of heat exchange, as well as prevention of high-temperature oxidation and burnout of turbulence promoter and deformation or damage of pipes.
