FIELD: heat exchange.
SUBSTANCE: invention relates to device (1) for recuperation of waste gas heat, which during operation of exhaust gas source generating exhaust gas flows through gas outlet system (2). At that, gas outlet system (2) contains at least one waste gas neutralization device (3), as well as at least one heat exchanger (4), wherein heat exchanger (4) is located downstream and/or inside waste neutralization device (3) gas, and through waste heat exchanger (4) waste gas flows, as well as working medium for heat transfer to working medium. Besides, heat exchanger (4) comprises main flow channel (6), surrounded by additional flow channel (5), as well as heat exchange element (7) located inside additional flow channel (5), wherein downstream of outlet (8) of main flow channel (6) of heat exchanger (4) is channel gate (9), which serves to control volume flow through main flow channel (6) and/or additional flow channel (5).
EFFECT: device for recuperation of waste gas heat is disclosed.
