FIELD: energy.;SUBSTANCE: invention relates to power engineering. Device for fluid medium heating contains first burner, providing first combustion of limiting fuel component and excess fuel component, and heat exchanger first module, in which first combustion gases produced during said first combustion, transfer heat to fluid medium. At that, device additionally contains second burner, into which first combustion gases are brought from one side, on other side is limiting fuel component for performing of limiting fuel component second combustion and at least part of unburnt excess fuel component contained in first combustion gases. At that, second combustion gases produced during said second combustion, circulate in heat exchanger second module and also transfer heat to fluid medium. Thus, combustion gases produced in each combustion circulate via combustion gases tubes, inside same common heat exchanger consisting of said heat exchanger modules, in which they transfer heat to fluid medium. Disclosed also is carrier rocket with fluid medium heating device.;EFFECT: invention increases temperature and pressure of fuel liquid component before its injection to combustion chamber.;9 cl, 3 dwg
