GAS HEAT-AND-POWER COMPLEX, HEAT EXCHANGER OF GAS HEAT-AND-POWER COMPLEX AND METHOD OF HOT AIR SUPPLY FOR PLENUM VENTILATION OF ROOMS, IMPLEMENTED WITH THEIR HELP Russian patent published in 2022 - IPC F24H3/00 F28F1/00 

FIELD: heating.

SUBSTANCE: invention relates to heat supply systems for various objects, both surface and underground, and is intended to obtain heat energy (hot air) and supply it to the object. In a gas heat-and-power complex, which includes a combustion chamber, a burner, at least two heat exchangers, a spreader, a blower, a smoke exhauster, an air heater, additive air supply control device, gas ducts and air ducts, heat exchangers contain convective heating surfaces, and shape of cross-section of inlet and outlet air channels is rectangular. Also disclosed is a heat exchanger of a gas heat-and-power complex as part of the system and a method of using the gas heat-and-power complex.

EFFECT: increase in the efficiency and safety of the gas heat-and-power complex operation due to the heat exchanger convective heating surfaces design simplification, increasing heat transfer coefficient, compensation of temperature stresses and increasing thermal power of the installation while maintaining overall dimensions and weight.
