FIELD: radiant (infra-red) heating in decentralized heating systems. ^ SUBSTANCE: proposed method includes heating with infra-red radiant flux from tubular radiators blown with hot heat-transfer agent. System consists of separate modules; first module (in way of flow) is equipped with working burner whose thermal power is sufficient for heating the surface of beginning of tubular radiator to temperature of 500-550 C; each subsequent module, but for the last one is equipped with compensating burner whose thermal power is sufficient for restoration of temperature of surface at the beginning of compensating module to 500-550 C. Thermal power of each subsequent compensating module is lesser than that of previous one by 5-15%. Diameter of each subsequent compensating module exceeds diameter of previous one; compensating modules have similar thermal power. Last compensating module is not equipped with burner; temperature of exhaust flue gases is reduced to temperature exceeding the temperature of beginning of water steam condensation. Modules are interconnected by tight joints. ^ EFFECT: enhanced efficiency; maximum utilization factor. ^ 5 cl, 1 dwg |
