METHOD OF HEAT EXCHANGER OPERATION AND HEAT EXCHANGER Russian patent published in 2014 - IPC F24H1/38 F24D3/00 

FIELD: power engineering.

SUBSTANCE: heat exchanger assembly comprises housing with burner, nozzle or combustion chamber, heat exchanger with convection channels and combustion product discharge pipe. Note here that said housing accommodates characteristic air intake zone, zone of air feed to combustion zone, fuel combustion zone, zone of heat carrier heating by combustion products and cooled combustion product discharge zone. Zone of heat carrier heating by combustion products features total area of combustion product flow channel in heat exchanger of (6.0-8.6) cm²/1 kW of the power of burner, nozzle or combustion chamber. Zone of heat carrier heating by combustion products and cooled combustion product discharge zone are separated by throttling web to make the manifold with at least one hole, its area making (0.9-1.3) cm²/1 kW the power of burner, nozzle or combustion chamber. Note also that combustion product discharge zone is communicated with air intake zone via at least one ejection channel.

EFFECT: expanded range of heat exchangers.
