Title:
STRUCTURE FOR PREVENTING WHITE SMOKE FOR LATENT HEAT RECOVERY TYPE HEAT SOURCE UNIT
Document Type and Number:
Japanese Patent JP3820075
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress generation of white smoke caused by the lowering of the temperature of combustion exhaust gas while attempting to raise efficiency by recovering latent heat of the combustion exhaust gas.
SOLUTION: A plurality of latent heat recovery type heat source unit 1 are provided, each of which comprises a gas burner 5 disposed in a combustion chamber 4, an air supply fan 3 for supplying air to the gas burner 5, a primary heat exchanger 6 for raising temperature of water with the heat from the gas burner 5, an exhaust passage 10 for discharging outside the combustion exhaust gas from the combustion chamber 4, and a heat exchanger 7 for recovering latent heat of the combustion exhaust gas in the passage 10. There is also provided a mixed exhaust passage 2 for suppressing generation of white smoke by mixing the combustion exhaust gasses from the individual passages 10 of the plurality of units 1.
