The invention relates to a condensation heat exchanger, related to the heat exchanger of fuel burner, for resolving the problem as low thermal efficiency, wherein a horizontal cylinder frame (8) contains a cylinder (13) formed by coiling or axially arranging heat adsorption tube (7), the outer wall of the cylinder (13) and the inner wall of the frame (8) are arranged with a space between, two ends of the heat adsorption tube (7) are respectively connected with a water inlet connector (1) and a water outlet connector (2), the frame (8) is mounted with a smoke outlet (9) with a condensed water outlet (12) under, the cylinder (13) contains a burning room with a gas burner inside, and at least one of the frame (8) is arranged with a burner mounting hole (15).
Description
Technical field:
The present invention is relevant with the heat-exchanger rig of gas burner.
Background technology:
The heat exchange straight tube of existing gas burner is arranged in the plane or is arranged in a plurality of parallel planes, directly heats water in the straight tube by duration and degree of heating, and the exhaust opening of flue gas on housing discharged.Exhaust gas temperature is generally at 160～250 ℃, and the water vapour in the flue gas still is in superheat state, can not condensation emit heat, and with fume emission, heat is wasted in a large number.High-temperature flue gas is taken away a large amount of sensible heats simultaneously, forms bigger flue gas loss together, has reduced the thermal efficiency.
The content of invention:
The purpose of this invention is to provide a kind of simple in structure, the condensed heat exchanger that heat exchange efficiency is high.
The present invention is achieved in that
Condensed heat exchanger of the present invention, the cylindrical shell 13 that has endothermic tube 7 coilings or axially-aligned to constitute in the horizontal cylindrical outer casing 8, the inwall of the outer wall of cylindrical shell 13 and shell 8 is gapped, the two ends of endothermic tube 7 are connected with water out adapter 2 with water supply connector 1 respectively, exhaust opening 9 is arranged on the shell 8, under condensation-water drain 12 is arranged, for the combustion chamber of gas burner is set, at least one end of shell 8 has burner installing hole 15 in the cylindrical shell 13.
The cross section of endothermic tube 7 is oval or circular.
Gap between the inwall of the outer wall of cylindrical shell 13 and shell 8 is at least 10mm.
The present invention is simple in structure, easy to manufacture, and is easy to install, with low cost, the heat exchange efficiency height.
The present invention utilizes the water cooling flue gas that temperature is lower in the endothermic tube, flue-gas temperature is reduced, the cylinder body outer wall condensation that water vapour constitutes at endothermic tube in the flue gas, condensed water is discharged by condensate drain outlet, and the flue gas that is cooled is discharged by exhaust opening, realizes that obvious heat of smoke discharges and water recovery latent heat discharges, and in the endothermic tube water heat absorption and be heated, realize energy recovery, improve boiler thermal output, can improve rate of heat exchange more than 8%.Pernicious gases such as CO in the flue gas and NOX are reduced greatly.Endothermic tube is compared with existing heat exchanger tube, and heat conductivility has improved more than 2 times.
