Abstract
There is described here a gas water heater consisting of a blower (1), a premixing device (2), a gas burner (3), a heat exchanger (4), and a waste gas heat exchanger (5). Gas burner (3) works as super-stoichiometrically premixing burner and has a burner plate (9) which is cooled on the reverse side and which has a plurality of mixture passage openings (10). Heat exchanger (4) extends through two chambers (6, 7) which are located next to each other and through which waste gas flows in opposite directions. Condensation heat exchanger (5) works in the counter-current and consists of star-shaped section pieces through which heating water flows centrally and which are arranged vertically. Waste gas heat exchanger (5) and premixing device (2) run parallel to each other.
Claims25
A gas water heater comprising:
- a gas burner for producing waste gases;
- duct means for receiving the burner's waste gases, said duct means including a first chamber means located next to said burner for guiding the waste gases generally in a first direction, a second chamber means for guiding the waste gases in a second direction generally opposite to said first direction and a partition wall adjacent both said first and second chamber means,
- heat exchanger means for subjecting heating water passing therethrough to heat transfer from the waste gases within said first and second chamber means, said heat exchanger means crossing said partition wall and having first and second heat exchanging segments on opposite sides of said partition wall, said first segment being located in said second chamber means and said second segment being located in said first chamber means, both said heat exchanging segments being flowed through by said heating water transversely to the waste gas flowing directions in said first and second chamber means of said duct means;
- and
- said partition wall defining, spaced from said heat exchanger means, a waste gas diversion opening for passing the waste gas current from said first chamber means into said second chamber means.
