Description

Technical Field

[0001] This utility model relates to a forced-draft gas water heater. Background Technology

[0002] The existing technology, Chinese patent 201410239093.3, describes a condensing gas water heater, including a flue gas heat exchange chamber and a condensing heat exchanger disposed within the flue gas heat exchange chamber. The condensing gas water heater also includes an atomizing device for collecting condensate dripping from the condensing heat exchanger and atomizing the collected condensate to be discharged from the condensing gas water heater with the flue gas. This invention, by incorporating an atomizing device, allows water vapor to be atomized again after releasing its latent heat and becoming liquid water, and then discharged outside the machine with the flue gas, preventing liquid condensate from dripping down and making the condensing gas water heater more reliable. It also avoids the potential danger of discharging acidic condensate indoors, thus providing higher safety. The existing problems are: the structure of the flue gas entering the condensing heat exchanger from the main heat exchanger is complex, and the condenser concentration is slow.
