Abstract
The utility model discloses a full-premixing combustor cooling device for a gas water heater. The device comprises a cavity and a combustor panel, wherein the combustor panel is positioned and arranged at an upper end opening of the cavity and is communicated with the inner part of the cavity; a circulating water cooling device for cooling mixed gas is further positioned and arranged between the upper end opening of the cavity and the combustor panel; and the circulating water cooling device is internally filled with constant-temperature water or ice water so as to effectively reduce the temperature of the mixed gas in the cavity, and therefore, phenomena of annealing and the like can be avoided.
Description
Technical field
The utility model relates to the fully pre-mixing gas combustion field of water heaters, relates in particular to a kind of gas heater all-premixing burner cooling device.
Background technology
Along with the reinforcement of people's energy-conserving and environment-protective consciousness, the water heater of energy-conservation again environmental protection becomes the development trend of field of water heaters.Therefore the full premix combustion burner can reduce excess air because combustion gas and air mixing ratio are more even, thereby reduces the heat that flue gas is taken away, and reaches energy-conservation purpose; Owing to reduced excess air, can also effectively reduce the growing amount of NOX in addition, reach the purpose of environmental protection.But because the combustible in the all-premixing burner is a kind of damp, its flame propagation is very capable, and the flame holding during burning is relatively poor, is easy to occur tempering.In order to prevent tempering, must guarantee the flow velocity of gaseous mixture greater than the flame propagation velocity of fuel gas buring, and flame propagation velocity can raise and increase along with temperature, prevent that therefore the effective method of tempering from reducing fuel gas temperature exactly.
Summary of the invention
In order to overcome defects, the utility model provides a kind of gas heater all-premixing burner cooling device, and this cooling device can effectively reduce the mist temperature in the burner cavity, avoids producing tempering.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of gas heater all-premixing burner cooling device, comprise cavity and burner panel, described burner panel location is arranged at the upper end open place of cavity, and communicates with described inside cavity; Also the location is provided with a water-circulating cooling device for the mist cooling between the upper end open place of described cavity and described burner panel.
As further improvement of the utility model, be provided with a fixed frame in the location, the upper end open periphery outside of described cavity, described burner panel location is located on the upper surface of described fixed frame.
As further improvement of the utility model, described cavity comprise the side plate of a pair of corresponding setting and respectively with this rear plate and base plate that side plate rear end is connected with the bottom.
As further improvement of the utility model, described water-circulating cooling device is comprised of water inlet pipe, outlet pipe and many heat exchanger tubes, wherein, one end of described inlet tube and outlet tube is all opening-like, the other end of described inlet tube and outlet tube all is closed, and described inlet tube and outlet tube is fixedly connected with this upper end lateral wall to the side plate of corresponding setting respectively; The two ends of described many heat exchanger tubes are all opening-like in addition, and an openend of every heat exchanger tube all communicates with described water inlet pipe, and its another openend all communicates with described outlet pipe, and described many heat exchanger tubes all abut on the lower surface of described burner panel.
The beneficial effects of the utility model are: the utility model is provided with a water-circulating cooling device by location between the upper end open place of burner cavity and burner panel, normal-temperature water or frozen water are housed in this water-circulating cooling device, can effectively lower the temperature to the mist temperature in the cavity, thereby can avoid producing the phenomenons such as tempering.
