Abstract
The invention discloses a full-premixed combustor cooling device of a gas water heater. The full-premixed combustor cooling device of the gas water heater comprises a cavity body and a combustor panel. The combustor panel is positioned and arranged at an opening of the upper end of the cavity body and communicated with the interior of the cavity body. A circulation water cooling device for cooling mixed gas is further positioned and arranged between the opening of the upper end of the cavity body and the combustor panel. Room-temperature water or ice water is arranged in the circulation water cooling device, and therefore the temperature of the mixed gas in the cavity body can be effectively lowered, and the phenomena such as tempering can be avoided.
Description
Technical field
The present invention relates to fully pre-mixing gas combustion field of water heaters, relate 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 environmental protection again becomes the development trend of field of water heaters.Full premix combustion burner due to combustion gas and air mixing ratio more even, therefore can reduce excess air, thereby reduce the heat that flue gas is taken away, reach energy-conservation object; Owing to having reduced excess air, can also effectively reduce the growing amount of NOX in addition, reach the object of environmental protection.But because the combustible in all-premixing burner is a kind of damp, its flame propagation is very capable, and flame holding during burning is poor, is easy to occur tempering.In order to prevent tempering, must guarantee that the flow velocity of gaseous mixture is greater than the flame propagation velocity of fuel gas buring, and flame propagation velocity can raise and increase along with temperature, therefore prevent that the effective method of tempering from reducing fuel gas temperature exactly.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of gas heater all-premixing burner cooling device, this cooling device can effectively reduce the mist temperature in burner cavity, avoids producing tempering.
The present invention 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; Between the upper end open place of described cavity and described burner panel, also location is provided with one for the cooling water-circulating cooling device of mist.
As a further improvement on the present invention, on the upper end open periphery outside of described cavity, location is provided with a fixed frame, and described burner panel location is located on the upper surface of described fixed frame.
As a further improvement on the present invention, described cavity comprises the side plate of a pair of corresponding setting and the rear plate and the base plate that with this, side plate rear end are connected with bottom respectively.
As a further improvement on the present invention, 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 is all 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 another described many heat exchanger tubes are all opening-like, 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 invention has the beneficial effects as follows: the present invention is provided with a water-circulating cooling device by location between the upper end open place at 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 cavity, thereby can avoid producing the phenomenons such as tempering.
