The gas fired-boiler tray for combustion
Technical field
The utility model relates to a kind of gas fired-boiler assisted combustion device, is specially a kind of tray for combustion.
Background technology
The burner that the gas fired-boiler of prior art adopts has a fire dish usually, and combustion gas is come out from the fuel gas hole on the fire dish, combines with air in the burner hearth and burns.This combustion system is because air too disperses in burner hearth, and combustion-supporting effect is bad.Fuel gas buring is insufficient, has energy waste.Chinese patent 01227460 discloses a kind of " split type gas fired-boiler ", and it is provided with the burner that is made of discrete annular fire dish at furnace bottom, and each fire dish has independently air inlet pipeline, and the fire dish is provided with several pinkeye.Each fiery dish can close respectively or open as required.The structure of this fire dish is comparatively complicated, is easy to produce fault.
Summary of the invention
Gas fired-boiler tray for combustion of the present utility model has solved the tray for combustion incomplete combustion of prior art, the deficiency that air-breathing efficient is not high.
Gas fired-boiler tray for combustion of the present utility model comprises a tray for combustion body, and wind distributing hole and fuel gas hole are arranged on the tray for combustion body, it is characterized in that on the described fuel gas hole nozzles being arranged, and is connected to air register on nozzles, and air distribution outlet is arranged at described air register bottom.
The gas fired-boiler tray for combustion is characterized in that on the described fuel gas hole plug being arranged.
Gas fired-boiler tray for combustion of the present utility model is furnished with nozzles and air register on the tray for combustion body, make near the oxygen abundance of combustion gas nozzles, and combustion gas can be fully burned, and has saved the energy.Improved efficiency of combustion.

The specific embodiment
With reference to accompanying drawing gas fired-boiler tray for combustion of the present utility model, a tray for combustion body 1 is arranged, wind distributing hole 3 is arranged on the tray for combustion body, fuel gas hole 2 has screw thread on fuel gas hole 2.There is connector the both sides up and down of nozzles 4, and external screw thread is arranged on connector, and the connector of nozzles one end is connected with fuel gas hole 2.There is connector/hole the lower end of an air register 5, is connected with another connector of nozzles 2.Bottom at air register 5 also is shaped on air distribution outlet 6.This air distribution outlet 6 is two-way openings.
During use, above-mentioned nozzles, air register are installed on the tray for combustion body, tray for combustion is placed in the burner hearth,, can the part fuel gas hole be blocked up, reduce the gas supply amount with plug 7 if burner hearth requires gas quantity little.
But machined completes behind above-mentioned tray for combustion body, nozzles, air register, the equal casting of plug.
