Fire row upper end is provided with fire hole piece, the fire row provided with two Venturi tubes being connected, and the Venturi tube upper end is set
There is stop compressing tablet.
Further, gas pipeline is provided with inside the two ends of the nozzle holder, if the gas pipeline is provided with
The dry fuel gas hole being connected with the Venturi tube.
Further, several fire holes are uniformly densely covered with the fire hole piece.
Further, the Cooling Holes are located at the middle part of the fire row and close to the connection of two Venturi tubes
At pipe, the communicating pipe curved shape.
Further, be provided with connecting plate on the two ends of the nozzle holder, the connecting plate include connecting lateral plate and
With the integrally formed connecting bottom board of the connecting lateral plate, the lower section of the Cooling Holes is provided with screwed hole one, and the connecting lateral plate is set
There is the screwed hole two that the screwed hole one is adapted, the connecting lateral plate is bolted to connection with the fire row, the company
Base plate is connect to be fixedly connected also by bolt with the nozzle holder.
Further, the stop compressing tablet by the caliber in the Venturi tube from the centre of the two lateral Venturi tubes
Portion retracts.
The beneficial effects of the utility model are：Because the utility model includes setting on nozzle holder, the nozzle holder
There are several fire rows, a Cooling Holes, the compact low-nitrogen oxide discharging burner are equipped with several described fire rows
Cooling siphunculus that is being adapted provided with one with the Cooling Holes and crossing all Cooling Holes, the fire row upper end is respectively provided with
Have provided with two Venturi tubes being connected in fire hole piece, the fire row, the Venturi tube upper end, which is provided with, stops compressing tablet, so
The utility model can reduce the heat of fire row side wall by the water circulated in the cooling siphunculus, so as to reduce nitrogen oxides
Discharge, therefore the cooling siphunculus can not only reduce the discharge of nitrogen oxides, and it is that single tube passes through the fire row, makes its entirety
Compact conformation, and the cooling siphunculus is also convenient for the connection of the utility model and external pipe；Nozzle holder described further will
Fuel gas transmission to the Venturi tube is burnt, and now occurs that the combustion gas of the both sides of the Venturi tube is less than the literary mound
In pipe center section so that ignition temperature is uneven, and the stop compressing tablet can just solve this problem very well, described
Stop that compressing tablet, by reducing the space of the center section of the Venturi tube, makes the distribution of combustion gas evenly, so that the fire
The ignition temperature of row is uniform.
