Main building block using fire row component as burner, performance are just particularly important.In practical work, due to fire
The defects of arranging component design, there is burner combustion it is insufficient the problem of, the nitrogen oxygen that contains of flue gas that burner is caused to discharge
The comparision contents of compound are high.
It in the prior art, can be by reducing ignition temperature during fire row component operation in design cooling device, so as to make
Fuel gas buring is more abundant, to reduce the discharge of nitrogen oxides, but increase cooling device in the burner, can increase burner
Volume, occupied space become larger, and lead to problems such as to transport, install inconvenience.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of it is simple in structure,
Low NO fire row component that is compact-sized, reducing discharged nitrous oxides.
Technical solution is used by the utility model：The utility model includes fire row and is arranged on the fire row upper end
Fire hole piece is provided at both ends with two Venturi tubes being connected inside the fire row, the Venturi tube it is narrow for lower end and by
Gradually upward widened admission line, the upper end of two Venturi tubes is both provided with water conservancy diversion indent, two Venturi tubes
Between be provided with several cooling pores, the fire hole piece upper end is uniformly provided with several fire holes, the Venturi tube and several institutes
Fire hole is stated to be connected.
Further, the fire row includes being made of two pieces of matched fire row pieces, and the both ends of the fire row piece are respectively provided with
Fluted, when two pieces of fire row pieces are in mating connection, the fit depressions of the fire row piece form the Venturi tube.
Further, two pieces of fire row pieces are connected, and by being arranged on the fire row piece lower end and left and right ends
Fixation intermediate plate be fixedly clamped.
Further, several fire holes are lined up uniform gather of two row and are arranged in the fire hole piece, the shape of the fire hole
Shape is kidney-shaped.
Further, several connecting holes are offered in the fire row, several fire row components pass through the connecting hole phase
Connect and compose burner.
The beneficial effects of the utility model are：Since the utility model includes fire row and the fire for being arranged on the fire row upper end
Hole piece is provided at both ends with two Venturi tubes being connected inside the fire row, and the Venturi tube is narrow and gradual for lower end
Upward widened admission line, the upper ends of two Venturi tubes are both provided with water conservancy diversion indent, two Venturi tubes it
Between be provided with several cooling pores, the fire hole piece upper end is uniformly provided with several fire holes, the Venturi tube with it is several described
Fire hole is connected, so, the utility model changes the Venturi tube inside the fire row by setting the water conservancy diversion indent
Airflow channel structure, and uniformly densely covered several fire holes of setting in the fire hole piece fire the even flame of the fire row
It burns, increases the burning area of the fire hole, improve the combustion power of monolithic fire row component, so as to which combustion gas be made fully to burn, have
Effect reduces the discharge capacity of fire row component nitrogen oxides；Meanwhile the cooling pore is opened up in the fire row upper end, outside cooling
Pipeline passes through the cooling pore, and the cooling water in external cooling pipe can reduce the temperature of the fire row, can also make described
Fire row burning is more abundant, reduces the discharge capacity of fire row component nitrogen oxides.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structure diagram of the utility model fire hole piece.
Specific embodiment
As depicted in figs. 1 and 2, in the present embodiment, the utility model includes fire row 1 and is arranged on 1 upper end of fire row
Fire hole piece 2, be provided at both ends with two Venturi tubes being connected 3 inside the fire row 1, the Venturi tube 3 is lower end
Narrow and gradual widened admission line upwards, the upper end of two Venturi tubes 3 is both provided with water conservancy diversion indent 4, described in two
Several cooling pores 5 are provided between Venturi tube 3,2 upper end of fire hole piece is uniformly provided with several fire holes 6, the text mound
In pipe 3 be connected with several fire holes 6.In this design, changed inside the fire row 1 by setting the water conservancy diversion indent 4
The airflow channel structure of the Venturi tube 3, and several fire holes 6 of setting uniformly to gather in the fire hole piece 2, make the fire
The even flame burning of row 1 increases the burning area of the fire hole piece 2, improves the combustion power of monolithic fire row component, so as to
Combustion gas is made fully to burn, effectively reduces the discharge capacity of fire row component nitrogen oxides；Meanwhile open up institute in 1 upper end of fire row
Cooling pore 5 is stated, external cooling pipe passes through the cooling pore 5, and the cooling water in external cooling pipe can reduce described
