Steady flame plate is included, steady flame plate includes main body plate portion and the end plate positioned at two ends,
It is provided with the main body plate portion along the air slot of its short transverse, is set on the sidewall paneling of gas-air premix chamber
There are several gas-air ventholes, air slot is relative with gas-air venthole；
Main body plate portion is fitted with the wallboard of gas-air premix chamber, and end plate is fixed with the end of gas-air premix chamber and connected
Connect.
A kind of described low NO, it is characterized in that：The main body plate portion includes upper straight-plate portion and declined board
Portion, having in upper straight-plate portion has dovetail groove in linear burning groove, oblique plate portion, the lower end of linear burning groove is upper with dovetail groove
End connection constitutes the air slot；
Upper straight-plate portion fits with gas-air premix chamber, and gas-air venthole and dovetail groove are relative.
A kind of described low NO, it is characterized in that：The gas-air premix chamber include upper diffusion chamber and
Lower compression chamber, the gas-air venthole is located in lower compression cavity wall.
A kind of described low NO, it is characterized in that：The burner plate is in the shape of the letter V, and it includes two swash plates,
There is the angle less than 180 degree between two upper surfaces of swash plate；Burner port group is provided with swash plate.
A kind of low NO of the present invention, because using such structure, the setting of stable flame piece forms the part of burner plate
The full premixed flame that premixed flame and stable flame piece are formed is combined；The reaction speed of burning can be accelerated, oxynitrides is reduced
Discharge is more environmentally-friendly；Also can prevent the partly-premixed flame of burner body fire hole from producing the situation for taking off fire.
