Summary of the invention:
Object of the present invention is exactly in order to solve the deficiency of prior art, and provide simple in structure, premixed combustion is effective, the full premix injection of the Draught gas burner of obvious energy conservation control device.
The present invention's adopted technical scheme of dealing with problems is achieved in that and the present invention includes burner, premix barrel, Wen Qiuli pipe, blast switch, blower fan and gas joint; It is characterized in that: between the high pressure air port and the premix barrel of burner of blower fan, or the air inlet place of blower fan is provided with induction tunnel; In induction tunnel, be provided with Wen Qiuli pipe, between the contraction chamber of Wen Qiuli pipe and expansion cavity, be provided with Wen Qiuli waist hole, Wen Qiuli waist hole be circular or grows linear hole; The gap that has 3-8 millimeter between Wen Qiuli waist hole and induction tunnel, forms negative pressure cavity.
On induction tunnel, being mounted with gas joint communicates with negative pressure cavity; In gas joint, be provided with throttling valve core, in throttling valve core, have throttle orifice.
In high pressure air port, place is provided with pressure tap, communicates with blast switch;
At air inlet, place is equipped with air register.
Compared with the prior art, beneficial effect is embodied in the present invention:
1, the present invention adopts Wen Qiuli pipe is set in induction tunnel, between the Wen Qiuli of Wen Qiuli pipe waist hole and induction tunnel, there is the gap of 3-8 millimeter to form negative pressure cavity, when the wind blasting passes through expansion cavity from contraction chamber, combustion gas is introduced uniformly expansion cavity at place, Wen Qiuli waist hole and is mixed.
2, the gas joint that the present invention settles on induction tunnel communicates with negative pressure cavity; In gas joint, be provided with throttling valve core, the size of adjusting joint discharge orifice, can change thermic load, has deducted gas nozzle.
3, the present invention is provided with blast switch at place, high pressure air port, has improved security and the controllability of burner in combustion process.
4, the present invention is equipped with air register at air inlet place, increases the amplitude of accommodation of air quantity.
