Have for installing hydrocone type air atomizer spray nozzle nozzle holder, for temperature sensor mounted block temperature sensor and be used for
The igniting obturating plug of igniter, the central axis of air inlet and the central axis upright of ignition cylinder are installed.Enter combustion in this way
Tail gas in burner would not directly be washed into burned flame, and then reduce flame-out probability.
As a preferred solution of the present invention, burner is made of stainless steel material.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, fuel oil and mixed is impacted by compressed air, the compressed air of high pressure impacts fuel oil, forms more body
The contact area of the more tiny but bigger surface area atomization form of product, such fuel oil and oxygen increases, and keeps burning more sufficiently more acute
It is strong, improve efficiency of combustion in this way, also prevent because burn acutely caused by be easy flame-out problem；
2, simultaneously by compressed air by nozzle jelly and carbon particle wash open, avoid spray nozzle clogging the problem of
