Sparking line 7 is respectively equipped in detection hole 45.One sparking line is connect with sparking hole and burner lid respectively, another sparking line difference
It is connect with fire defector hole and burner lid.When the sparking line top on sparking hole connects igniter, end just issues electric spark, point
Fire combustion gas.Another sparking line encounter flame will feedback signal to igniter, igniter will flashing light, at this moment just known combustion gas
It lights.Whether can also be lighted flame from seeing in flint glass hole.
Combustion gas and combustion air need certain proportion mixing that could burn, if combustion air is insufficient, combustion gas is excessive, portion
Divide combustion gas just to form undesirable flue gas without full combustion, causes environmental protection not up to standard.To be sufficiently mixed combustion gas with combustion air
The gross area ratio of burning, the fuel gas hole 310 and combustion-supporting hole is 1:(5.5-7.5), the pressure ratio of the combustion gas and combustion air is
1:(0.5-1).Combustion gas and combustion air can be made to be sufficiently mixed combustion it should be noted that area ratio and pressure ratio must limit just simultaneously
It burns.The pressure of combustion gas and combustion air can be adjusted by the size of the combustion air and combustion gas that are passed through, and can pass through pressure detecting
First 61 pressure size both to detect.There are two pressure detecting heads 61, a detection gaseous-pressure, another detection combustion air
Pressure.
It should be noted that the gross area of the combustion-supporting hole and fuel gas hole 310 ratio can for 1:5.5,1:6,1:6.5,1:7 or
The pressure ratio of 1:7.5, the combustion gas and combustion air can be 1:0.5,1:0.6,1:0.7,1:0.8,1:0.9 or 1:1.
Clash on disk 4 by the combustion air of first annular combustion-supporting hole 41 with after 31 top high velocity impact of combustion gas nozzle, air-flow
By the flowing that unsteadiness is random, the air-flow and combustion gas package that the combustion air of the second annular combustion-supporting hole 42 flows unsteadiness at random,
It can promote the exchange of burnt gas and unburned gas near flame front, expand flame front surface area, to improve flame propagation
Rate, is also beneficial to the burning that is sufficiently mixed of air and combustion gas, burning sufficiently, energy conservation and environmental protection, the thermal efficiency it is high, cost performance is high, peace
It is complete reliable.In addition, forming negative pressure in burning head-on collision mechanism, a part of high speed ejection air-flow can be flowed back by negative pressure covers returning on 5
Discharge orifice 51, reflowable to the secondary mixed firinor fuel burning of progress in burning head-on collision mechanism, energy conservation and environmental protection makes the cost performance of high velocity burner more
It is high.
