Biogas flows into from Gas Pipe, and from a point valve ejection after flowing through the boosting of boosting cylinder section, air is poured into from air hose and flowed out through rotating guide card, and biogas and air mixing after-combustion, sufficient combustion, efficiency of combustion is high.
The outer setting of described air duct has adpting flange.
Described point valve and Gas Pipe axial line are 20 ° of angles.
In two described circle point valves, inner ring is furnished with 8 points of valves, and outer ring is furnished with 16 points of valves.
Described point valve length is at about 40mm.
The present invention has the following advantages:
Electronic ignition of the present invention, is undertaken lighting a fire by combustor standard, purges, Load Regulation, and biogas have passed through a supercharging, and the biogas after supercharging is separated by nozzle, ensures that the pressure head of biogas is stablized, flow equalization, ensures diameter and the length of flame.If flame instability, flame detecting device can produce signal alarm and shut down.
The present invention is provided with rotation guide card, and rotary cutting aweather ensures combustion power and after-flame.
The present invention's burning cmpletely, once pass through, and the thermal efficiency is high by type approval test.
Flameholding of the present invention, ensures that the heating equipments such as boiler meet burden requirement.
Improve the flow velocity of valve by arranging pressurization cylinder, configure rational air distribution and make adjustment than increasing, load regulation range is 40 ~ 110%, substantially meets user's requirement.
The purity requirement of online biogas can be adapted to, do not need to do any process, can not secondary pollution be produced.
