Pressure cylinder is conically shaped, and the larger diameter end of pressurization cylinder is fixedly arranged on the inner side of circular shrouding, and pressurization cylinder is coaxially disposed with Gas Pipe, supercharging
Cylinder is gradually reduced along direction external diameter from front to back, so that the section face that combustion gas combustion gas during onwards transmission passes through
Product is gradually reduced, so that the speed that the pressure, raising combustion gas beneficial to increase combustion gas spray from point valve, described air hose is by edge
The bellows of the major diameter being sequentially connected from rear to preceding direction and the air duct of minor diameter are constituted, and air intlet is provided with bellows,
The front end of air duct is air outlet, and rotation guide card, igniter and flame are provided between the front end of air duct and the outer wall of Gas Pipe
Detection means passes through air hose and extends to the front end of air hose, and the rear end of igniter is provided with liquefied gas or natural gas enters
Mouthful, for being input into liquefied gas or natural gas, light the biogas sprayed from Gas Pipe.
Biogas are flowed into from Gas Pipe, are sprayed from point valve after the boosted cylinder section boosting of cocurrent, and air falls from air hose
Enter and the outflow of rotated guide card, biogas and air mixing after-combustion, burning is abundant, high combustion efficiency.
The outside of described air duct is provided with adpting flange.
Described point valve is in 20 ° of angles with combustion gas tube axis line.
In two described circle point valves, inner ring is disposed with 8 points of valves, and outer ring is disposed with 16 points of valves.
Described point valve length is in 40mm or so.
The present invention has advantages below：
Electronic ignition of the present invention, is lighted a fire by combustor standard, is purged, Load Regulation, and biogas have passed through once
Supercharging, the biogas after supercharging are separated by nozzle, it is ensured that the pressure head stabilization of biogas, flow equalization, it is ensured that flame
Diameter and length.If flame instability, flame detecting device can produce signal alarm and shut down.
The present invention is provided with rotation guide card, and rotation Tangential Wind ensures combustion power and after-flame.
Cmpletely, type approval test once passes through, and the thermal efficiency is high for present invention burning.
Flameholding of the present invention, it is ensured that the heating equipment such as boiler meets burden requirement.
The flow velocity of valve is improved by setting pressurization cylinder, configuring rational air distribution makes regulation than increase, load regulation range
It is 40 ~ 110%, substantially meets user's requirement.
The purity requirement of online biogas is suitable for, is not required to do any treatment, secondary pollution will not be produced.
