Description

The gas burner that premixed is adjustable
Technical field
What the present invention relates to is burner, particularly a kind of adjustable gas burner of premixed that is used for natural gas, Device in Gas, coal gas, biogas.
Background technology
Power plant boiler, various Industrial Boilers, civil heating boiler, various heating furnace, various light industry kiln, converter all need use burner, and this burner is a fuel with natural gas, Device in Gas, coal gas or biogas usually.During work, need strict heating curve protection body of heater and guarantee the product quality in the stove.The nozzle of the gas burner that uses at present, its design are to design according to the maximum that gets into combustion gas, have only a specification.In actual motion, influenced by gaseous-pressure, the gas quantity of burner ejection is extremely unstable, the time little, the time big, combustion gas discharge rate hour can not satisfy the process curve requirement, difficult technique control, efficiency of combustion is bad, and big to the burner damage.During the little fire of giant spray, because gas quantity is not enough, spray not go out and reduce internal heat, fire can only burn at nozzle nearby, time one length, and the nozzle easy burn-out promptly influences the thermal efficiency, fragile again nozzle.
Summary of the invention
The objective of the invention is provides a kind of premixed adjustable gas burner to the problems referred to above, and gas quantity, the air capacity amount of actual needs when producing is adjusted ejection burning after the premixed, improves the thermal efficiency.
The present invention realizes through following technical scheme: the gas burner that this premixed is adjustable is provided with small nozzle Gas Pipe, giant Gas Pipe; The small nozzle Gas Pipe is positioned at the burner center; The giant Gas Pipe is enclosed within the outside of small nozzle Gas Pipe; Between small nozzle Gas Pipe and the giant Gas Pipe and between giant Gas Pipe and the burner outer wall air duct is arranged, the front end side of small nozzle Gas Pipe, giant Gas Pipe all has gas jet orifice; The front and back ends of small nozzle Gas Pipe, giant Gas Pipe is equipped with closure plate respectively, and the rear end is connected through fuel gas inlet pipe, gas control valve and combustion gas respectively; The air swirl sheet is housed respectively in the air duct, and its rear end is equipped with closure plate respectively, and the air duct rear end is connected through air intake pipe, air shut-off valve and compress wind respectively.
Adopt the good effect of technique scheme: the gas quantity and the equal scalable of air distribution amount of the gas burner ejection that this premixed is adjustable; Needed gas quantity, air capacity spray after adjusting premixed during by work; The gas quantity hour of ejection; Starting small nozzle Gas Pipe, starting giant Gas Pipe did not influence heating curve when the gas quantity that need spray was big; Ejection in the rotation in combustion gas and the air distribution spray gun makes combustion gas and air distribution obtain reinforcement when mixing, forms ejection in the rotation in spray gun behind the mist, and burning velocity is fast, and flame temperature is high, has improved the thermal efficiency, and minimizing generation exhaust gas volumn reduces production costs.
