Abstract
The invention discloses a ceramic secondary mixed combustion burner which comprises a burner core, wherein a cylinder is sleeved outside the burner core, one end of the cylinder is connected with a furnace wall, the cylinder is internally provided with a location disk which is used for fixing the burner core between the location disk and the furnace wall, the other end of the cylinder is provided with a nozzle regulator and a compressed air supply pipe, and the furnace wall is provided with a combustion air main pipe. The invention has the beneficial effects that the ceramic secondary mixed combustion burner can be used in severe environments with air source high temperature and low pressure as well as no clean, has a simple structure, and is not easy to block. Because the ceramic burner core is adopted, the ceramic secondary mixed combustion burner has long service life and small deformation and is easy to accurately regulate fuel feeding quantity.
Description
Technical field
The present invention relates to a kind of Industrial Stoves apparatus, especially a kind of porcelain secondary mixing combination burning mouth.
Background technology
The big Industrial Stoves burner of heating load can't adapt to the low environment of bleed pressure at present.Force before the burning, source of the gas is carried out supercharging with mechanical means.When source of the gas belongs to non-clean high-temperature fuel gas, when the direct supercharging of mechanical means was difficult to implement, bleed pressure is low just to become an impassable obstacle.Keep outside of the door to making a large amount of Industrial Stoves gas generator that operation cost is low.
Summary of the invention
The objective of the invention is to design and a kind ofly can adapt to the gas source temperature height, pressure is low, the Industrial Stoves burner of cleanliness factor difference.
Technical scheme of the present invention is: a kind of porcelain secondary mixing combination burning mouth; This burner comprises the mouth heart, and the mouth heart is with tube outward, and an end of tube is connected with the furnace wall; Be provided with positioning disk in the tube; Fixedly the mouth heart is in tube between positioning disk and the furnace wall for positioning disk, and the other end of tube is established shower nozzle adjuster and compressed air supply pipe, and the furnace wall is provided with the combustion air person in charge.
The invention has the advantages that: can be at the source of the gas high-temperature, low-pressure uses under the non-cleaning and the adverse circumstances of depositing.Simple in structure, be difficult for stopping up.Owing to adopt the porcelain mouth heart, long service life be out of shape for a short time, and the combustion gas amount of sending into is regulated precisely conveniently.
Description of drawings
Fig. 1 is a porcelain secondary mixing combination burning mouth sketch map of the present invention;
Fig. 2 is a porcelain secondary mixing combination burning mouth structure sketch map of the present invention.
The specific embodiment
A kind of porcelain secondary mixing combination burning mouth, this burner comprises the porcelain mouth heart 1, the mouth heart is with tube 2 outward, an end of tube is connected with furnace wall 3, is provided with positioning disk 4 in tin, positioning disk fixedly the mouth heart in tube between positioning disk and the furnace wall (being equivalent to the plate washer effect).The other end of tube is established shower nozzle adjuster 5 and compressed air supply pipe 6.The furnace wall is provided with combustion air and is responsible for 7.
This structure can form negative pressure, can regulate the amount of sending into of combustion gas very easily.For implementing dynamic timely adjustment the basis is provided.
Principle according to hydrodynamics continuity law and Bernoulli's theorem " when fluid flowed in a pipeline, the local pressure that flow velocity is big was little, and the local pressure that flow velocity is little is big " is a theoretical foundation.Burner is designed to the secondary mixed structure.Promptly form low-pressure area at the converging portion of the porcelain mouth heart with high velocity air.Force combustion gas to get into low-pressure area and carry out mixing the first time with air.Mixed combustion gas gets into diffuser through converging portion at a high speed, and flow velocity reduces, and pressure increases.Because it is little to mix the combustion air total amount of injecting for the first time, is not enough to abundant burning.When getting into second mixed zone, because combustion gas has certain kinetic energy, to mix more fully with combustion air, continuity is better.Help improving combustion stability.When regulating the relative position and adjusting compressed-air actuated pressure, the send into amount that can very easily regulate combustion gas of compressed-air atomizer in the region of convergence.For implementing dynamic timely adjustment the basis is provided.
Porcelain secondary mixing combination burning mouth is to low this severe rugged environment design of bleed pressure.Require apolegamy different model (diameter) burner according to the heat supply total amount, directly insert the gas pipeline and the combustion air of kiln and be responsible for, matched air compressor, insert compressed air.Adjust air pressure and nozzle location during operation in good time, guarantee to satisfy the demand of heat total amount.
Burner frame for movement is main body with the steel casing, in the inboard according to the length of the burner porcelain mouth heart positioning disk is set, in order to the fixing mouth heart.The upper end is provided with the steel top cover and is fixed on the shell upper end with screw rod, and the center is provided with nozzle secured adjusted device.The lower end is responsible for screw rod and combustion air and is linked.
Claims (1)
