Abstract
The utility model provides a gas combustion burner. The gas combustion burner comprises a tubular body, wherein a clapboard is radially arranged in the inner chamber of the tubular body along the inner chamber and divides the inner chamber of the tubular body into a gas mixing chamber and an air buffer chamber; and an air flow guide tube is coaxially arranged in the gas mixing chamber, the tail end of the air flow guide tube penetrates the clapboard and is hermetically communicated with the air buffer chamber, and air flow dividing ports are formed in the side wall of the air flow guide tube and are uniformly distributed in the circumferential direction of the flow guide tube. The burner adopting the structure has the benefits that the mixing of gas and air is quick and complete, the combustion flame is short, and the combustion efficiency is higher; and as the air buffer chamber and the gas mixing chamber are formed, while the low-pressure coal gas is entrained and mixed with the high-pressure air, the pressure in the burner can be kept stable, and the risk of tampering caused by low jet speed of the low-pressure coal gas at a nozzle is avoided, so that the use is safe.

During use; Combustion gas (like coal gas) gets into the gas hybrid chamber from fuel gas inlet; Air gets into air buffer memory chamber by air intlet earlier; The airflow duct of flowing through is again got in the gas hybrid chamber and combustion gas mixing by the equally distributed diffluence pass of airflow duct sidewall, and mist is in the openend burning of tubular body.Under the utility model structure, combustion gas and air mixing velocity are fast and fully, combustion flame is short; Efficiency of combustion is higher; Because air buffer memory chamber and gas hybrid chamber are set, make when low-pressure gas is entrainmented mixing by pressure-air that simultaneously the pressure in the burner can keep stable;, not safe in utilization because of the low danger that causes tempering of jet velocity of low-pressure coal gas at the spout place.
Preferably; The outer surface of airflow duct forms fins set along self circumferentially evenly being set up in parallel fin; Said fin is fixedly connected with airflow duct along hand of helix; The individual pen length that is shorter in length than said helix of said fin, fin is obliquely installed with the mode of top near the air conducting tube outer surface.Through fin is set, air-flow is evenly separated, and formed swirling eddy, the gas mixing velocity is faster, and mixed effect is better.The utility model forms spiral fin to the no specific (special) requirements of pitch size of helix as long as fin is installed along the helix scheme, and gas is got final product around the mobile swirling eddy that forms of fin.
Preferably, said fins set is two groups, and two ends and rotation direction that two groups of fins are divided into airflow duct are opposite.Said rotation direction is meant that on the contrary the hand of spiral of one group of fin is opposite with another hand of spiral of organizing fin; Two groups of fin rotation directions are opposite, make air and coal gas in the gas hybrid chamber, form turbulent flow, further improve the gas mixed effect.
Preferably, circumferentially evenly be provided for being communicated with the perforation in gas hybrid chamber and air buffer memory chamber on the dividing plate around airflow duct, be convenient to pressure-air and in the gas hybrid chamber, spread, coal gas and air utilization ratio are higher.
Preferably, said fuel gas inlet and air intlet axially are set up in parallel along tubular body.
Preferably, dividing plate and airflow duct are processed one, and sound construction is easy to make.
Need to prove; The said helix of the utility model is meant with the tubular body axis to be the helix of center line; Said finned length is meant that fin launches the length of back along self longitudinal centre line; The individual pen length of said helix is meant the length after the individual pen helix launches, and said tail end is meant when using the end away from the mixture combustion mouth.
The beneficial effect of the utility model:
In sum, than prior art, the utility model is owing to adopted technique scheme; Make that combustion gas and air mixing velocity are fast and fully, combustion flame is short, efficiency of combustion is higher; Simultaneously because air buffer memory chamber and gas hybrid chamber are set; Make when low-pressure gas is entrainmented mixing by pressure-air that the pressure in the burner can keep stable, not because of the low danger that causes tempering of jet velocity at the spout place of low-pressure coal gas; Safe in utilization, overcome the deficiency that simple premixed and simple diffusion type burns in the prior art.
