The feature of this burner is: 1) fuel and oxidant inject fast mixing combustion in burner from the tangential finedraw entrance being distributed in circumference respectively, these tangential finedraw entrances are distributed in combustion chamber internal diameter circumferentially, air intake duct is curved, effectively can prevent the generation of tempering phenomenon.2) the arc air intake duct on the inside diameter hoop of combustion chamber is utilized, the gas flowed at a high speed is pushed ahead along locular wall and tube wall High Rotation Speed, this gas-dynamic behaviour makes high density unreacted fuel gas be close on the inwall of eddy flow quartz glass tube, form the gas membrane that one deck density is comparatively large, temperature is lower, wrap the flame region of tubular body, contained the conduction of heat between flame and wall, effectively reduce the loss of calory burning, heat utilization efficiency is high.Simultaneously this layer of air film has also cut off flame and has contacted with the direct of burner wall; reduce the wall surface temperature of burner; effective protective effect is served to burner; extend the service life of burner; expand the scope of selecting material of burner, for the engineer applied of burner has laid solid material base with actual popularization.3) by changing the width of adjustment block and the gap width with eddy flow frame thereof, burner inlet flow velocity can be changed flexibly, thus change the mixed effect of fuel and oxidant, the generation of nitrogen oxide and carbon monoxide can be reduced, dusty gas discharge is few, has advantage that is energy-conservation and that reduce discharging.4) can form stable laminar flow tubular flame, tubular flame is even, and good mixing effect, efficiency of utilization is high, can be widely used in daily life, industrial technology.
According to tangential inlet mixing tubulose flame burner of the present invention, there is following beneficial effect:
1. fuel gas of the present invention and oxidant inject burner respectively from the tangential finedraw entrance being distributed in circumference combustion chamber in mixed combustion, the generation that tempering is even exploded can be prevented when flow velocity is lower or oxygen concentration is higher;
2. the present invention utilizes gas-dynamic behaviour on the inwall of quartz glass tube 4, form the unburned gas film that one deck density is comparatively large, temperature is lower, wrap the flame region of quartz glass tube 4 inside, decrease the heat trnasfer between flame and wall, effectively decrease the loss of heat, heat utilization efficiency is high;
3. the present invention is due to its swirling two-phase flows characteristic, can available protecting burner wall, prevents ablation, the service life of prolonging combustion device;
4. the present invention can be used for mixing and premixed two kinds of different combustion cases, and equal energy formation temperature is evenly distributed, the laminar flow tubular flame of safety and stability; Mixed combustion effectively can prevent the generation of tempering phenomenon, has good security reliability;
5. the present invention is by changing the thickness of adjustment block 1 or increasing the number of adjustment block 1, can change the mixed effect of fuel and oxidant, make burning more abundant;
6. the present invention effectively can reclaim tail gas under pure oxygen condition, reduces the discharge of carbon dioxide, decreases the discharge of nitrogen oxide simultaneously, have effect of energy-saving and emission-reduction.
