Description

Fuel-air ratio auto-adjusting burner
The utility model be a kind of be that fuel adopts gravity-flow ventilation with gas, the combustion gas-AIR Proportional that is used on the heating furnace is regulated the combustion energy saving device automatically.
In oil and chemical industry, be the heating furnace of all kinds gravity-flow ventilation of fuel with gas, manually commonly used or two kinds of control method fuel metering burnings of instrument required air quantity.And manual adjustments air door degree of regulation is poor, can not and regulate air capacity at any time with the gas fuel pressure variation again simultaneously, and the air capacity when causing fuel combustion is not enough or superfluous (general coefficient of excess air a reaches 1.5~2.0).Cause fuel can not completing combustion or excess air take away a large amount of heats, reduced the heating furnace operating thermal efficiency.Though instrument control guarantees the ratio of fuel and air and regulates automatically that investment increases, complicated operation, is difficult for administering and maintaining.Especially how in the open air use under the open-air atmosphere with heating furnace in the oil field, does not generally control excess air, as long as guarantee that adequate ventilation is arranged, causes heater efficiency to reduce, and wastes fuel.The oil field is being moisture natural gas with the fuel used major part of heating furnace in addition, because the winter environment temperature is low, causes control instrument to freeze to control malfunctioning, causes combustion gas and air not to regulate by automatic ratio.The engineering consulting company in U.S. Mexico state carries out combustion gas-AIR Proportional adjusting test since in 1981.Utilize orifice plate of burning line pressure operation of burner to move air throttle in the special-shaped chamber, the flow through excess air of fire tube of control reaches combustion gas-AIR Proportional and regulates.But because oil field heating furnace and adjusting thereof are partly, be in the field extreme environment,, influence heater efficiency in this environment orifice plate operation governor motion poor sensitivity.
Comprehensive above-mentioned deficiency changes greatly at the peculiar operating load of oil field heating furnace, and the ratio of combustion gas and air is difficult for grasping the actual features of open-air open-air condition difference.It is a kind of simple in structure that the utility model provides, and the gas-air ratio is regulated reliable and stable, and excess air is controlled between 1.05 to 1.2, and the higher combustion gas-AIR Proportional of degree of regulation is regulated burner automatically.
The utility model relates to the improvement invention that a kind of combustion gas-AIR Proportional is regulated burner automatically.Promptly regulate on the basis of burner in existing ratio, to gas-air ratio regulating system, combustion system is improved, and has constituted the technical characterictic of Fig. 1, Fig. 2.
Technical essential of the present utility model is that structure that this combustion gas-AIR Proportional regulates burner automatically as shown in Figure 1.It is made up of fuel control valve (1), pressure balance gas bag (2), pressure guiding pipe (3), pneumatic actuator (4), air regulating board (5), special-shaped inlet air plenum (6), atmospheric burner (7).Wherein fuel control valve (1), pressure balance gas bag (2), pneumatic actuator (4), air regulating board (5) and atmospheric burner (7) all are to connect and compose the adjusting combustion system by pipeline.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1, combustion gas-AIR Proportional are regulated the burner principle assumption diagram automatically.
Accompanying drawing 2, atmospheric burner structure cutaway view.
Accompanying drawing 3, shower nozzle (8) is to view.
Accompanying drawing 4, burner (10) cutaway view.
Accompanying drawing 1 has provided the utility model, the general principles structure chart of combustion gas-AIR Proportional automatic regulating system and atmospheric burner combustion system.Pressure balance gas bag (2) is hollow Cylinder, the buffer board of its inwall welding 1 to 2 overpressure balance gas bag (2) center line, and buffer board plays the voltage stabilization and current stabilization effect to the pressure pulse of fuel gas.Pressure balance gas bag (2) both ends of the surface respectively have shape hole, a garden, and its exit end face is communicated with atmospheric burner (7) by the side pipeline that passes special-shaped inlet air plenum (6), and inlet end face is communicated with fuel control valve (1) by pipeline.Fuel control valve (1) is a needle valve, and this valve can be according to heating furnace Load Regulation fuel quantity.Pressure guiding pipe (3) one ends are communicated with pressure balance gas bag (2) side, and the other end is communicated with pneumatic actuator (4) right side.Pneumatic actuator (4) is a membrane structure.The size of film and thickness based on fuel atmospheric pressure scope are chosen.Air regulating board (5) is the garden shape thin plate that the center is furnished with pull bar, and radially there is the annular gap of 2-3 millimeter this thin plate and special-shaped inlet air plenum (6) right part, and is connected with pneumatic actuator (4) left part.Abnormity inlet air plenum (6) is the special-shaped cavity cone of a both ends open, and the left part is connected with body of heater.Pneumatic actuator (4), air regulating board (5), special-shaped inlet air plenum (6), atmospheric burner (7) locus are same axis.
Accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 have provided the structure cutaway view of the utility model burner (7).
Atmospheric burner after the improvement (7) mainly is made up of shower nozzle (8), mixing drum (12) and burner (10) three parts.The structure of shower nozzle (8) is that cross is arranged, and has the dismountable nozzle (9) more than 4, and nozzle quantity the best is 4-8, is evenly distributed with dismountable spinning disk (11) more than 3 in the burner (10), and spinning disk quantity the best is the 6-10 sheet.This spinning disk becomes 30 ° of-45 ° of helical angles with the axis of atmospheric burner (7).
When combustion gas is sprayed by the nozzle (9) on the shower nozzle (8), mix with primary air.Owing to adopt a plurality of nozzles, improved combustion gas and primary air mixed effect.Mixed combustion gas becomes rotational flow state ejection burner (10) through spinning disk (11), and this has just further strengthened mixing of combustion gas and auxiliary air.
The self-regulating principles illustrated of the utility model combustion gas-AIR Proportional is as follows.When fuel gas enters the pressure balance gas bag (2) that has buffer board through fuel control valve (1), obtain cushioning voltage stabilizing, because pressure guiding pipe (3) is communicated with pneumatic actuator (4), guarantee the pressure balance of pressure balance gas bag (2) and pneumatic actuator (4).Pneumatic actuator (4) affects the air regulating board (5) in cavity cone abnormity inlet air plenum (6) to make back and forth movement by the gaseous-pressure effect.Combustion air is inhaled into from the annular space between special-shaped inlet air plenum (6) and the air regulating board (5) by negative pressure in the burner hearth, finishes the wind effect of transferring.When gaseous-pressure changes, act on also synchronous the changing of pressure on the pneumatic actuator, cause air regulating board to produce displacement at special-shaped air intake indoor location, radial ringed gap also changes thereupon, enter also corresponding the changing of air capacity in the burner hearth, thereby the ratio that has realized combustion gas-air capacity is regulated automatically.
After the utility model fuel-air ratio auto-adjusting burner adopts said structure, produce following effect through the production run examination.
1, combustion gas and auxiliary air mixed effect have been improved.
2, coefficient of excess air is controlled between 1.05~1.2.
3, the thermal efficiency improves 7~10%.
4, manufacturing cost is regulated combustion gas-air automatic ratio burner than existing instrument and is reduced investment outlay 70~80%.
