The present invention relates to a kind of direct spray type gas burner, be applicable to all kinds of combustion gas tools, kiln and boiler, be particularly useful for the occasion of boundling heating.The combustion gas of using comprises liquefied petroleum gas, natural gas, artificial coal gas and other artificial fuel gas etc.Because its structure and combustion system are different from burners such as diffusion type, air suspended type and blowing-type, its combustion gas directly is sprayed onto main fire-fighting interruption-forming injecting type burning by main fire-fighting mouth without Venturi tube and mixing chamber, so be referred to as direct spray type gas burner.At present, the diffusion flame burner combustion efficiency is not good enough, few using; The atmospheric burner fire hole disperses, and is lower to the less thermal efficiency that is heated during this heating; Air blast burner then needs air blast, compressed air line and nozzle and mixing chamber etc., and is comparatively complicated, the cost height, and it is also difficult to regulate firepower on a large scale.These shortcomings seem more outstanding on the small gas tool.
The purpose of this invention is to provide a kind of simple, efficient, safety, firepower is concentrated gas burner.Firepower should be able to be regulated in gamut continuously, and this burner also has the characteristics of electromechanical integration, the automatic resume combustion of should be able to lighting a fire automatically, stop working.Flame-out when meeting accident, stop the supple of gas or steam, overtemperature, anoxic and when shaking doughtily, should carry out fast that safety is held one's breath and sound and light alarm.
Purpose of the present invention realizes by following scheme:
The place ahead in main fire-fighting mouth ejection combustion gas, an auxilliary ignition combustor is set, the combustion gas that main fire-fighting goes out is lighted by auxilliary fire, main fire-fighting mouth is a needle-valve, its blast tube (8) slide inside assembling soft magnetic bodies tap web (5), the outside slidable fit permanent magnet (4) then tap web (5) just can move by magneticaction along with moving of permanent magnet (4), the sectional area of mobile change blast tube (8) gas outlet by tap web (5), constitute the structure of forward type valve regulated thermic load, make combustion gas flow to gas outlet from fuel gas inlet, direct injection is come out.
Include the burner (9) of flame ion probe (10), igniting needle (2), umbrella crown (3) and auxilliary ignition combustor in the direct spray type gas burner; Flame ion probe (10) and igniting needle (2) are fixed by the umbrella crown (3) and the bottom surface of the burner (9) of auxilliary ignition combustor.
The crater of the auxilliary ignition combustor of direct spray type gas burner (11) is the annular slot of sealing, and its flame is continuous annular.
The configurable little process chip of direct spray type gas burner, safety valve, firing circuit, sound light alarming circuit, digital display circuit, over-temperature sensor, hypoxia sensor, environment temperature sensor, seismic sensor and actuating motor, gear and tooth bar are formed intelligent electromechanical type buner system, wherein, overtemperature, anoxic and environment temperature sensor are thermistors, and seismic sensor SK is a compound pendulum, an electric contact K3 is arranged on its pendulum, when earthquake took place more than 6 grades, ground was taken in its contact.
The control of system is core with little process chip, and its input quantity has: desired temperature, equipment task time setting value, flame ion signal, overtemperature, anoxic, environment temperature and seismic signal; The system that exports to after these input quantities are judged through the processing of little process chip and logic is with the lower part: when accident extinguishing occurring, provide high-voltage pulse through firing circuit to igniting needle, finish automatic ignition and resume combustion; If can not resume combustion in 3 seconds, just stop sparking and drive safety valve holding one's breath, simultaneously sound and light alarm; Show that to temperature and time charactron provides the decoding driving data, change through pattern, then show instantaneous value: when controlled temperature has error, little process chip provides rotating voltage through " H " switch to actuating motor M, after slowing down, drive tooth bar (7) and move, finish firepower and adjust automatically by gear (16); Little process chip also can be sent signal to drive circuit when overtemperature, anoxic and earthquake, drive the actuating motor rotating, cuts off source of the gas and sound and light alarm by safety valve again; Below all are Electronic Control, so response fast.
The body of direct spray type gas burner is made up of main ignition combustor and auxilliary ignition combustor.The similar needle-valve of its main fire-fighting mouth, the blast tube the inside is sliding is adorning a soft magnetic bodies tap web, changes their relative position, and the area of tap web stopped nozzles pipe just changes, just change the effective area of blast tube outlet, thereby can in whole firepower scope, regulate the firepower size.A high magnetic force permanent magnet is being overlapped in the blast tube outside, then forms magnetic drives between tap web and the magnet, and the advantage of magnetic drives is not have gas leakage during transmission extremely.Permanent magnet is just at the end of combustion gas ejection, thus after combustion gas is subjected to magnetization, not loss by the road, ejection helps abundant burning immediately.Main fire-fighting mouth places main fire-fighting mouth the place ahead, and the size of distance is decided by the size of firepower.This main fire-fighting mouth is less to the gaseous-pressure loss when being adjusted to little firepower, even the pressure in little when fire height during on the contrary than big fire.Like this, can overcome drawback when turning fire down with steam supply valve.Be that this method fuel gas injection kinetic energy when little fire is bigger, stronger to the injection power of air, thus can guarantee abundant burning.This is an important feature.As mentioned above, the present invention need not Venturi tube and mixing tube, and like this, combustion gas is the kinetic energy loss minimum in the direct injection process, and promptly injection power is the strongest.So that (being low to moderate 0.002MPa as the liquefied petroleum atmospheric pressure) under low gas pressure power still has enough injection power.This is second characteristic.These two characteristics all are not lose the kinetic energy of gas-flow as far as possible, have guaranteed that direct spray type gas burner also has good combustibility under low gaseous-pressure.Flame is the basket purple in whole firepower scope, even full purple.
Auxilliary ignition combustor is an air suspended type, but crater is the closed loop clearance type.And its duration and degree of heating inner chamber is exactly main crater.Combustion gas directly is sprayed onto outside the main crater, is assisted the auxilliary fire of ignition combustor and lights.Because the crater of auxilliary ignition combustor is the circumferential weld of sealing,, auxilliary like this fire must be the ring-shaped continuous fire, thus it surrounds main fire fully, does not fly away from so can guarantee main fire to be lighted fully.The ring-shaped continuous fire has very high electricity leads, so can guarantee the high sensitivity that flame ion is surveyed, guarantees the reliability of pulse sparking and automatic resume combustion.
On the auxilliary ignition combustor flame ion probe and igniting needle are housed.They are fixed under the umbrella crown of insulation, and waterproof anti-soil guarantees insulating properties.
Can reflect for information about part fixedly overtemperature, anoxic, earthquake and environment temperature sensor, they and little process chip, control circuit, actuating motor and safety valve are supporting, form the direct spray type gas burner of electromechanical integration.
Practical function of the present invention: direct spray type gas burner saves the flame that add-on components such as air blast just can obtain the blowing type gas burner, it is about 50% that product cost reduces, and its flame is basket purple, sufficient combustion, the flue gas nuisance reduces, CO content about 0.02%.The thermal efficiency improves nearly 20%.Firepower is fierce, is the boundling shape, is used for food stalls and restaurant and does the big fire kitchen range, and effect is fine.The result that the direct spray type gas burner main body combines with microelectronic circuit makes it to have the characteristics of electromechanical integration: igniting automatically, and flame-out automatic resume combustion, multiple protection fast and safely, so that firepower is controlled automatically.
