Description
Technical field
The present invention mainly discloses a kind of burner, espespecially utilizes guiding device and reaches the gas combustion device improving flame visibility and have security.
Background technology
Traditional Space heater is generally divided into electricity consumption and the large class of non-electrical two.Two kinds of devices respectively have its pluses and minuses, generally speaking, can produce larger heat at short notice with the aircondition of combustion system heating and not increase the power load of regional power system.Typical commercial heating warm-keeping facility has electrical equipment to heat and fireplace (Fireplace), stove (Firepits) heat two kinds, uses the indoor air conditioner quantity of combustion system heating not second to using electrically heated aircondition in high latitude area.It is outdoor if flower garden and balcony heater are then based on combustion heating.Because electrical equipment heater device is because configuring high capacity circuit and heating pipe line system, the price of its equipment own is high and must use power supply input energy sources, need consider high load currents, and therefore except corporate facility is distinguished public room and often adopted, user is few at home.The general heating-warming arrangement at home of middle high latitudes, especially high latitude country all adopts stove burning heater more, gets that it is easy to use and whole cost is cheaper.And combustion heating furnace is common with timber (cordwood), fuel slug (pellet) or using gas (propane) natural gas (natural gas) as fuel inside and outside conventional chamber.In recent years, due to the consideration of Environmental Factors, compare with the efficiency of combustion of timber, fuel slug and natural gas and CO2 emissions, natural gas is the cleanest energy, and its carbon emission amount obtaining units of heat is minimum.The lower use timber of comparing is considered to be fuel more not environmentally gradually.Sold for 2012, the fireplace that North America more than 70 percent is newly sold adopts natural gas as fuel.But development in recent years, flame combustion apparatus is singly just simple heating not, and often have the construction of decoration and atmosphere concurrently, therefore, the high-effect burner with stressing flame esthetics modelling of tool, commercially comes into one's own gradually simultaneously.
Current gas flame burner controls or changes flame profile mode greatly mainly with change nozzle distribution mode, or adds that Transparent shielding is as water conservancy diversion by device, utilizes stack effect importing outer gas stream control or change the modes such as flame profile more common.But vortex moulding flame is except making generation and rotating, and flame only upwards can extend in the mode of line, cannot laterally to change with the direction in face.And having common flame dimension-limited system, easy accumulation gas, the high heat of device accumulation waits the shortcoming used.Main cause is, though shielding can shaded portions external air flow, avoids flame directly to affect by ambient windstream, makes the specific flame moulding of maintenance.But, adopt this kind of semienclosed shielding also along with having atmosphere draught-free and overheated shortcoming.Need shielding function be provided owing to generally shielding, generally only top and side opening for air circulation.If opening crosses the major function that conference loses shield gas flow; Though if the effect that too small openings can provide preferably air-flow to cover, the heat that produces during burning and waste gas also can be caused not easily to scatter and disappear.If if can fray-out of flame be caused when cannot supplement enough fresh airs in time in shielding, or produce black smoke even toxic gas because of incomplete combustion.Meanwhile, if the rate of air circulation in shielding is inadequate, just effective heat radiation cannot be reached.The heat history produced during burning is when the heat-sinking capability that device can reach cannot reach balance, and the time of use is longer will make the temperature of device entirety higher.
If do not use Transparent shielding water conservancy diversion, the mode of spraying with nozzle is then subject to ambient windstream impact, and flame is not controlled, and the change of flame type is extremely limited.But not above-mentioned two kinds change the common mode of flame profile, more specifically mode is then with electromagnetism ACTIVE CONTROL flame profile, but it is expensive with such device complex structure, and be only limitted to the less flame of control combustion scale at present, due to unshielded, be subject to ambient windstream impact equally, and be only limitted to the experimental stage at present, there is no commercial prod.
Please refer to No. 7097448th, U.S. Patent number " VORTEX TYPE GAS LAMP " Patent Case, its gas lamp (gas lamp) disclosing a kind of volute type is for combustible gas generation one vortex flame upwards, vortex flame position one around and be limited in the border (boundary) of swirled air, having an interface (interface) in operating process is not having between the swirled air of gas and the central area being surrounded gas by interface, and gas produces burning therein.This gas lamp has a central shaft (axis) and comprises: a base (base) has the centrally surface that extends laterally of axle; One guard shield (shield) comprises one first, one second axially extended block (section), each block has a upper end and a lower end, be incorporated into base the lower end Fluid Sealing of each block, each block forms a cut-pff wall, cut-pff wall has an arc inner wall (inner wall) and an arc outer wall (outer wall), first, second block is alternately stacked and their edge is contiguous mutually and be separated by the port (air ports) forming tangential direction, therefore form an axially extended chamber, chamber because of port in side in open; First, second block is set up and is arranged in base and surrounds the porch of combustible gas; Gas combines the air entered from port and burns, and the gas of burning forms a flame, and flame and arc inner wall are separated by, and air makes gas flow to port.
But, adopt the guard shield of said structure, outside air enters guard shield inside via relative two ports, such design only can provide fire endurance period to burn, the impact being subject to the flowing of device surrounding air when practical application causes instability, cause being difficult to maintain stable flame height and swirl shape, and only can in flame scale within the specific limits, swirl flame effect could be formed, if when flame scale is less or guard length falls short of, then cannot form obvious swirl flame effect.And the outside cold air sucked only has small part to flow through burner surface, device accumulation high temperature after burning, can be caused.In addition, because bottom of device is blind end, near combustion head, form semiclosed region with around glass.During owing to starting burner, first start to supply gas, and form debita spissitudo igniting ability firing device smoothly at gas.If too preignition cannot be able to light because gas density is too low, and be greater than air due to gas proportion, be easily accumulated in bottom of device.If light a fire too late, may Yin Wasi excessive concentration and produce gas explosion.But or when device will start burning in firm closedown at once, cannot light smoothly due to inner anoxic, also easily cause gas accumulate and produce the danger of gas explosion.Therefore general status will guarantee that security must make the electrically-controlled valve of apparatus continuous ignition function and automatic closed gas, just can avoid the danger of gas explosion, but electrically-controlled valve cost ratio manual ignition device is much higher.
Referring again to No. D621873rd, U.S. Patent number " FIRE TORNADO LAMP ", it discloses a pedestal and a diffuser, the periphery ring of pedestal is provided with the pore of several diffuser inside that communicates, the radial position of pore is arranged askew and the diffuser that communicates, and the lengthwise position of pore is vertical and is positioned at pedestal.When outside air via the pore of arranged askew enter diffuser inner time, air can form one eddy flow, the air that this strand of eddy flow provides flame to need and allow fire endurance period burn and form rotate effect.
But, because air inlet is positioned at plane and the top of port, airintake direction is vertical with flame combustion direction, only can could form swirl flame effect when flame scale is enough large, if just cannot form obvious and stable swirl flame effect when flame scale is less.And the outside cold air sucked only has small part to flow through burner surface, causes glass tube and device accumulation high temperature.And equally because bottom of device is blind end, near combustion head, form semiclosed region with around flow-guiding channel and glass, have as the problem of above-mentioned easy accumulation gas in bottom.Generally to guarantee that security also must make the electrically-controlled valve of apparatus continuous ignition function and automatic closed gas, just can avoid the danger of gas explosion.
Continue referring to " the burner improvement of outdoor flame radiator " Patent Case of No. M461769th, TaiWan, China patent, it is a kind of burner, a Gas Distribution room is possessed in the middle of burner, and being provided with multiple glory hole in end face, Gas Distribution room periphery forms flange surface and can be combined in the upper of pedestal; Above burner, cover cap has a cover body, an air flow method room is defined between cover body and burner, and cover body surrounding is provided with multiple airflow hole, top is then provided with a recessed installation hole, embeds in order to do making glass tube bottom, and be positioned at above the plurality of glory hole and air flow method room, make gas and the abundant mixed combustion of air, form the network of fire of fire row shape, improving combustion efficiency, flame is upwards climbed sharply to a preferred height by stack effect in glass tube, promotes heating effect according to this.
But, the burner of said structure is adopted above Gas Distribution room, to be provided with glass tube for making it produce stack effect, and for enabling air enter glass tube by the below of glass tube, cover body and burner must have air flow method room for air circulation, blow if the easy wind-engaging in outdoor put in use by burner, when burner wind-engaging blows, wind directly directly can blow to the glory hole of Gas Distribution room via air flow method room, easily affect burning condition and flame profile.And spray in pipe by pressurization gas to improve flame height when burning.Due to pressurization gas, to spray into speed fast, is not easy to control igniting opportunity, also can form turbulent-flame, and the outside cold air sucked to only have small part to flow through burner surface, causes glass tube and device accumulation high temperature after burning in glass tube.Equally because bottom of device is semiclosed end, with around air admission hole and glass form semiclosed region near combustion head.As misoperation during igniting, after starting air feed, if the duration of ignition is too late or after starting air feed, the very first time cannot light, easy accumulation high concentration gas is in bottom of device, if user sustained manual air feed constant ignition in unwitting situation likely cause local gas excessive concentration and produce the danger of gas explosion.Generally to guarantee that security also must make the electrically-controlled valve of apparatus continuous ignition function and automatic closed gas, just can avoid the danger of gas explosion.And electrically-controlled valve cost ratio manual ignition device is much higher.
