Description

Gas combustion device and gas fireplace

Technical field

The present invention is and gas combustion device-dependent；Particularly relate to a kind of gas combustion device of high-effect decorative flame And gas fireplace.

Background technique

Existing straight-line (DIRECT-VENTED) gas fireplace uses natural equilibrium intake and exhaust mode, exhaust outlet and air inlet Mouth connects combustion chamber with horizontal or vertical direction, and is connected to outdoor, and air and combustion chamber are completely isolated therefore in line within doors (DIRECT-VENTED) gas fireplace is current safest fireplace.Since exhaust outlet and air inlet are all connected to outdoor, to apply Work with it is easy for installation, exhaust pipe and air inlet pipe generally use the design of tube-in-tube, and vent line has outer tube air inlet pipe encirclement One smaller radial concentric inner hose row is used as exhaust pipe, and outer tube is connected to the inlet channel on rear side of furnace body simultaneously；Inlet channel can be connected to Outside imports fresh air in combustion chamber via single or multiple air inlet.After the inner tube of connection combustion chamber will be will burn Furnace body (FIREBOX) is discharged outside in high-temp waste gas.Burner is set to the intracorporal combustion chamber of furnace, generates when due to burner combustion high Temperature makes in combustion chamber that when gases are heated, they expand and generates buoyancy upward, flows through exhaust pipe discharge by stack effect (STACK EFFECT) Combustion chamber, while negative pressure is formed in closed combustion chamber, external fresh air is sucked into combustion chamber, to provide continuous burning Required oxygen.Wherein, in order to allow gas fireplace that good flame visual effect is presented and provide radiant heat, in the front side of furnace body It is provided with transparent glass shielding, allows user that can shield the ornamental light with combustion flame that is experiencing furnace interior by glass With heat.In addition to front glass side, furnace body is spaced apart, and fireplace shell is arranged to completely cut off furnace body and generates high temperature to building, Enable shell close to exterior walls of buildings, space needed for reducing installation.Section can be with Interior Space between high-temperature furnace body and fireplace shell Control valve and control module are then installed in the space of gas progress heat exchange, furnace body bottom side and fireplace shell, also will be installed fan sometimes Reinforce convection current to accelerate the heat exchange between furnace body and room air, to improve the thermal efficiency and room temperature is accelerated to be promoted.Above-mentioned Fireplace structure, which can join, makes United States Patent (USP) 4793332 " DIRECTED-VENTED GAS FIREPLACE ".

However, good in line gas fireplace has to comply with multinomial design requirement and specification.It is more related main to burning Demand and specification include: (1) high efficiency: since intake and exhaust are all set to outdoor, hot service efficiency must be improved to meet correlation Regulation, if the delivery temperature of straight gas-removing fireplace and flow it is excessively high can all make fireplace efficiency reduction.(2) close to completely burned: Hundred completely burneds of percentage can not be reached in reality, but the carbon monoxide harmful substance produced by the completely burned with it is black The discharge amount of cigarette can be lower.General completely burned degree not instead of not completely to generate the absolute value of carbon monoxide as measurement, Relative to burning scale as measurement, amount of carbon dioxide can represent burning scale.So burning cleanliness is usually with CO/CO₂'s Relative ratio is as measurement.If usual CO/CO₂Ratio is relatively complete less than 0.004 representative burning, and the fewer generation of this ratio is more Few black smoke amount.(3) large scale crocus flame flame kenel and color: is presented since fireplace must visually imitate combustion of wood To accord with and decorate the aesthetic demands of flame, the colourless or blue visual demand that can not meet decorative flame is presented in flame.(4) must It must adapt to various combustion gas: since people's livelihood fireplace must be applied to many areas, generally have to be suitable for natural gas with a fireplace (NG) and barreled gas (LP)；Horizontal and rectilinear in line equal actual uses situation.And the combustion gas of each department is variant, therefore Fireplace design must be reached outside the demand, moreover it is possible to adapt to the combustion gas of various composition.(5) burning scale on a large scale is adapted to: for Increase application range, same fireplace design must adapt to large-scale burning scale, and meet the demand.

However the demand often contradicts each other, for example, the raising thermal efficiency makes delivery temperature and flow-reduction also simultaneously It is be easy to cause deficiency of air, cause incomplete combustion and generates excessive carbon monoxide and black smoke.It is anti-, excessively completely burned When, and it is be easy to cause colourless or blue flame, the crocus for meeting decorative flame visual demand can not be presented.And it is single with a Fireplace will adapt to each department difference natural gas (NG) and barreled gas (LP) its fuel performance simultaneously just very big difference.Such as Natural gas needs less oxygen-supplying amount than barreled gas, reaches the good situation of combustion of natural gas in same fireplace, if using bucket Dress gas is but possible to will cause incomplete combustion.

In order to solve these above-mentioned needs of problems simultaneously, there is comparable degree of difficulty, usual non-single means can be reached, This is because in fireplace combustion chamber, when burning, generated burning waste gas can generate high thermal current and towards furnace in furnace body Exhaust outlet flowing at the top of body.Since exhaust outlet sectional area is much smaller than the sectional area of top of combustion chamber, it is small to be only capable of offer one Partial high temperature gas flow passes through, and the heated gas largely risen will receive the wall surface at the top of furnace body and stop and be formed down It flows back (circulation), and is stranded in furnace body and accumulates heat, then heat is stayed in by room by the heat exchange outside furnace body It is interior.The service efficiency of the energy can be determined in the number of the heat of furnace body accumulation.If too discharge furnace body can make efficiency to high-temperature gas fastly It is lower, if anti-too slow discharge can hinder the importing of outside air, is unfavorable for completely burned.

In addition, when outside air from air inlet import furnace interior when, if burner air supply opening farther out from flame when, be easy Flowing with high temperature gas flow caused by burning waste gas interferes with each other, and forms flow-disturbing, and mutually mix with burning waste gas.It not only can shadow The smooth discharge for ringing burning waste gas, can also reduce the oxygen concentration of combustion flame surrounding air, can not effectively control supply burning Oxygen-supplying amount needed for device completely burned.Especially when the scale of burning increases, since high temperature can reinforce indoor convection current of burning, make Air inlet mixed combustion offgases degree aggravation, it is easier to cause imperfect combustion.

Prior art such as United States Patent (USP) 4793332 " DIRECTED-VENTED GAS FIREPLACE " discloses a height The through type gas fireplace of efficiency designs, and reaches low CO (CO) and nitride by optimization combustion gas and air mixing ratio (NO_x) discharge amount, while delivery temperature and speed can be reduced to improve the thermal efficiency.

United States Patent (USP) 5016609 " DIRECT VENTED MULTI GLASS SIDE FIREPLACE " discloses a increase The efficient through type gas fireplace of two sides glass designs, and discharges into throughput using diversion mode reinforcing, but furnace at the same time The heat exchange structure of enlarged surface product is added at the top of body with the increased thermal efficiency.

" UNIVERSAL HORIZONTAL-VERTICAL (H-V) the DIRECT-VENTED GAS of United States Patent (USP) 5452708 HEATING UNIT " discloses a high efficiency through type gas fireplace design for being common to horizontal and vertical ventilation.It is mixed to control Gas ratio, setting channel and deflector make multiple air inlet concentrate simultaneously close and are located at combustion tube lower position, to improve combustion front For oxygen concentration, baffle is set before exhaust outlet above furnace body, to control the path of high-temp waste gas discharge.

" the DIRECT VENT GAS APPLIANCE WITH VERTICAL AND of United States Patent (USP) 5947113 HORIZONTAL VENTING " discloses the high efficiency through type gas fireplace design of a horizontal and vertical ventilation of energy, and setting is logical Road is not connected directly with high-temperature furnace body, and baffle is arranged before exhaust outlet above furnace body, to control high-temp waste gas flowing path.

" DIRECT VENT FIREPLACE WITH BAFFLE, the DIRECTIONAL EXHAUST of United States Patent (USP) 6432926 AND VENT AIR COLUMN " discloses a through type gas fireplace design, increases shelves flowing plate before exhaust outlet in furnace body and improves Heating surface area, and air flue is set and is directed the air into below furnace body, thermal effect can be improved in the obstruction due to reducing the heat exchange of furnace body surface Rate.

Although various forms of partitions and deflector is added in these in the combustion chamber or inlet channel design is different, have several On the one hand item common point is the exhaust pathway for controlling high-temp waste gas, the flow path of high-temp waste gas is made to lengthen or increase combustion chamber Heat exchange area at the high temperature of top is to increase heat exchanger effectiveness, but reduction flow velocity that can be average, makes high-temp waste gas will not be Excessive turbulence and reflux are generated in combustion chamber and the degree of air inlet mixed combustion offgases is caused to be aggravated.It on the other hand is then that will burn The setting of the air inlet of room furthers and is distributed in the position of the rough lower section of burner to improve burner flame vicinity flow field Oxygen content, promote completely burned.Wherein or the area that inlet channel directly contacts high-temperature furnace body is reduced, drops intake air temperature It is low, increase intake efficiency.

Although the prior art and design setting can all reach certain benefit, for flame kenel, relatively lack integration Burner carries out more precise control to supersonic combustor and air inlet, therefore in the relevant demand of correspondence and specification, is applicable in Range is more restricted.

However, existing elongated 1 structure of gas combustion device of discussion is as shown in Figures 1 and 2, it is for elongated tube body 10, tube body 10 is straight line or bending, and tube body 10 offers multiple ventholes 102 along its length axial direction, by one end confession watt of tube body 10 This injection, by carrying out once mixed gas.The gas through primary mixed gas is injected to be exported by venthole 102.Existing gas combustion When burning gas, the flame generated from the venthole 102 does effectively auxiliary air needed for burning due to lacking device 1 Control, therefore, the height of flame can not be improved effectively.If the visibility of flame to be improved and height and, increase the confession of gas Should measure also equal proportion or can not effectively increase the scale of flame visibility.

This is because after venthole 102 increases gas supply amount in order to improve flame height, the increase of flow velocity and heat The generation of 102 surrounding flow field sinuous flow of venthole will be increased.Sinuous flow is a kind of flow regime of fluid.When flow velocity is smaller, stream Body laminar flow, molecular motion direction is identical as flow direction, and streamline does not mix mutually, referred to as laminar flow；When flow velocity increases to centainly When degree, molecule can be generated perpendicular to the movement with flow direction, cause the irregular small whirlpool in many of flow field, referred to as disorderly Stream.Sinuous flow can be strengthened in heat transmitting or be sufficiently mixed.

Due to laminar flow be conducive to generate the higher crocus of visibility diffusion flame, and sinuous flow can reinforce burning when it is flammable The mixing of gas and surrounding air.But burning must have certain condition and reaction speed, be excessively mixed into combustion air and be easy Colourless or blue flame is caused, nitride (NO is generated_x) or local velocity it is excessively high and be unfavorable for the situation of completely burned.These shapes Condition can all make flame visibility reduce and beat in a discontinuous manner, therefore flame visibility will not be because of the supply of increasing gas And equal proportion or the effectively visibility and visual scale of the diffusion flame of increase crocus.

When applied to gas fireplace, sinuous flow is generated in closed furnace body can reinforce the disturbance and convection current of internal gas flow, special It is not to be easy to be interfered by sinuous flow by the extraneous high air of oxygen concentration that imports, therefore be difficult control to have when increasing flame scale The burning condition of benefit.Therefore perfect, still to have much room for improvement place is not attained in the design of existing gas combustion device 1 yet.

It please join shown in Fig. 3 to Fig. 6, be a preferred embodiment of the present invention gas combustion device 2, include a burner 20 With a guiding device 26.

The burner 20 is including a shell 22 and a tube body 24 in elongated, the shell 22 tool be by two it is elongated partly Shell involutes, which has individually a vertical plate 222, which is separated by a spacing, in two vertical plate 222 Apical margin between form a gas export 224 upward, the gas export 224 be along the shell 22 length it is axially extending.The pipe Body 24 is located in the shell 22, and coats jointly for two half-shell.One end of the tube body 24 is for gas injection, and the tube body 24 With multiple ventholes 242, the venthole 242 is the long axial setting along the tube body 24, and the venthole 242 is corresponding is somebody's turn to do Gas export 224.The gas for injecting the tube body 24 is up scurried out by the venthole 242 from the gas export 224.

The guiding device 26 includes partition 28, a fixed frame 30, multiple first shim 36, Duo Ge being laterally arranged Two compartment piece 38 and two baffles 40.The partition 28 has a upper surface 282, a lower surface 284 and runs through the upper and lower surfaces 282, 284 opening 286, the opening 286 are axial long axial parallel with the burner 20 in elongated and its length.The fixed frame 30 is set Be placed in the lower surface 284 of the partition 28, including a fixed plate 32 and a pedestal 34, which has one through thereon, under Opening 322, the peripheral part of the opposite sides of the opening 322 has individually multiple fixing grooves 324, and the fixing groove of every side 324 be to be alternatively arranged along one with reference to axial direction D, wherein reference axial direction D is parallel to the long axial of the burner 20.The bottom Seat 34 is located at 32 lower section of fixed plate and has a long hole 342, which extended along reference axial direction D.The burner 20 Vertical plate 222 be to be penetrated in the pedestal 34 from the long hole 342 by 34 lower section of the pedestal and combined with the pedestal 34.

First, second shim 36,36 is located in the pedestal 34.One lateral margin of first shim 36 is slotting Enter the opening 322 wherein among the fixing groove 324 of side, makes first shim 36 along reference axial direction D in interval It is arranged and is located at the side of the gas export 224 of the burner 20.One lateral margin of second shim 38 is to be inserted into the opening It is located at the gas export 224 among the fixing groove 324 of 322 other sides relative to the another of first shim 36 Side.Respectively first shim 36 has one first grooving 362；Respectively second shim 38 has one second grooving 382.

Two baffle 40 is made by transparent material, and the present embodiment is strengthened glass.Two baffle 40 be in elongated and Its length is axial long axial parallel with the burner 20, which passes through the opening 286 of the partition 28, and the baffle 40 is directly On the spot be inserted in first grooving 362, another baffle 40 is erectly inserted in second grooving 382, make this two Baffle 40 is facing and the gas export 224 is located between two baffle 40.Respectively the baffle 40 has an apical margin 402, respectively the top The position of edge 402 is higher than the upper surface of the partition 28.As a result, in 28 lower section of the partition two neighboring first shim 36 it Between formed one first air intake 364；One second air intake 384 is formed between two neighboring second shim 38.Described first Air intake 364 and second air intake 384 are the spaces being respectively communicated between two baffle 40, and first air intake 364 and second air intake 384 be respectively facing the side of pedestal 34, and enter the air-flow of first air intake 364 by side To air inlet.In practice, 286 peripheral region of opening that two baffles are connected to the partition 28 can be also designed.

In addition, the two sides of the gas export 224 are more provided with two folded plates 42, which set along reference axial direction D It sets and is located between the gas export 224 and two baffle 40, respectively the folded plate 42 is with respectively the distance between baffle 40 It gradually decreases from lower to upper.Respectively the folded plate 42 have multiple perforations 422, the perforation 422 be along reference axial direction D setting, and The position of the perforation 422 is lower than the position of the gas export 224.

It please cooperate Fig. 6, gas carries out once mixed gas with air in the tube body 24 of the burner 20, then goes out in the gas 224 output of mouth starts to burn.During burning, in the hemi-closure space that is formed between two baffle 40, flame makes air The stack effect for being heated and rising, and formed forms negative pressure in two baffles, 40 upper edge.By this negative pressure, continue air It is attached that ground by first air intake 364 and second air intake 384 of 28 lower section of the partition is introduced to the gas export 224 Closely, a part of air is introduced between two folded plate 42 by the perforation 422 and is mixed with gas, for combustion-supporting.The perforation 422 position is lower than the position of the gas export 224, can avoid the gas export 224 through the air of the perforation 422 Gas pushes and influences the height of flame.

The air of another part is mixed in the position for being higher than two folded plates 42 with gas, and is oriented to the respectively gear upwards with low-angle Plate 40.Air-flow through being oriented to indirect blows to flame since Coanda effect makes air-flow be adsorbed on respectively 40 surface of baffle.Guiding Cooperation Coanda effect can make secondary air streams be attached to baffle 40 to continue longer stream away from and then capable of maintaining more stable after air-flow is heated The flow field of ascendant trend.The range for substantially extending flame laminar flow, slows down the generation of sinuous flow.

So-called Coanda effect is to make to generate skin-friction force between the body surface flowed through due to the viscosity of fluid, makes to flow The air-flow velocity crossed near body surface slows down, as long as the Curvature varying for the body surface that air-flow is flowed through is not too big, flow velocity Slow down will lead to and import air and can be attracted on body surface and flow.Once but flow velocity is along the pressure for flowing through body surface When gradient becomes zero or is negative, fluid is no longer attracted to just generate when flowing on body surface and separates and supervene vortex.

The flame of script obtains stable and uniform extension by the guiding of air curtain as a result,.In identical burning scale Under, the visibility of flame visually can be greatly improved when observation in front.Flame can be observed from side by air curtain pressure It shortens into flat.Simultaneously because 40 height of baffle be not necessary to it is too high i.e. effective.

Since first, second air intake 364,384 is located at below the partition, therefore, will not influence on the partition 28 The flowing of the air-flow of side flows up the air-flow of 28 top of partition steadily.User passes through transparent baffle 40 It may be clearly seen that flame.Again because the lower fresh air of partition 28 can be mixed without high-temp waste gas is directly directed to two two baffles 40 Between combustion range in, the high air of oxygen concentration can be concentrated and effectively be directed to combustion range, burning can be greatly improved and imitated Rate.

Further, since first shim 36 and second shim 38 of gas combustion device 2 formed it is multiple The setting of turning channel, can effectively reduce the air inlet disturbance of combustion zone, and control intake uniformity, effectively prevent being tempered, together The heat-sinking capability of Shi Tigao gas combustion device 2 reduces by 2 temperature of gas combustion device, to improve safety.

Gas combustion device 2 of the invention is not in the case where increasing gas supply amount, compared to existing gas combustion Device 1, can increase the height of flame, also achieve the effect that save gas.Further, since air-flow be present laminar flow state up Therefore flowing can allow the shape of flame to maintain to stablize, more can up guide the hot gas that flame generates, reduction accumulates on The heat of gas combustion device 2 all around.In practice, if when of less demanding for flame height, can also be not provided with this two Folded plate 42, equally can achieve makes flame height be higher than flame height caused by existing gas combustion device 1.
