Description
Technical field
The utility model belongs to cooking appliance design and manufacturing technology field, especially belongs to the monoblock type gas kitchen ranges and manufactures and designs the field, particularly a kind of combined type high heat load burner.
Background technology
Commercial gas-fired stove adopt air suspended type multi-head burner or air blast burner general according to the size of using thermal power, there is the thermal efficiency low (approximately 20% left and right) in it, in combustion product gases, CH, CO, NOx and soot PM pollutant levels are high, and the dry sound of working environment is large, do not meet the energy-saving and emission-reduction Times ' Demand.And the fletcher radial burner with fan-shaped or multiple-head type layout take porous honeycomb ceramic as primary element that grow up recent years, its thermal efficiency is improved significantly, smoke pollution also improves, but ubiquity unit are thermal power is little, product service life is short, the maintenance and repair rate is high and inconvenient, easy tempering practical application security reliability is relatively poor and need provide the necessary shortcomings such as power supply when using.
Recently developed multi-combustor and jointly used whole hybrid chamber technology, but independently burner is unfavorable for further improving efficiency of combustion, whole hybrid chamber combustion gas fed distance and pressure transient cause burning inhomogeneous, require further improvement and improve the thermal efficiency.
Developed at present a kind of full premix integral burner of inner and outer ring, this burner comprises the two-way gas circuit of inner and outer ring, and one the tunnel is responsible for interior ring air feed, and one the tunnel is responsible for the outer shroud air feed.Full premix combustion has very large advantage in energy-saving and environmental protection, aspect efficient, but the combustion characteristics of full premix itself has also determined need to wait for the time of about 1 to 2 minute from beginning to light optimal combustion state, this is an inferior position for the Chinese meal Quick-fry stove, and the unit are thermic load that the Chinese meal Quick-fry stove requires is much bigger than the other types commercial kitchen range.In order to reduce the stand-by period and to increase the unit are thermic load, more common way is to set up air blast and gas ratio valve at present, alleviate the problem of this two aspect by the mode of overheavy firing, but set up blower fan and proportioning valve can increase cost, and produce very large noise.
Summary of the invention
The utility model discloses a kind of combined type high heat load burner according to the deficiencies in the prior art.It is higher that problem to be solved in the utility model is to provide a kind of burner plate structure thermal efficiency, can reduce the stand-by period and improve the unit are thermic load, and the hybrid chamber stable and uniform of supplying gas can further provide the burner of efficiency of combustion.
The utility model is achieved through the following technical solutions:
Combined type high heat load burner, comprise the fuel gas injection pipe, with the combustion gas mixing chamber of playpipe UNICOM be arranged on the burner plate of hybrid chamber, burner plate arranges one in combustion centre, also be provided with the annular firing plate around the central burner plate, it is characterized in that: the central burner plate has independently the first playpipe and the first hybrid chamber; The annular firing plate has independently annular the second hybrid chamber, and annular the second hybrid chamber has and has two group of second playpipe at least, and the annular firing plate is outwards raised gradually by the center and is obliquely installed.
Described central burner plate is plane or globoidal structure.
Described annular firing plate is plane or globoidal structure.
Further in described the second hybrid chamber, second sprays mouth of pipe top the second flow distribution plate that covers the second hybrid chamber area of plane 1/4th to 2/5ths is arranged respectively.
Above-mentioned the second flow distribution plate along continuous straight runs is obliquely installed, and has been evenly arranged pore on the second flow distribution plate.
It is 10 to 40 degree that above-mentioned annular firing plate outwards raises by the center angle that forms with the horizontal plane inclination gradually.
Above-mentioned central burner plate and annular firing plate respectively by metal fixedly trim ring adopt screw or be welded and fixed.
The utility model adopts inside and outside two groups of burner plate structures, adopts the monolithic construction assembly, adopts integral ring-shaped burner plate, can independently regulate the Internal and external cycle combustion efficiency and further improve the thermal efficiency.The utility model arranges two groups of playpipes at least at the annular firing plate, reduce the stand-by period and improve the unit are thermic load by the mode that increases gas circuit at outer shroud, improved burner is used on Related product, according to present test result surface, adopt this structure can be dropped to 1/3 original left and right the stand-by period, simultaneously thermic load is improved nearly one times.
Improving the effective heat duty mode has two kinds, and a kind of is to improve the thermal efficiency and then improve effective heat duty under the condition of same input thermic load; Another kind is to increase the input thermic load by increasing air consumption under the constant prerequisite of the thermal efficiency.Can significantly improve thermic load by the mode that increases air consumption at present, and the burner of main flow all only has one tunnel gas circuit mostly, it is limited only increasing thermic load by this gas circuit, particularly in large-area burner application; Simultaneously, due to when increasing air consumption, the air capacity of its injection is also limited, the air capacity proportioning of gas quantity and its injection unreasonable can the generation tempering, from phenomenons such as flame, Huang Yan, serious also will have influence on combustion conditions, and the thing followed is that the thermal efficiency reduces.
The utility model adopts two-way or organizes the thermic load that increases of gas circuit more, can allow the air capacity of each gas circuit institute injection and the proportioning value that the gas quantity coupling reaches a best, overcome the limited defective of injection air capacity, simultaneously after multipath gas enters combustion chamber, by collision each other, what can also make that combustion gas and air mix more evenly improves the thermal efficiency.Setting up the multichannel inlet duct can improve the thermal efficiency when increasing substantially the input load, the stack of two aspect factors can increase substantially effective heat duty.
Stand-by period is closely-related with effective heat duty, and when effective heat duty was larger, burner plate energy fast lifting reduced and uses the stand-by period to the temperature of infrared radiation.
The integral combustion plate has improved combustibility, but integral ring-shaped burner plate fuel gas flow method of supplying is to improve one of important technical bottleneck of efficiency of combustion, commercial gas-fired stove burner plate technology trends is take the integral combustion plate as the main development direction at present, but large-area its plenum system of integral combustion plate technique is subject to larger restriction, the utility model burns the plate plate and has better heat conduction, thermally-stabilised, and possessing quick heating, shock resistance is strong, the characteristics such as long service life.Annular firing sheetmetal carrier optimal design is ring-type umbrella shape cambered surface form, cambered surface and horizontal plane angle general context 10 to 40 degree, best 10 to 25 degree; Umbrella shape burning cambered surface is evenly pressed close to the heating surface of Heated container, makes that the burner firepower is more concentrated, more violent and minimizing heat energy is excessive, significantly improves the thermal efficiency of burner body.The hybrid chamber fire pot is designed with the flow distribution plate of mist and decompression, adopts woven wire bilayer or multilayer mechanism, and air-flow is more stable, and gas combustion is more even, and the hot merit effect is high.The utility model burner plate adopts up and down double layer of metal trim ring, adopts screw and is welded and fixed mode, makes interior outer burner, fire pot, air inlet pipe become seamless integral body, and sufficient combustion is without tempering hidden danger.
