Description

Universal multiple flame step-less adjustment energy-saving burner

The utility model relates to use on the domestic gas kitchen range a kind of and has the combustion gas regulatory function, and the combustion system that combustion heat intensity is high particularly is used for using the universal multiple flame step-less adjustment energy-saving burner of character various combustion gas far from it.

Existing domestic gas kitchen range, utensil, general all is the burner of atmospheric combustion mode, mainly by nozzle, device, head are formed when drawing, during work, combustion gas is under certain pressure, flow out from nozzle with certain flow velocity, enter air-breathing collapsible tube, combustion gas sucks primary air by the energy of itself, combustion gas mixes with air in induction tunnel, then, flow out, burn through the head fire hole.The weak point that this burner exists is: (1) burner all is to design by certain combustion gas composition, also change when the combustion gas composition changes and is directed at its calorific value, severe and combustion characteristics, combustion conditions such as carbon monoxide content will change in the thermic load of burner, primary air ratio, combustion stability, flame structure, the flue gas.City with multiple system gas resource usually runs into following two kinds of situations: a kind of is the development of combustion gas scale or the change of system source of the gas, and originally the combustion gas of the Shi Yonging another kind of combustion gas that do as one likes matter is different for a long time replaces.Another kind of situation is basic source of the gas generation emergency episode or peak hours, and basic source of the gas deficiency need be mixed the character combustion gas different with original combustion gas in supply system.No matter which kind of situation takes place, and all can obtain burning to the user and change, when the combustion gas composition changes when big, the change of combustion conditions, burner just can not normal combustion, will cause huge numbers of families from new adjustment or replacing burner like this.(2) during burner combustion a premix part air, rather than the required air that all burns, so thermal intensity of fire port, ignition temperature is restricted, can not satisfy the requirement of some technology, when thermic load requires need increase fire hole when big, enlarged head size, structure are heavy greatly again, and consume combustion gas.(3) burner head generally all is to adopt iron casting to form, and the fire lid is that cast iron, cast copper or stamping parts are made, combustion heat loss is big, fire hole and fire lid oxidation or distortion after use a period of time, and combustion conditions changes, the imperfect combustion situation occurs, not only waste combustion gas but also contaminated environment.People watch attentively to some extent to new energy-saving gas oven for this reason, China's utility application number is ZL982043589, and a kind of energy-saving burner is provided, and is made of shower nozzle, Gas Pipe, one end of Gas Pipe is communicated with the gas burning system of kitchen range, and the shower nozzle of the other end (nozzle) is supported by Gas Pipe.By the reaction barrier air of tableware bottom, the fire point burns during work.This burner is than the normal atmospheric burner, has firepower and concentrates, and certain energy-saving effect is arranged, but combustion product gases concentration height, noise is big, safety in utilization is poor, is not widely used as yet.

To sum up state the weak point that burners in prior exists, usually there is the imperfect combustion situation in actual applications, comparatively serious when particularly public cooker uses big fire, contaminated environment not only, harm to human body, and waste a large amount of combustion gas resources, and give the user, bring economic loss to society, study the burner generalization for this reason, improve burning structure, improve the thermal efficiency, saving the energy is the important topic that the present whole society pays close attention to.

The utility model is that a kind of combustion gas step-less adjustment function that has will be provided, multiple flame structure, the general purpose type energy-saving burner that combustion heat intensity is high, this burner can change the combustion protium and the combustion case combination, uses in various combustion gas, can be by the requirement of technology, reach the different thermic loads and the flame structure of different calorific intensitys, during high load capacity, the violent heating of firepower is fast, underload insulation uniform temperature height, thus reach burner generalization, multi-use, energy-efficient purpose.

The purpose of this utility model is to realize like this, on present gas kitchen ranges, gas burning system connects or changes a universal multiple flame step-less adjustment energy-saving burner, this burner is mainly by the nozzle housing, needle valve, air chamber, mixing tube, thermosistor, flame fixed cover is formed, be connected with needle valve in the nozzle housing, can on the internal thread of housing, rotate, the upper end of valve body is processed with angle of throat, the hypomere external screw thread is connected with the housing bottom internal thread or regulates, there is the combustion gas through hole at the hypomere middle part of housing, the internal thread in hole is connected with gas joint, center, housing stage casing is processed with gas jet orifice, advancing of spray orifice, export processing has angle of throat, outlet angle of throat enlarging relatively, the outer wall of housing has airport, the external screw thread of housing epimere induction tunnel is connected with air chamber bottom internal thread or regulates, mixing tube epimere endoporus is processed with two sections disturbance steps, external screw thread is connected with the connector adjusting nut of thermosistor or regulates, thermosistor is by adjusting nut, the following cover that connects, middle supporting plate, the assembling of last connection cover connects into, going up of thermosistor connects the middle flame fixed cover that is equipped with of cover, flame fixed cover has the fire hole flame fixed cover, short-flame grid flame fixed cover, the grid flame fixed cover can be selected to change by technological requirement.
