Description
Technical field:
The present invention relates to cooking apparatus field, particularly a kind of energy-conserving and environment-protective combustor of commercial kitchen equipment.
Background technology:
The fiery section of conventional commercial cooking apparatus burner is single (thousand stove one fire, north and south one fire), valve body, Pipe installing are difficult, loaded down with trivial details, the intensity of a fire, firepower regulate difficulty (being generally fixing firepower formula), these all make cook can not reach arbitrary use according to place, vegetable, hobby etc. to the cooking stove duration and degree of heating, the level of cook is played and is subject to great restriction.The structure of conventional burners makes burning can only adopt rear mixing burning, burning velocity is slow, cause fuel gas buring very insufficient, heat resources serious waste, the thermal efficiency reduces greatly, and often need very large thermic load could meet the duration and degree of heating demand of a simple cooking, combustion noise is large, not energy-conservation, not environmentally.The structure of conventional burners causes gas flow rate slow, incorporation time short (essentially no mixing), under high wind promotes, many combustion gas are just blown to outside burner hearth when going back unburned (imperfect combustion in other words), indoor and outdoors has been discharged to by flue, smoke discharge amount severe overweight, both wasted combustion gas, again severe contamination environment.Conventional burners needs the pipeline flow system of installing huge valve body and complexity thereof, difficulty is installed, operate quite loaded down with trivial details, and there is gap between the parts of one side package assembly, easily cause gas leakage, there is serious potential safety hazard, the burner of package assembly easily causes structures slope and skew on the other hand, causes flame partially to be altered and beats (occurring " Buddha's hand " fire type).The structure of conventional burners also causes inside cavity stream pressure little, and flame easily the internal-combustion of burner (causing tempering), causes potential safety hazard.
Summary of the invention:
The object of the invention is to the deficiency overcoming above-mentioned prior art, there is provided a kind of fiery section various adjustable, intensity of a fire firepower is easy to adjust, fuel gas buring is abundant, the thermal efficiency is high, and gas leakage, flame can be avoided partially to alter beat, the bad phenomenon such as tempering, the energy-conserving and environment-protective combustor of the commercial kitchen equipment eliminated safe hidden trouble.
Object of the present invention is achieved through the following technical solutions:
An energy-conserving and environment-protective combustor for commercial kitchen equipment, comprising: the unsplit frame of disposable casting, and has the electronic ignition device of auger and full-automatic extinguish protection function.
