Abstract

The utility model provides a multi-fire hole energy-saving gas burner, which consists of a furnace body, an insulated cylinder, a gas inlet pipe and a separator board, wherein, the furnace body consists of porous roof plates, a bottom plate and a furnace wall. The utility model is characterized in that the hollow insulated cylinder is arranged at the center of the furnace body; an external pre-heating chamber is formed between the furnace wall and the insulated cylinder; the space in the insulated cylinder is an internal pre-heating chamber; a plurality of flaming pipes are arranged between the roof plates and the bottom plate in the internal and the external pre-heating chambers; a plurality of gas elbows are arranged on the bottom plate of the internal pre-heating chamber, while nozzles provided with an ignition switch are arranged at the other ends of the gas elbows; the nozzles are inserted into the bottom part of the flaming pipes; gas runs into the external pre-heating chamber through the gas inlet pipe and then into the internal pre-heating chamber and is burnt in the flaming pipes via the gas elbows and the nozzles. As preheated fully by the pre-heater, the gas is expanded and the volume is increased, which is conducive to the full combustion of the gas, thus achieving the purposes of energy saving and environmental protection.

Description

A kind of many fire holes energy-saving gas burner

[technical field]

The utility model relates to a kind of gas burner, is a kind of cooking stoves such as office, school, enterprise, hotel, dining room that are used for specifically, a kind of many fire holes energy-saving gas burner that the copper stove uses.

[background technology]

At present each office, school, enterprise or restaurant adopt clean, sanitary gas burner to cook mostly, but common not with the burner of blower fan, and firepower is too little and burn insufficiently, can not satisfy the demand of high firepower, can not satisfy cook, the needs of cooking.The burner big energy-consuming of tape drum blower fan burner and restricted by electricity consumption.Users wish to have a kind of firepower big, do not need air blast, the better gas burner of energy-saving effect.

[summary of the invention]

For overcoming the above-mentioned defective of existing burner, the utility model provides a kind of many fire holes energy-saving gas burner, to strengthen firepower, makes full use of heat energy, improves energy-saving effect, not restricted by electricity consumption, reduces use cost.

For solving its technical problem, the technical solution adopted in the utility model is: design a top board and a base plate that comprises porous, body of heater, isolating cylinder, air inlet pipe, division board, the gas transmission bend pipe and the igniter of band air nozzle, be characterized in: 1. body of heater is made up of the top of porous and base plate and furnace body wall, center fixation at body of heater has hollow isolating cylinder, form outer preheating chamber between furnace body wall and the isolating cylinder, in the isolating cylinder is interior preheating chamber, isolate barrel and be provided with the breach of a ventilation, between side of this breach and furnace body wall, be provided with a division board from the base plate to the top board; Be provided with a plurality of through holes on the base plate in isolating cylinder, each through hole is connected with a gas transmission bend pipe, the other end of gas transmission bend pipe is equipped with the silk mouthful air nozzle that connects, each air nozzle all inserts a spit tube inside, spit tube is sealedly connected on the interior top board of body of heater and each corresponding through hole of base plate and stretch out outside the base plate spit tube lower end, forms air intlet; 2. described spit tube is the little down big tubaeform blank pipe of, and quantity is 2～5, is sealedly connected on the top board and the through hole between the base plate in the body of heater; 3..Through-hole aperture on the described body of heater top board is big, and the through-hole aperture on the base plate is little, and top board is identical with via count on the base plate, and is located at outer preheating chamber or and interior preheating chamber.

The utility model has been compared following beneficial effect with existing burner: 1. because in combustion process, the body of heater top board is subjected to passing to preheater under the high temperature, newly advance combustion gas through the preheater preheating, temperature is risen, volume increases, enter interior preheating cavity in the isolating cylinder from the indentation, there of column type isolating cylinder, deliver in the spit tube by the nozzle of gas transmission bend pipe again, drive air upwards and air mixing after-combustion.Increased the area and the time of gas-preheating, made full use of waste heat, improved the temperature of combustion gas, helped improving the firepower of burner, be fit to needs big fire cooking stove and use, used as restaurant, dining room, enterprise.2. utilize the heat of self to heat owing to the novel combustion gas of this reality, so fuel gas buring is abundant, and the pernicious gas that gives off is obviously reduced, and helps reducing the pollution to environment.3. the through hole that connects on bottom hole and the top board of spit tube forms air, fuel gas buring passage, in spit tube is located at preheating chamber or and outer preheating chamber in, it is protruding that the preheater base plate is passed in the spit tube lower end, mobile with better acceleration air.
