Abstract

The utility model provides a gas burner which can burn four gases and is composed of eight components. The utility model is characterized in that the gas burner is provided with a replaceable injecting nozzle, a cavity distributing chamber is arranged between a top and a bottom head covers, bar-shaped holes mutually form 90 DEG angle, the gases mix again and can burn when ignited, and the flame distribution is uniform under the condition of heating of an annular flame holder. The gas burner of the utility model has the advantages of simple structure, easy manufacture, and simple operation and maintenance. The head cover is made of heat-resisting cast iron. The combustion is complete, one gas burner has multiple uses, the energy and the investment can be saved, and the gas burner can burn other fuel gases after the injecting nozzle is replaced but not the head cover. The utility model can be extensively used for oilfields, enterprises or institutions with the gas source, hotels, canteens, and tea stoves.

Description

Gas burner

The new-type gas burner of the utility model is a kind of novel four kinds of gas burners of skull combustion that do not change, and is applicable to the unit dining rooms such as enterprises and institutions, restaurant of source of the gas, the usefulness of drinking water boiler.

Traditional atmospheric gas burner has following some deficiency: the one, be designed to fire a kind of burner of pure gas, and interchangeability is poor; The 2nd, gas nozzle is many, changes trouble, the waste raw material; The 3rd, nozzle causes more transfers the wind plate washer many, bad control, incomplete combustion; The 4th, body of heater sand rotating process specification requirement height is difficult for ensuring the quality of products; The 5th, the special combustion gas of can not burning is (as the poor natural gas of the carbonated 70% of Shengli Oil real estate; The 6th, the thermal efficiency is not high.

For overcoming the deficiency of traditional atmospheric gas burner, the new-type gas burner of the utility model provides a kind of energy-saving burner that skull can fire four kinds of combustion gas (liquefied gas, town gas, natural gas, carbonated 70% poor natural gas) that do not change, it has the following advantages: the one, and flammable multiple combustion gas, interchangeability is good; The 2nd, change nozzle, transfer wind easy, materials are economized, cost is low; The 3rd, the body of heater sand rotating process is simple, easily processing; The 4th, designed combustion device skull is a Double layer lid, has increased combustion gas cavity distributor chamber, and it is more abundant that combustion gas is mixed with air; The 5th, the higher authorities portion of covering has increased annular flame holder, and wind resistance power is strong, has solved the poor natural gas burning problem of combustion carbonated 70%; The 6th, thermal efficiency height; The 7th, skull is processed with heat-resisting cast iron, the intensity height; The 8th, be designed to the bar shaped fire hole, skull bar hole and gas-flow be to mutually at an angle of 90 up and down, mixes more fully, and burning is fully, and is safe and reliable.

The new-type gas burner of the utility model, it is made up of rubber hose coupling (1), stage clip (2), accent wind plate washer (3), small nozzle (4), injector (5), head (6), time skull (7), last skull (8) etc.Feature of the present utility model is that rubber hose coupling (1) port of export is designed to double-deck screw thread, small nozzle (4) links to each other with rubber hose coupling (1), head (6) is inlayed and is linked to each other with following skull (7), last skull (8), (7), (8) are provided with a cavity up and down between the skull, last skull (8) is provided with an annular flame holder, (7), (8) go up down skull and adopt heat-resisting cast iron manufacturing, the lower end that (7), (8) are gone up skull down is provided with bar hole, its assembly is 90 ° of angles each other.

The new-type gas burner of the utility model, it is made up of rubber hose coupling (1), stage clip (2), accent wind plate washer (3), small nozzle (4), injector (5), head (6), time skull (7), last skull (8) etc.Characteristics of the present utility model are that rubber hose coupling (1) port of export is designed to double-deck screw thread, the minor diameter screw thread links to each other with replaceable small nozzle (4) box, major diameter screw thread and injector (5) entrance point box is connected as one, step 8 millimeters deep in head (6) Che Youyi, last skull (8) top specialized designs has an annular flame holder, 31 wide 1.5 millimeters bar shaped fire holes of back-plane design, the bottom car has an outer step high 7 millimeters, following skull (7) top car has in one step inlay with last skull (8) for dark 8 millimeters, forming a cavity is the combustion gas distributor chamber, 11 wide 2 millimeters bar holes of back-plane design, the bottom car has an outer step to inlay in aggregates with head (6) for high 7 millimeters, skull (8) (7) all adopts heat-resisting cast iron to make up and down, and skull bar hole and gas-flow are to 90 ° of angles each other up and down.

Below with reference to accompanying drawing the new-type gas burner of utility model is further described.

Fig. 1 is the longitudinal sectional drawing of the new-type gas burner concrete structure of the utility model.

Fig. 2 is the longitudinal profile accompanying drawing of the new-type gas burner small nozzle of the utility model part concrete structure.

Form by 8 parts with reference to the new-type gas burner of figure one the utility model, rubber hose coupling (1) entrance point is connected with the source of the gas sebific duct, the port of export is designed to double-deck screw thread, the minor diameter screw thread is connected with replaceable small nozzle (4) box, major diameter screw thread and injector (5) box is connected as one, the centre accompanies stage clip (2), transfer wind plate washer (3), head (6) is cast as one with injector, head end car has in one step have an outer step to inlay for high 7 millimeters with following skull (7) bottom car for dark 8 millimeters, thick 7 millimeters to be milled with 11 wide 2 millimeters bar-shaped troughs be dispensing orifice to base plate, the top car has in one step with last skull (8) bottom car the high 7 millimeters embeddings mutually of one outer step be arranged for dark 8 millimeters, middle formation one cavity is the combustion gas distributor chamber, base plate is milled with 31 for thick 7 millimeters, wide 1.5 millimeters bar shaped fire hole, the top specialized designs has an annular ring flame holder, gas-flow to skull (8) up and down, (7) bar hole 90 ° of angles each other, combustion gas is fully mixed once more with air, the grate flame distribution is equal, and burning fully.

The new-type gas burner of the utility model is with following mode of operation: in the time will lighting a fire, open air intake valve earlier, connect rubber hose coupling (1) by sebific duct, enter replaceable small nozzle (4).Different combustion gas character are changed the different spray nozzles diameter, combustion gas is under certain pressure, flow out from nozzle with certain flow velocity, combustion gas enters injector (5) by the energy of itself by transferring wind plate washer (3) to suck primary air, combustion gas and air mixed once enter head (6), enter and last skull (8) middle cavity distributor chamber by following skull (7) bar hole, by because of gas-flow to the 90 ° of angles each other of skull bar hole up and down, mix fully once more, when the higher authorities' cover strip fire hole was lighted a fire, bar shaped fire hole face caught fire and lights, under the heating once more of annular flame holder, burn, by transferring wind plate washer (3) to regulate air capacity, just appear at the blue band flame of bar shaped that a rule is stable on the grate face, distribute all, burning fully, pollute little, thermal efficiency height, the making full use of of carbonated 70% poor natural gas that has particularly solved burning Shengli Oil real estate, general burner does not have flame holder to misfire, close air intake valve when inactive, fire promptly goes out, and finishes once-through operation.
