Abstract

An efficient energy-saving inflamer consists of a furnace header (2) and a stack (4). The efficient energy-saving inflamer is characterized in that the furnace header (2) is a hollow ring form which has a cylinder-shaped filter element (1) in the central section. The furnace header coated with a refractory layer in the upper part is set in the cavity. The refractory material layers on the top of the furnace header are equipped in the lower body wall of the furnace header. A flaming tube is introduced to the furnace header soleplate centre, and the holes are equipped in the upper body wall of the flaming tube which is set in the cavity. An inlet pipe (7) extending out of the furnace header soleplate is positioned in the lower flaming tube. An inlet pipe (10) is set on one side of the furnace header, and an outlet pipe (9) is set on the furnace header soleplate. The furnace header outlet pipe (10) connects with the inlet pipe (7) of the flaming tube through pipeline (8).

Description

A kind of efficiency energy saving burner

[technical field] the utility model relates to a kind of gas burner, is a kind of gas burner that is used for the cauldron cooking stove in office, school or enterprise, restaurant specifically.

[background technology] is present, each office, school, enterprise or restaurant, the more clean, sanitary gas burner of most employing is cooked, cooking, but this burner in the past, can only can not use low-pressure gas source with high pressure or middle pressurized air source, otherwise just can not burn, or firepower is too little, can not satisfy that large stove is cooked, the needs of cooking.And the price of low-pressure gas source such as natural gas, liquid alcohol is lower than the high-pressure air source, and the source is wide, helps reducing the cost of cooking of cooking, energy savings.Therefore, how with the gaseous state or the liquid fuel of low pressure, by suitable burner, it is strong to make it to produce firepower, and thermal efficiency height is fit to the requirement of cauldron cooking stove, is still the problem that users are concerned about and wish to solve.

[summary of the invention] only is fit to use high, middle pressurized air source for overcoming existing burner, can not use the defective of low-pressure gas source or liquid fuel, and the utility model provides a kind of can use the gaseous state of low pressure and the efficiency energy saving burner of liquid fuel.

For solving its technical problem, the technical solution adopted in the utility model is: the annular burner of a hollow of design, be provided with cylindrical combustion chamber at the middle part of burner, combustion chamber stretches out the burner bottom, scribble refractory masses on the top body wall of combustion chamber, have a plurality of passages on the body wall of the bottom of combustion chamber, bottom at combustion chamber is provided with spit tube, the top tube wall of this spit tube is provided with a plurality of apertures and stretches in the combustion chamber chamber, furnace core board is stretched out in the bottom of spit tube, and is provided with air inlet pipe on the tube wall that stretches out the combustion chamber base plate; On the body wall of burner one side, be provided with air inlet pipe, be provided with the ozzle of giving vent to anger in burner bottom, between the air inlet pipe of the escape pipe of burner and spit tube, connect as one by metallic conduit; Bottom at burner is connected with columnar shaft by screw, and the shaft bottom is provided with air inlet, and air inlet is provided with electric fan or air blast.During work, gas or liquid fuel enter burner from the air inlet jet pipe of burner, preheating gasification in the burner cavity, be input in the spit tube of combustion chamber bottom through the escape pipe of pipeline then from burner, a plurality of through holes ejections from the spit tube sidewall at last, as long as on the gas outlet of spit tube, install electronic lighter, just the gas or the liquid of ejection can be lighted, flame is emerged from the burner mouth, in order to cook, cooking, heat up water, the shaft bottom air inlet of burner bottom is provided with electric fan, or the lower end connects air blast by pipeline, and air enters the combustion chamber of combustion chamber fast from a plurality of through holes of combustion chamber bottom, plays combustion-supporting effect, make firepower big, burning is violent.

The beneficial effects of the utility model are: 1. because burner is provided with annular preheating cavity, after low-pressure fuel gas enters cavity, can very fast expanded by heating, air pressure is increased, gas volume increases, bigger jet power is arranged when pipeline is delivered to spit tube, can make the firepower of ejection big, the efficient height, if what be input into is liquid fuel, the very fast gasification of meeting in the burner cavity can spray from spit tube fast then, so the utility model is except burning the high pressure combustion gas, low-pressure fuel gas or liquid fuel can also burn, not only enlarge the scope of application, can also save the burning cost, reduced cost of use;

2. because the air inlet of the bottom of shaft is provided with fan, and making the cold air cavity heating between shaft and combustion chamber that enters, a plurality of through holes from the sidewall of combustion chamber enter the combustion chamber in the combustion chamber then, and good combustion-supporting efficient is arranged, help improving firepower, reduce the harmful substance in the waste gas.

[description of drawings] further specifies the utility model below in conjunction with drawings and Examples.
