Problems solved by technology

This kind of burner has been widely used in Chinese cooking stoves and large pot stoves. Its main feature is the constant flame, which has a large firepower, but the gas used to keep the constant flame should not be too small. It is easy to extinguish the flame after it is small, and it is easy to extinguish after the damper is closed. , mainly because there is no air to support combustion and flameout due to lack of oxygen, the thermal efficiency of this kind of burner is still low
There is also a Chinese gas stove burner disclosed in Chinese patent 200410023147.9, the manufacturing process is complicated, and it is not easy to maintain
There is also a high-efficiency energy-saving Chinese food cooking stove disclosed in Chinese patent 200510028561.3, which utilizes waste heat flue gas to preheat the mixture of fuel and air to increase thermal efficiency, but it uses a traditional burner, which increases thermal efficiency. High and difficult to maintain

Embodiment 1

[0057] As shown in Figure 1, this embodiment is an inverted trumpet-shaped externally constricted preheater, a small trumpet-shaped refractory ring, a common forced premixed small fire under the burner cover, automatic electronic ignition, air disturbance mixing, two Secondary oxygen, gas-air linkage adjustment high-speed burner. The burner is composed of a burner casing 10 , an annular distributor 6 , and a burner lower cover 24 . The lower burner cover 24 and the annular distributor 6 are integral parts, the annular distributor 6 is sleeved into the burner casing 10, and the lower burner cover 24 is fixed on the burner casing 10 by bolts 23, and the bolts 23 are preferably different. The rusted material can be used for a long time and is easy to disassemble and assemble. This connection is convenient to take out the annular distributor 6 from the burner, so as to facilitate maintenance and remove the sundries falling into the burner. The burner casing 10 and the annular dis...

Embodiment 2

[0071] As shown in Figure 2, this embodiment is an inverted trumpet-shaped externally constricted preheater, a large trumpet-shaped refractory ring, a forced premixed small fire on the bottom of a drum-shaped mixer, a fully automatic electronic ignition, and an air premixed type. , Secondary supplementary combustion, gas-air linkage adjustment high-speed burner. The burner consists of the burner casing 10 , the drum mixer 57 and the burner lower cover 24 . The burner housing 10 and the lower burner cover 24 are one piece. The bottom surface 59 of the cylindrical mixer of the cylindrical mixer 57 has ventilation holes 58. The ventilation holes 58 are porous in any direction, preferably evenly arranged in a fan shape. The ejected gas is formed into a swirling gas. There is a cylindrical protrusion 60 in the center of the lower surface 59 of the drum-shaped mixer. The cylindrical protrusion 60 is sleeved or screwed with a fire distributor 7. The fire distributor 7 is provided w...

Embodiment 3

[0076] As shown in Figure 3, this embodiment is an inverted trumpet-shaped externally constricted preheater, cylindrical refractory ring, forced premixed small fire under the burner cover, semi-automatic electronic ignition, and air premixed high-speed burner. A gas nozzle 55 is fixed on the intake pipe 3 of the first embodiment, and the lower end of the gas nozzle 55 is connected to the main fire gas pipe 19 through a gas swivel head 56 . The electronic ignition is semi-automatic electronic ignition, and the electronic ignition controller 34 is a pulse controller. As shown in Figure 28, rotate and press the handle of the small fire gas valve 20, the electronic ignition control line 22 can be connected through the electronic ignition controller switch contact 136, the electric needle 37 is discharged, and after the small fire is ignited, the small fire is released. Fire the handle of the gas valve 20, and the electric needle 37 stops discharging. This ignition method is simpl...

Abstract

The invention is a high-efficiency, energy-saving and high-speed burner for a gas cooker used in catering industry and includes a burner, a pre-heater, a pre-mixing small fire burner, a fireproof fire ring, an electronic ignition system and a regulating device. After being necked down, the burning flame is ejected with high speed rotation to form the rotary rapid ejection burning flame, thereby realizing sufficient burning, facilitating boiler heating, and increasing the heating speed with low burning noise and high heat efficiency. The high-efficiency, energy-saving and high-speed burner for the gas cooker has the advantages of simple manufacture, easy maintenance, sufficient burning, high flame temperature, convenient boiler heating, improved heating speed, low power of the equipped blower fan, low burning noise, high thermal efficiency, convenient regulation, full-automatic ignition, concentrative firepower, intensive fire, energy conservation, strong adaptability, capability of meeting different requirements, wide application, easy processing, low manufacture cost and suitability for mass production.

Description

technical field [0001] The invention relates to a high-efficiency energy-saving high-speed burner, in particular to a high-efficiency energy-saving high-speed burner for gas stoves used in the catering industry. Background technique [0002] At present, the blast-type cooking stoves or large pot stoves used for cooking food in the catering industry, the burner uses gaseous fuel to reach the combustion area and is forcibly mixed with the air sent by the blower before burning. This combustion method has strong firepower. The food is fast, but the adjustment is inconvenient, the open flame is unstable, the thermal efficiency is low, the energy is wasted and the environmental pollution is serious. Another example is a gas stove burner disclosed in Chinese Patent No. 99230474.1. This kind of burner has been widely used in Chinese cooking stoves and large pot stoves. Its main features are long open fire and large firepower, but the gas to keep the long open fire should not be too...
