At present, the domestic Chinese restaurants, canteens used gas cookers mainly include stir-fry stove, low soup stove, cauldron stove, steamer, etc. The cookers used are blast burners (stove), which have low technical content, poor safety, thermal efficiency and use of the function has been unable to meet today's high fuel prices and chefs, catering owners, this is the main problem that the cooker industry is facing at the moment.

In recent years, by the national “energy saving and emission reduction” policy, the commercial energy-saving cooker market winds up, due to the commercial energy-saving cooker market has not yet formed a standardized route, the R & D strength of uneven, the domestic energy-saving cooker market is still in a state of confusion. With the continuous standardization of the industry, the energy-saving stove industry must have a reshuffle process. To have excellent professional knowledge and real energy-saving effect, master the core energy-saving technology in order to stand out, but also may have a place in the market.

Recognition of traditional commercial gas stove:

The commercial gas stove currently used in the market is mainly divided into three series: Guang style stove, Ning style stove and Shandong stove. However, the combustion method of each series still continues the traditional combustion method, that is, “post-mixed combustion” (thermodynamically known as diffusion combustion). Post-mixed combustion, i.e., combustion while mixing with oxygen, the gas is ignited in the combustion chamber of the stove head and then the fan is turned on, with the help of the blower blowing air to the ignited gas for oxygen supply. The status quo of low technology content leads to most of the stove burners in use in the unreasonable structure, low fuel burnout rate, waste of energy, pollution of the environment. This traditional stove combustion, has continued for many years, the national technical supervision department in 1999 to develop the stove industry standards, its standard thermal efficiency is only 20%, waste up to 80%. What makes the fuel utilization rate is so low, here there is heat radiation, heat conduction, the phenomenon of empty combustion exists.

The advantages and disadvantages of traditional commercial gas stoves are summarized below:

Advantages: high stability - due to combustion before the gas and air are not mixed, will not be affected by factors such as pressure on both sides. The flame is more stable and the flame size can be freely adjusted by the valve in front of the stove. Only the blower and the stove composed of traditional commercial air blower combustion stove, simple structure, cheap, by the current domestic commercial stove industry is widely used.

Disadvantages: shallow combustion chamber stove is widely used, its depth is 30mm, the total amount of intake holes for about 130mm, the larger intake holes up to 4-6mm, gas and oxygen can not be mixed in the normal proportion of combustion, so that the gas can not be fully combusted, the formation of a large number of incomplete combustion of high-carbon gases discharged from the flue, the high temperature emission of exhaust gas, low thermal efficiency, high gas consumption.

1、The distance between the bottom of the pot and the plane of the stove is 20mm, the distance is too long, the small and medium-sized flame can not reach the bottom of the pot, resulting in waste.

2、The air inlet hole is too big, the wind pressure and wind speed is too fast, the fuel will be blown to the flue and flue around the stove to burn causing waste.

3, into the wind is unreasonable, more than a certain load, then the flame red and yellow, fire and powerless, partial fire dispersion is not uniform, black smoke, bad combustion, sewage aggravation.

4, the depth is too shallow, the fuel in the combustion chamber residence time is too short, premixed insufficient, combustion flame column high temperature area mostly in the combustion chamber above, coupled with strong winds blowing, resulting in heat is blown to the furnace flue and wasted, the fuel burnout rate, utilization rate, thermal efficiency is very low.

5、Gas can't reduce pressure and speed.

6, the stove head material is made of ordinary iron, ordinary process of making the stove head, the use cycle is short, high maintenance costs;

7, at the same time, due to the traditional stove for a long time open fire (i.e., using a large fire) and the existence of high-temperature heat conduction, heat radiation, resulting in a large amount of gas is wasted.
