Commercial gas cooker awareness of traditional commercial gas cooker advantages and disadvantages

In recent years, by the national "energy saving and emission reduction" policy, the commercial gas cooker market is gradually known to the public. Due to the emerging commercial gas cooker market has not yet developed a standardized industry standards, as well as the R & D strength of various companies are mixed, the domestic commercial gas cooker market is still in a state of confusion. With the continuous standardization of the industry, the commercial gas stove industry must have a development process. Next, follow the editor to see commercial gas cooker about the content it.

One, the traditional commercial gas cooker awareness

Currently on the market using commercial gas cooker is mainly divided into three series: wide range of cookers, ning style cooker and Shandong stove. But each series of combustion is still the continuation of the traditional combustion method, that is, "post-mixed combustion" (thermotechnology known as diffusion combustion). After mixed combustion, that is, while burning and oxygen mixing, gas combustion chamber in the stove head is ignited and then open the fan, with the blower to the ignition of the gas to the wind for oxygen. The state of low technology leads to most of the stove burners in use in the structure of the unreasonable, 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 is a thermal radiation, heat conduction, the phenomenon of empty burning exists.

Two, the traditional commercial gas stove advantages and disadvantages

1, the advantages: high stability - because the gas and air in the combustion before the lack of mixing, will not affect the two sides of the pressure and other factors. Flame is more stable, the size of the flame can be freely adjusted through the valve in front of the stove. Only the blower and the stove composed of traditional commercial air blower combustion stove, simple structure, low cost is currently widely used in the domestic commercial stove industry.

2, shortcomings: the shallow combustion chamber stove is widely used, the depth of 30mm. the total amount of air inlet holes 130mm or so, the largest holes up to 4-6mm, gas and oxygen can not be mixed according to the normal combustion ratio, so that the gas can not be fully combusted, the formation of a large number of incomplete combustion of high-carbon gases from the flue to exclude, the high-temperature exhaust emissions, thermal efficiency is low, the gas consumption is high.

1) the bottom of the pot from the stove plane distance of 200-220mm, the distance is too long, small and medium-sized flames can not reach the bottom of the pot, resulting in waste;

2) air inlet holes are too large, the wind pressure and wind speed is too fast, the fuel will be blown around the stove and flue combustion caused by the waste;

3) into the wind is not reasonable, more than a certain load, it is a red and yellow flames, fire, but big but powerless, fire dispersion Uneven, black smoke, bad combustion, sewage aggravation;

4) depth is too shallow, the fuel in the combustion chamber to stay too short a time, premixed insufficiently, combustion flame column high temperature area most of the combustion chamber above the combustion chamber, coupled with a strong wind blowing, resulting in the heat is blown to the furnace flue and waste, fuel combustion rate, utilization rate, thermal efficiency is very low;

5) gas can not be bucked rumble speed;

5) gas can not be bucked rumble speed.

6)The stove head material using ordinary iron, ordinary technology to make the stove head, the use of short cycle, high maintenance costs;

7)At the same time, due to the use of traditional stove long open flame (i.e., kindling) as well as the existence of high-temperature heat conduction, heat radiation, resulting in a large amount of gas is wasted.

How about, according to the editor's detailed introduction, readers are not more profound understanding of commercial gas cookers? For the future in life when encountering such problems, I hope readers can recall having read such an article, so as to create a more perfect home environment. Thank you for readers to read this article and the editor's strong support and love, if you want to get more home furnishing information, please continue to pay attention.
