Commercial Gas Stoves
Abvesta Commercial Kitchen Equipment combustion method currently used on the market continues the combustion method, that is, “post-mix combustion” (thermal engineering is called diffusion combustion).
After the hybrid combustion, that is, the side of combustion and oxygen mix, gas in the furnace combustion chamber was ignited and then turned on the fan, with a blower to the ignited gas to supply oxygen to the wind.
The low technical content results in the unreasonable structure of most stove burners, low fuel burndown rate, waste of energy and pollution of the environment.
This way of burning stoves has been going on for many years, and the state technical supervision department set the industry standard for stoves in 1999, which has a thermal efficiency of only 20% and a waste of 80%.
Advantages of commercial gas stove High stability – because gas and air are not mixed before combustion, there is no impact on both pressures and other factors.
The flame is stable, and the size flame can be freely adjusted by the valve in front of the stove.
Only the blower and stove head composed of the commercial wind blower combustion stove head, simple structure, low cost is currently widely used in the domestic commercial stove industry.
The disadvantages of commercial gas stoves Are heavily used shallow combustion chamber stove head, its depth of 30mm.
The total intake air pore volume of about 130mm, the maximum air hole up to 4-6mm, gas and oxygen can not be mixed according to the proportion required for normal combustion, so that gas can not be fully burned, forming a large number of incomplete combustion of high carbon gas from the flue exclusion, high temperature exhaust emissions, low thermal efficiency, high gas consumption.
1) the bottom of the pot from the furnace head plane distance of 200-220mm, the distance is too long, small flame can not reach the bottom of the pot.
2) The air intake hole is too large, the wind pressure wind speed is too fast, the fuel blowing to the furnace around and the flue combustion caused.
3) The amount of air intake is unreasonable, more than a certain load, is the red and yellow flame, the flame is large but weak, the partial fire dispersion is uneven, black smoke, burning is not good, sewage aggravation;
4) the depth is too shallow, the fuel stays in the combustion chamber for too short, the premix is not sufficient, the combustion flame column high temperature area is mostly carried out above the combustion chamber, coupled with strong wind blowing, resulting in heat energy being blown into the furnace flue and causing waste, fuel burndown rate, utilization rate, thermal efficiency is very low;
5) Gas can not buck the speed;
6) furnace head materials using ordinary iron, ordinary technology to make stove head, short use cycle, high maintenance costs;
Abvesta Commercial Kitchen Equipment Selection Guide
1, according to their own business premises configuration of the gas source situation (artificial gas, natural gas and liquefied petroleum gas), choose the corresponding gas source stove.
2, by observing the appearance of products to generally distinguish product quality, usually high-quality gas stove products Its specifications and certificates and other accessories complete, clear printing content, the overall structure of the product is stable and heavy, thick plate, well-processed, smooth corners without burrs, clear
identification.
3, choose a stove with less noise, noise will have a bad effect on the body, the auditory organs and nervous system will cause
damage. Chefs work in the kitchen for long periods of time, in order to reduce the impact of noise on it, try to buy low noise Abvesta Commercial Kitchen Equipment.
4, choose high-safety products, Abvesta Commercial Kitchen Equipment hot load is large, the amount of gas, if the safety is low, resulting in accidental leakage, it is easy to cause accidents.
Consumers in the purchase of Abvesta Commercial Kitchen Equipment, choose the tested qualified products, for the gas source suitability management of the city, must choose the gas source suitability test qualified products.
