Description
Technical Field
The invention relates to a commercial burner, in particular to a double-purification energy-saving burner for various fuels, which is used on a Chinese frying stove and a big stove.
Background
At present, the common blast type diffusion direct flame gas burner of the Chinese type frying furnace used in canteens of large, medium and small restaurants, institutional schools and military police barracks in China has the following defects;
1. Forced ventilation of the blower, incomplete mixing of the gas and the air, incomplete combustion, discharge of partial unburned gas into the atmosphere along with smoke exhaust, pollution of the ambient air, and removal of a large amount of heat;
2. the common drum-phoenix diffusion type burner needs part of secondary air to support combustion, so that the burner ring is required to be opened, flame runs off along with an opening contacted with a frying pan during combustion, otherwise, the flame is extinguished due to lack of oxygen, and therefore, the heat loss of high-temperature flame at the opening of the burner ring accounts for about 25% -30% of the total heat supplied by fuel gas. The combustion furnace ring used on the Chinese style frying furnace is not opened or semi-opened, but smoke is discharged from a smoke window in the furnace, incompletely combusted fuel gas is discharged out of the heating auxiliary furnace along with the smoke window, and the heat is taken away to account for 20% -30% of the total heat, and especially the large cooker is more outstanding.
3. The heat exchange amount of convection combustion in the combustion process is small, and the heat efficiency is low because the temperature of the hearth is not high.
4. The special purpose of gas can not be a kitchen range for multi-purpose burning liquid fuel.
From the above points, the common blast diffusion type straight flame gas combustion medium frying furnace is: the gas combustion is insufficient, resources are seriously wasted, and the waste gas which is not burnt is discharged to the atmosphere to pollute the air; secondly, it is: a large amount of heat energy is lost, so that the consumption of fuel gas is increased, and the temperature of the surrounding environment is also increased; thirdly, the method comprises the following steps: insufficient combustion leads carbon monoxide and oxynitride to seriously exceed the standard, worsens the operating environment of the kitchen and directly endangers the physical and mental health of kitchen operators.
For this reason people improve the burner of ordinary chinese style stove of frying, and publication number CN102221207A provides a commercial burner assembly, and this burner assembly is different from above-mentioned, and is structurally somewhat improved, has certain energy-conserving effect, and the furnace has set up the waste heat utilization water jacket moreover, and its characteristics are that gas and air meet in the combustion chamber directly to gas and air can preheat before entering the combustion chamber, and this kind of burner assembly has following shortcoming:
1. the burner burns in a diffusion direct flame mode, the convection heat exchange amount of flame to a frying pan is small, the temperature of the furnace wall of the hearth is not high, even if the outer wall of the hearth is provided with the water jacket, the inner wall of the hearth is provided with the high-temperature heat accumulation anti-corrosion inner sleeve which can absorb a part of heat, but the furnace wall of the hearth lacks radiant heat, water of the water jacket cannot absorb waste heat, and the temperature of the hearth can be reduced to increase fuel gas consumption.
2. The foreign matters easily block the atomization small holes of the gas preheating and dividing combustion disc, or penetrate the atomization small holes to block the gas holes and can not burn normally.
3. When the burner works, the gas preheating and dividing combustion disc is in a high temperature area, after being corroded and deformed or burned and broken at high temperature, part of atomization small holes are deformed and blocked to block the supply of mixed gas, the gas mixing amount at the broken part is increased, the mixing proportion of air and gas can be lost, incomplete combustion or unstable combustion can be caused, and the kitchen environment is polluted to influence the cooking efficiency.
4. The fuel gas preheating and dividing combustion disc has high material and manufacturing cost, short service life and high user replacement cost, and brings inconvenience for users in replacement or maintenance;
5. The ceramic plate or ceramic material product is used for heat collection of the hearth, the heat collection effect of the material is good, the service life of the water in contact with the soup is short, the use cost of frequent replacement users is high, the normal cooking time is often delayed to influence the dish output, and the normal income is reduced.
In summary, the existing burners are all diffusion type burners, and have many defects, so that the existing burners have many faults in practical application, have short service life, are often incomplete to burn, and are particularly serious when a Chinese style frying stove is used with big fire. Not only pollutes the environment and damages the human body, but also wastes a large amount of fuel gas resources, and brings economic loss to the society for users. Therefore, the research on the combustion apparatus is focused on energy conservation, environmental protection, safe and reliable use and durability, the combustion structure is improved, the heat efficiency is improved, the energy is saved, and the environmental pollution is reduced, so that the important subject of the current whole society is concerned.
