Reducing excess air in the kiln is an important way to reduce energy consumption, but maintaining a reasonable working state of hundreds of burners is also the basis for energy saving. Partition regulation can keep the air-fuel ratio of the whole area in a reasonable range, and the regulation of a single burner becomes an almost impossible work on site due to the huge workload.
A- UTO automatic adjustment burner for a special burner can automatically control the air-fuel ratio, can ensure that each burner can maintain the best combustion state. The power of the burner is 5-60KW, driven by the gas pressure, and the air-fuel ratio is preset. After that, the burner will automatically match the corresponding air flow according to the gas flow. The maximum service temperature of combustion-supporting air is 250 degrees, the air-fuel ratio can be adjusted, and the minimum opening degree can be adjusted. After the one-time adjustment is completed, it can run automatically.
A- UTO automatic adjustment burner can also be assembled and used together with silicon carbide, and preheated air (below 250C) can be used.
Energy saving Due to the high temperature of the oxygen-enriched combustion flame, the temperature and pressure in the furnace increases, and the radiation heat exchange enhances the effective use of heat in the furnace, thus saving fuel consumption. The adjustment ratio is large, the flame is stable, and the temperature of the fire tube and the nozzle can be effectively controlled to extend the life. Large range of oxygen content
With the increase of oxygen content in oxygen-enriched air, the theoretical air volume decreases, thus changing the combustion characteristics of flame temperature. High flame temperature increases with the increase of oxygen content in oxygen-enriched air. Generally, it is appropriate to control the oxygen content below 28%.
When the oxygen content of oxygen-enriched air increases from 21% to 27%, the heat loss of exhaust gas can be effectively reduced. As the temperature of flue gas increases, the heat of decomposition increases, which is one of the reasons why the oxygen-enriched combustion flame has a large heat transfer capacity.
As the output of modern tunnel kiln and roller kiln is getting bigger and bigger, the kiln body is getting wider and longer, only increasing the burner power and the number of burners on the original kiln body will cause the deterioration of the air flow in the furnace, the imbalance of the pressure control in the furnace, the poor uniformity of the furnace temperature, and the high content of nitrogen oxides in the combustion products, which has great pollution to the environment. The A- IFGR reflux low-nitrogen burner effectively solves the problem of the ceramic burner in the prior art, and provides a reflux ceramic burner, which realizes multi-dimensional three-dimensional circulation of flue gas in the furnace, improves the uniformity of furnace temperature, improves the control of furnace pressure, reduces the flame temperature, inhibits the generation of nitrogen oxides, reduces nitrogen oxide emissions, improves heating quality, and reduces energy consumption.
Industrial furnaces for high temperature heating (above 900°C) and melting applications mostly use gaseous fuels, such as natural gas. When ambient air (especially preheated air) is used as the oxidant, the gaseous flame is usually blue and has a very low luminosity (emissivity), thus reducing the heat exchange between the flame and the furnace contents. In contrast, in many cases, a luminous oil flame is produced, which can reduce fuel consumption by up to 25% and reduce exhaust gas temperature due to its strong heat radiation properties. Therefore, in the case of high temperature heating, the combustion of gaseous fuel to produce a bright flame with high radiation capacity (called glow flame) has important technical and economic value. A- BF flame burner uses a unique patented technology to achieve high thermal emissivity, high brightness reduction flame (or oxidation flame)
