With the wave of energy revolution of oil to gas and coal to gas spreading across the country, the low consumption, environmental protection and other quality fuel characteristics of clean energy such as natural gas gradually show strong market competitiveness. Natural gas burners, low-NOx burners, etc. have gradually become the mainstream of the burner market.
The main fuel of gas burner is natural gas, liquefied petroleum gas, city gas and other combustible gases, these fuels are flammable and explosive dangerous gases, in the use and storage process should pay great attention to safety, otherwise major safety accidents will occur. Therefore, the use of gas burners need to be rigorous and careful.
According to the shape of the flame when the burner is in use, we can further subdivide the gas burner into flameless burner, flat flame burner and combined burner.
Flameless burner
The burner in which the gas and all the air required for combustion are premixed and the flame of the combustion process is short or even completely invisible. Generally, the air is sucked in by the pilot, and is fully premixed with the gas, and the combustion is completed instantly in the high-temperature fire channel. The thermal intensity of the fire channel is high, and the combustion temperature is also high. Flameless burners are widely used in industrial heating and drying processes.
Flat flame burner
The flame is a flat shape gas burner. Figure 2 shows a double-spin flat flame burner. The air and gas flow out separately through the cyclone, and the two are strongly mixed in a cyclonic state and then enter the flare flame channel for combustion. Due to the centrifugal force of the airflow and the wall effect, a flat flame is formed at the exit of the fire escape. This kind of burner has uniform temperature, heats up faster and can save gas, but the technical requirements for processing and installation are higher.
The construction of a resource-saving and environment-friendly society is in full swing, and the emission control of air pollutants is being promoted in an orderly manner. Compared with coal and oil burners, gas burners are more suitable for the future development trend of green environment protection. The gas burner is widely adaptable to natural gas, LPG, biogas, coke oven gas, etc., to meet the demand of manufacturers for gas burner customization needs!
In order to target the suppression of large amounts of nitrogen oxide emissions, the need for environmental technology reform of the boiler, which plays an important role in ultra-low nitrogen burners....
