I. Introduction Zhengzhou honor heat Technology Co., design and production of natural gas burner, energy saving, high speed and efficiency, combustion flame, no tempering off the fire phenomenon, adjustable ratio up to 1:10, smoke emission standards for forging furnace, heat treatment furnace workpiece, mold roaster and other types of furnaces, conventional models 150kw, 230kw, 320kw, 450kw, 630kw, 1000kw can be customized according to customer non-standard furnace conditions, support cash settlement, burner installation and provide technical support and system design two, burners feature a brief introduction, definitions and principles burner burner simply defined as installed in the furnace kiln burner. The most commonly used burners the burner or furnace for the low-speed sub-high-speed burner, high-speed burner is characterized by the burner combustion gas exit velocity up to 80 m / sec or more, the combustion air through the outlet of the combustion gas temperature and heating the workpiece is reduced to a temperature close to the temperature. High-speed burner heat to promote its high-speed air circulation furnace, furnace temperature uniformity reduces the temperature difference between the flame and the workpiece, effectively improve the thermal efficiency furnace 2, the technical parameters of gas burners varieties: natural gas, liquefied petroleum gas pressure: Natural gas LPG combustion air pressure 5KPa 5.0--6.0 KPa maximum gas flow rate: 100 m / s burner turndown ratio: 1:10 Noise level: in line with national standards and burner-related characteristics 3. Tempering: flame propagation speed over fuel When the air mixture through the nozzle velocity, the phenomenon of the burner flame propagating inside called tempering. Tempering tempering generally produce noise, hot back-ming. Severe burn interrupted. Pre-mixed and semi-premixed burners will have tempered dangerous. External mixing burner, fuel and air in the burner external mixing, tempering phenomenon does not occur. Off the fire: stable combustion requires a stable point, that the flame is continuously lit area. A mixture of fuel and air flow rate exceeds the flame propagation velocity caused by the flame from the stable point called off the fire. The greatest threat to stability is off the fire burning, fire off is usually the main cause of the flame extinguished. Third, the burner flame combustion and therefore the selection conditions, the flow rate of flame and combustible gas mixture equal and opposite direction, which is why we have been studied at critical points, through large amounts of data and experimental tests have basically found a relatively reasonable ranges, and applied in a variety of furnace conditions, Hebei burner market, Henan burner market, Shandong burner, etc. are well reflected in the market. At this point, honor companies pay more attention to flame design, look for energy-efficient gas burner under the premise of combustion burner safety, and hope you expert guidance, ask for their valuable advice with customers. According to customer kiln, the calorific value of the fuel, the gas pressure is different in different design specifications burner, gas burner, gas burner, industrial furnace burner, low-speed burner, energy-saving gas, affordable is our common desire
