Gas furnaces nozzle nozzle

Environmental pressures, market competition, forcing companies to replace fuel in industrial furnaces, especially in recent years under the pressure of energy and environmental protection, fuel replacement is a very common phenomenon, generally mistaken for exchange only in accordance with the ratio of the calorific value of the fuel the supply of conversion can be performed, resulting in improper kiln burner selection, power is too small production capacity of less than expected, serious waste heat power is too large, increasing the cost of doing business. In fact, the replacement of the fuel is not a simple calculation of calorific value than that of the fuel combustion efficiency, heat fuel efficiency, fuel and combustion air is preheated furnace heat circulation, and other conditions. I. Introduction Zhengzhou great honor to heat Technology Co., Ltd. design and production of natural gas burner, energy saving, high speed and efficiency, flame stability, no tempering fire off phenomenon can be adjusted ratio of 1:10 and smoke emissions 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 on delivery settlement, and provide technical support burner installation and system design II Introduction 1 burner characteristics, definitions and principles burner burner simple definition to be installed in the furnace kiln burner. Currently used as a low-pressure furnace burners on high-speed burner or sub-high-speed burner, is characterized by high-speed burner burner combustion gas exit speeds of up to 80 m / sec or more, the combustion air by the outlet of the combustion gas temperature workpiece heating temperature is reduced to 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 5.0--6.0 KPa 5KPa maximum gas flow rate: 100 m / s burner turndown: 1:10 Noise level: compliance with national standards and burner-related characteristics 3. Tempering: flame spread faster than fuel air mixture through the nozzle velocity, phenomena inside the burner flames to spread is called tempering. Tempering temper generally produce noise, back hot 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: a stable combustion requires a stable point, the flame is continuously lit area. Fuel and air mixture flow rate exceeds the flame propagation speed caused by the flame from a stable point called off the fire. The greatest threat to the combustion stability is off the fire, from the fire is usually the main cause of the flame extinguished. Third, the burner flame selection therefore stable combustion conditions, the flow rate of combustible gas mixture of flame and equal and opposite directions, which is the key point in the research we've been through a lot of data and laboratory tests have basically found a relatively reasonable the range and applications in a variety of furnace conditions, Hebei burner market, Henan burner market, Shandong burner markets are well represented. At this point, great honor company pay more attention flame stable design, look for energy-efficient gas burners Safety burner combustion under the premise, but I hope that the expert guidance, ask for their valuable advice with the customer. According to customer kiln, the fuel heating value, different designs of different sizes burner gas pressure, gas burner, gas burner, industrial furnace burner, low-speed burner, energy-saving gas, affordable is our common aspirations
