I. Burner Product Features

　　1. High combustion efficiency, blue flame, and all parameters of combustion products meet national standards.

　　2. The flue gas ejection speed can reach more than 100m/s. Different burner bricks can be used according to user requirements to obtain different flue gas ejection speeds.

　　3. Small power adjustment range, low noise, no flashback, no blow-off, high safety.

　　4. The burner head uses high-temperature materials, with advantages such as long service life and no rust.

　　5. According to the flame characteristics and industrial furnace heating process requirements, Zhongwei Company can design: straight flame burners, flat flame burners, high-speed burners, etc.

　　6. The burner has a built-in dual-electrode structure, with automatic ignition and flame detection functions. When used with an automatic igniter and detection controller, it can achieve kiln temperature self-control and safety control.

　　II. Explanation of the structure and principle of high-speed temperature-regulating burner as an example

　　The characteristic of the high-speed temperature-regulating burner is that the outlet speed of the combustion gas of the burner can reach more than 100 meters per second. By introducing secondary air, the temperature of the outlet combustion gas is reduced to a temperature close to the workpiece heating temperature. Therefore, the use of high-speed temperature-regulating burners can strengthen convective heat transfer, promote uniform furnace temperature and airflow circulation, reduce the temperature difference between the flame and the workpiece, and is beneficial to improving workpiece heating quality and energy saving.

　　IV. Instructions for Use

　　The fuel used by the burner is various fuel gases, and its rated calorific value is shown in the table. When selecting the burner model, calculate the burner energy (standard cubic meters/hour) according to the actual low calorific value of the fuel gas used, and then select the burner model.

　　When the burner inlet gas pressure is lower than 3.5 KPa (producer gas, coke oven gas) and 5.0 KPa (natural gas, liquefied petroleum gas), the burner energy is calculated according to the following formula:

　　V1=sqr2{P2/35(50)}V (standard cubic meters/hour) where P2 is the actual pressure value (KPa)

　　V is the burner energy at the rated inlet gas pressure. The rated pressure of the producer gas and coke oven gas burner is 3.5 KPa, and the rated pressure of the natural gas and liquefied petroleum gas burner is 5.0 KPa.

　　V. Scope of Application

　　Applicable industries: metallurgy, chemical industry, ceramics, glass, refractory materials, building materials, papermaking, medicine, etc.

　　Applicable kiln types: tunnel kilns, roller kilns, heating furnaces, quenching furnaces, annealing furnaces, hot air furnaces, boilers and other industrial kilns.
