Blast furnace gas burner: dryer burner, boiler burner, hot air stove burner

The blast furnace gas burner is mainly designed for the combustion of blast furnace gas produced by steel enterprises, also known as the blast furnace gas burner. This burner adopts (single) multi head internal mixing technology, with built-in ignition nozzle, commonly known as: long open flame small gun, ignition small gun, and guide fire small gun. It uses high calorific value fuel (natural gas, liquefied petroleum gas) as the fuel. The small nozzle is first ignited, and after the liquefied gas ignition nozzle burns stably, the main gas nozzle (i.e. blast furnace gas nozzle) is automatically switched to prevent a large amount of blast furnace gas from accumulating. Once encountering an open flame, the phenomenon of "explosion" occurs, Applicable fields of blast furnace gas burners: industrial furnaces, rotary kilns, dryers, hot air furnaces, fluidized bed furnaces, dryers, rotary kilns, and boiler equipment.

Performance characteristics of blast furnace gas burner:

1. The fuel type has a low calorific value, approximately 700-900Kcal/Nm ³， It is not easy to ignite, and high calorific value fuel is usually used as a pilot or open flame ignition method.

2. The blast furnace gas pipeline needs to be pressurized to 5-15KPa to prevent pipeline backfire, and a fire resistance device and gas release device are designed.

3. Usually used on negative pressure combustion furnaces.

4. According to user requirements, control systems such as section fire type, damper adjustment proportion type, frequency conversion adjustment proportion type, touch screen digital control, and industrial computer frequency conversion proportion control can be configured.

5. The gas and damper are controlled through separate channels, and the air/gas ratio K value is set online to accurately control the air/gas ratio and prevent errors caused by connecting rod transmission.

6. Equipped with functions such as flame detection and flameout protection, automatic ignition, valve leakage detection, overtemperature and overpressure protection, and status parameter display.

7. The control system follows standard communication protocols and can communicate and connect with the user's upper system.

8. Remove the automatic control system, manual operation can burn normally and is easy to adjust.

9. The valve group of blast furnace gas burner adopts explosion-proof pneumatic shut-off valve or regulating valve, which can achieve automatic control function based on temperature.

10. Blast furnace gas can be mixed with converter or coke oven gas to increase the calorific value of blast furnace gas. It can also be improved by using oxygen rich or pure oxygen combustion technology to enhance the theoretical combustion temperature and better use.
