Blast furnace gas burners are designed primarily for the combustion of blast furnace gas generated by steel companies. They are suitable for blast furnace gas of any pressure and calorific value. Utilizing multi-head internal mixing technology, these burners offer stable combustion and include automatic ignition, flameout protection, and automatic power adjustment. They require no firewood for heat storage and are easy to use. They are now widely used in steel companies and related enterprises.
Performance characteristics:
1. The calorific value of the fuel type is low, about 700-900Kcal/Nm³, and it is not easy to ignite.
2. There is no requirement for fuel pressure, and the given value can be designed and produced before ordering, usually the gas design pressure is 5-8KPa.
3. It is usually used on negative pressure combustion furnaces.
4. Control systems such as section fire type, damper adjustment proportional type, frequency conversion adjustment proportional type, touch screen digital control, and industrial computer frequency conversion proportional control can be configured according to user requirements.
5. Separate channel control of gas and damper, using online setting of wind/air ratio K value, accurately control the wind/air ratio to prevent errors caused by connecting rod transmission.
6. Equipped with flame extinguishing protection, automatic ignition, valve leak detection, over-temperature and over-pressure protection, status parameter display and other functions.
7. The control system follows the standard communication protocol and can communicate with the user's upper system.
8. Remove the automatic control system, manual combustion can be normal, and it is very easy to adjust.
