1. Converter Gas Composition

During the steelmaking process in a converter, the carbon in the molten iron reacts with the injected oxygen at high temperatures to produce a mixture of carbon monoxide and a small amount of carbon dioxide. Converter gas contains 60-80% carbon monoxide, 15-20% carbon dioxide, and nitrogen, hydrogen, and trace amounts of oxygen.

The calorific value ranges from 6800-10000 kJ/m³. Its ignition temperature is 530℃, and the explosion limit is 18.2%-83.2%. The CO content is as high as 60-70%, and the toxicity is relatively high. Converter gas is considered a medium-calorific gas fuel, which can be used alone for combustion in industrial kilns or mixed with other gases such as coke oven gas, blast furnace gas, or producer gas to form mixed gases with different calorific values for use.

2. Converter Gas Control Characteristics

1. High calorific value of fuel type, approximately 6800-10000 kJ/m³. The main component in the mixed gas is CO, which burns quickly.

2. No fuel pressure requirements; the given value before ordering can be used for design and manufacturing. The typical gas design pressure is 5-15 KPa.

3. Control systems such as segmented fire type, damper adjustment ratio type, frequency conversion adjustment ratio type, touch screen digital control, and PLC frequency conversion ratio control can be configured according to user requirements.

4. Separate channel control of gas and damper. Online setting of air/gas ratio K value is adopted to accurately control the air/gas ratio and prevent errors caused by connecting rod transmission.

5. Functions such as flame detection and flameout protection, automatic ignition, valve leak detection, overtemperature and overpressure protection, and status parameter display are configured.

6. Mainly used in boilers, dryers, hot blast stoves, incinerators, and rotary kilns.
