Best technology solutions for steel industry
Blast furnace, coke oven and natural gas
In the steel industry, in-house-produced gases such as blast furnace gas, coke oven gas and natural gas are used for power generation and heat treatment processes.
Fluctuating gas compositions present a challenge to combustion control and gas blending. The WIM COMPASTM measures the Wobbe Index, heating value, specific gravity and Combustion Air Requirement Index of these fuel gases in a steel plant.
The above-mentioned parameters can be used to reach complete combustion, or to generate a stable oxidizing or reducing oven atmosphere. The close-to-real-time analyzer keeps the process under control. For installations with multiple small burners operating under varying fuel gas quality, automatic control is not possible. The gas stabilization system can be installed at the plant inlet, providing stable gas to the plant. This gas-blending package mixes fluctuating fuel gas with air or another auxiliary gas to form a stable gas, feeding each individual burner. This complete, engineered and tested solution is easy to install at an existing plant, and provides a good furnace atmosphere under fluctuating fuel gas quality.
