Wavelet study of dynamic variations in steel and ironmaking rest gases. Potential effect on external use
The surplus energy in rest gases is an important by-product in the SSAB EMEA steel plant in Luleå. The surplus is used in a local heat and power plant. Studies have been and are being carried out to find alternative use for the high calorific gases, especially the coke oven gas. The different gas fl...
