Energy efficiency in practice

Energy efficiency applies to the whole production chain and the need for purchased fuels is reduced by optimizing which process gases can be utilized for which processes. Additionally, the production of electricity and heat is maximized in terms of heat value and volume by optimizing the supply of process gases to the power plant. The most fundamental part of improving energy efficiency is to constantly question if energy usage is optimized, as well as analyzing the actual need in different processes (shutdowns, different production levels, etc.). Below are some examples of activities to improve efficiency, based on experiences from SSAB’s operations and split into optimization, productivity, use and maintenance.
