Plasma Recycling System for Heating Furnaces - Energy
About 20% of the CO2-emissions in the steel industry can be ascribed to furnace heating processes. The industry estimates that a large share of the furnaces can be electrified to reduce the use of fossil fuels, and one solution is electrification with plasma technology. Using plasma heating, the steel industry will have cost-effective solutions and a faster transition towards green technology.
Another application in steel industry is pre-heating of steel plant ladles. Pre-heating is required to minimize thermal shock and damage of refractory lining. Standard heating technologies combust fuels in an oxidizing environment, causing wear of refractory already in the heating procedure. Using plasma technology enables pre-heating in inert atmosphere, reduces use of fossil fuels and CO2-emissions.
