The power of heat recuperation
Flue gases are passed through a recuperator to preheat fresh combustion air
Pre-heated air provides for higher melting efficiency
Exothermic reaction occurs in the recuperator transforming carbon monoxide into carbon dioxide
Flue gas emissions are reduced by 70% compared to coke
Higher tacit efficiency and lower emissions than electric melting when considering factors for producing electricity from fossil fuel for melting
Higher tacit efficiency and lower emissions than hot blast and cold blast cupolas
( Left) The use of natural gas leads to very low emissions in ppm
