    Abstract:

    Melting and heating of metals are very energy intense processes. Conventional combustion with air with high nitrogen amount is affecting energy consumption and heating rates of such processes. Combustion with oxygen instead of air will reduce heat losses and improve process conditions. Oxyfuel flames have the tendency of generating hot spots in furnaces and combustion chambers. This paper will discuss the effects that flameless combustion will have on heating and melting with practical examples. It will also give some information about safety.
