Abstract

Method and apparatus for continuation of combustion with an oxy-fuel combustion system when the supply of oxygen is temporally reduced or stopped. Air or oxygen enriched air and fuel are introduced into the device being heated in place of the oxy-fuel mixture to effect combustion and maintain the heating level in the furnace. Water cooling of the furnace gases is used to reduce the volume of exhaust gases when operating in the air or oxygen enriched air mode.
