  • CHARACTERISTICS OF OXYFUEL AND AIR FUEL

    2015-3-26 · The characteristics of oxyfuel combustion are compared to those of air-fuel combustion in the furnace of a typical industrial water tube boiler. Two oxyfuel cases are considered. These correspond to 21% O 2 and 29% O 2 by volume. Validations for both oxyfuel combustion and air-fuel combustion indicate that the temperature levels are reduced in

    Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.
