Abstract . Increasing energy costs have led to heightened interest in energy conservation and more recently in the use of "alternate" fuels. Alternate fuels are considered to be fuels not normally encountered in plant operation and in addition have a low cost. Many alternate fuels meet the criteria of low cost but create other problems. An example is the use of coke as a fuel. Sulfur, fixed nitrogen and ash are often present in quantities that create significant environmental problems. These impurities coupled with incomplete combustion will create significant fouling of the heat transfer surfaces which in turn will reduce efficiency. Alternate fuels that usually do not create the above mentioned problems are gases that have high volume percentages of inert components such as water vapor, carbon dioxide and nitrogen. Often gases of this type have been considered to be wastes and have been vented to the atmosphere, flared or burned in an incinerator. Since many of these gases do not contain impurities that lead to pollution and heat transfer surface fouling, they can be used to fire conventional process heaters and boilers. However when these gases are used as a fuel, certain characteristics must be considered and properly compensated for in the design of the combustion equipment and process heater or boiler. Some characteristics that must be considered are: high volume flow rate of fuel and combustion products, low flame temperature, limits of flammability, and increased combustion volume.
