Furnaces fundamentally serve to supply a specified quantity of heat to process fluids. Together with steam boilers they consume approximately 75% of the energy used at petroleum refineries or chemical processing plants. An important factor in the overall efficiency of a furnace is the transfer of thermal energy between the furnace tube and the process fluid.
