A two-year (1996-'97) investigation into the use of three different combustion technologies for the production of heat in a variety of applications in the power and process industries has been excuted under a research program consequently named "Compact Fired Heating Units". These three state-of-the-art technologies are respectively fully premixed swirling combustion, air staged combustion and flameless oxidation combustion. Key features of this research are: the use of medium to high preheated combustion air to increase the thermal efficiency of those appliances where the flue gas exhaust temperature is higher than 300 oC; the enhanced use of NOx abatement strategies such as in-furnace flue gas recirculation and/or air-fuel staging; and the use of the potential for increasing the firing intensity of furnaces and process fluid heaters in order to reduce the volume and floor space when needed.
