A Study of Exergy Analysis for Combustion in Direct Fired Heater (Part I)

Heat transfer plants with organic media have often been able to replace or improve the classic steam-water operation. The possibility of transferring and closely controlling temperature up to > 300°C has provided the heat transfer media technology with many new fields of application. This growing application of heat transfer plants with liquid heat transfer media other than water has made it necessary to produce complete and accurate engineering database for combustion and its devices to continuous improvement of industrial heating. Heating is an important operation in almost all industrial fields. A large variety of heating techniques is available at the market. Some examples are fuel burning, electrical heating, and so on. The analysis of related combustion process and estimation of the effective coefficients is the first step toward a successful design. The process of combustion fuel and their combustion and combustion devices are considered in this study. Direct fired heater exergy and energy analysis are performed taking into account precise calculation of chemical exergy for products of combustion.
