Combustion Modeling In Large Gas-fired Furnaces
Abstract
Recent literature that applies to modeling turbulent reacting flow fields in the primary and secondary combustion zones of large gas-fired furnaces shows that three characteristic times the chemical reaction time, the eddy breakup time, and the molecular mixing time are important in modeling turbulent-reacting flow. Combustion modeling in large furnaces is classified as: (1) empirical, (2) modular, and (3) fundamental. Empirical models predict overall characteristics, but cannot be readily extended from one furnace to another. Modular models predict the stability and residence-time distributions (macromixing); however, they do not predict the correct temperature-time history of the flow (micromixing). Fundamental models involve solving the complete set of conservation equations. The equations are three-dimensional and time dependent and they have not been solved for the exact conditions existing in furnaces. © 1979.
