Abstract

A method and system for determining a mass and energy balance for a glass furnace proceeds through a furnace model and calculates a number of parameters for the flows within each segment of the furnace. The mass flow rate, enthalpy, and enthalpy flow rate of each mass flow entering a segment is found and then the enthalpy and temperature of the unreacted mixture is determined. Based on an assumption that the flows entering a segment combust completely and instantaneously, the enthalpy, enthalpy flow rate, mass flow, composition, and temperature of a reacted flow exiting the segment is determined. If the furnace implements reburning, then the mass flows for the furnace are adjusted. Also, the mass and energy for each flow can be determined if the furnace has a regenerator, a recuperator, or a reburning system. Further, the mass and energy for each flow can be determined for a wide range of furnace types.
