Modeling of Heat Flux in a Heating Furnace

Modern heating furnaces use combined modes of the charge. At high temperatures, more radiation is used; at lower convection used. In large furnaces, such as pusher it necessary to monitor material zonally. Zonal allows appropriate thermal regime be set in each zone, according desired parameters for The problem furnace optimum so that end heating, after has been cross-sectioned, there a uniform temperature field with minimum differential. order evaluate charge, mathematical model was developed calculate heat fluxes moving charge (slabs) along length furnace. obtained results are based on experimental measurements test slab which thermocouples were installed, and data acquisition provided by TERMOPHIL-stor logger placed directly slab. Most models focus only energy balance assessment or external exchange. from created showed reserves changing regimes different zones. used compare evaluation slabs rebuilding Changing altering zone contributed reduction specific consumption. flux applicable part powerful tools monitoring controlling condition inside well evaluating operating furnaces.
