Steady and Transient Thermal Analysis of the DWPF Melter Operation

PDF Version Also Available for Download.

Description

At HLW Division's request, an analysis has been performed of power usage at characteristic times in the Defense Waste Processing Facility production. For the first time in the Department of Energy complex, a program has been developed permitting the monitoring or systematic categorizing of power and heat distribution in an operating waste glass production melter. To date, the Defense Waste Processing Facility Melter power and heat trends have been analyzed in terms of individual or total power sources. The method applied here provides a steady state balance between melter power inputs and various heat losses under continuous feeding/pouring or idling ... continued below

Description

At HLW Division's request, an analysis has been performed of power usage at characteristic times in the Defense Waste Processing Facility production. For the first time in the Department of Energy complex, a program has been developed permitting the monitoring or systematic categorizing of power and heat distribution in an operating waste glass production melter. To date, the Defense Waste Processing Facility Melter power and heat trends have been analyzed in terms of individual or total power sources. The method applied here provides a steady state balance between melter power inputs and various heat losses under continuous feeding/pouring or idling conditions. Power comes from two electrode circuits and separately controlled dome heaters. Heat energy is lost through the melter shell, as well as evaporation of water, heating of steam and in-leakage air, chemical reactions, and heating of glass. These various power consumption pathways are not constant and depend on melter operation, such as feed rate, solids ratio, feed batch and net melt pool circulation. The analysis uses the lumped parameter approach to sum the power inputs and proportion them to the various power uses, providing an overall perspective of the power distribution. Through the analysis of a practical melt rate model (personal computer based), the separate effects of engineering and physico-chemical batch effects can be obtained for quick evaluation of their effects on melt rate. The thermal model provides the framework where laboratory determination of batch effects, e.g., specific heat, viscosity, thermal conductivity, etc., can be fed in and the melt rate predicted.
