Heat Management Strategies For Msw Landfills, Nazli Yesiller, James L. Hanson, Kevin B. Kopp, Emma H. Yee
Civil and Environmental Engineering
Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extraction allows for beneficial use of the excess landfill heat as an alternative energy source. Two approaches are provided for the extraction strategy: extracting all of the excess heat above baseline equilibrium conditions in a landfill and extracting only a part of the excess heat above …
Waste Heat Generation: A Comprehensive Review, Nazli Yeşiller, James L. Hanson, Emma H. Yee
Waste Heat Generation: A Comprehensive Review, Nazli Yeşiller, James L. Hanson, Emma H. Yee
Civil and Environmental Engineering
A comprehensive review of heat generation in various types of wastes and of the thermal regime of waste containment facilities is provided in this paper. Municipal solid waste (MSW), MSW incineration ash, and mining wastes were included in the analysis. Spatial and temporal variations of waste temperatures, thermal gradients, thermal properties of wastes, average temperature differentials, and heat generation values are provided. Heat generation was influenced by climatic conditions, mean annual earth temperatures, waste temperatures at the time of placement, cover conditions, and inherent heat generation potential of the specific wastes. Time to onset of heat generation varied between months …
Measurement And Analysis Of Temperature And Pressure In High Altitude Air Shipments, Sher Paul Singh, Jay Singh, J. Stallings, Gary J. Burgess, K. Saha
Measurement And Analysis Of Temperature And Pressure In High Altitude Air Shipments, Sher Paul Singh, Jay Singh, J. Stallings, Gary J. Burgess, K. Saha
Industrial Technology and Packaging
This study was performed (at the request of the FAA) to measure temperature and pressure conditions observed by standard packages in the FedEx Next Day Air network and the environmental conditions of passenger aircrafts. To measure the single parcel environment, two destinations known to be served by non-pressurized feeder and pressurized aircrafts in the USA, San Luis Obispo, California, and Twin Falls, Idaho, were used to represent higher altitude paths. Test packages (0.30 × 0.30 × 0.30 m) containing one MadgeTech PRTemp110 recorder were shipped Priority Overnight by FedEx from East Lansing, Michigan. For 6 weeks, two test packages were …
Performance Comparison Of Thermal Insulated Packaging Boxes, Bags And Refrigerants For Single-Parcel Shipments, S. P. Singh, Gary J. Burgess, Jay Singh
Performance Comparison Of Thermal Insulated Packaging Boxes, Bags And Refrigerants For Single-Parcel Shipments, S. P. Singh, Gary J. Burgess, Jay Singh
Industrial Technology and Packaging
A range of packaging solutions exists for products that must be kept within a specific temperature range throughout the supply-and-distribution chain. This report summarizes the results of studies conducted over a span of 2 years by the Consortium for Distribution Packaging at Michigan State University. Thermal insulation packaging materials such as expanded polystyrene, polyurethane, corrugated fibreboard, ThermalCor® and other composite packaging such as thermal insulating bags were studied. Phase change materials such as gel packs were also evaluated. Properties such as R-value, melting point and heat absorption were examined and are reported.
