Diesel-generating plant waste heat recovery systems at remote locations

Abstract At remote locations typical of mines and associated ore processing plants, diesel electric generators are ideally suited for power plants due to their inherent operating flexibility, efficiency and reliability. In recent years rapid escalation in fuel and related transportation costs has made extensive waste heat recovery from generating sets financially attractive to a much greater extent than previously.
The paper outlines key considerations during planning and design stages for utilizing the various waste heat sources available to best advantage. Based on two 1980 mining projects built in the Canadian Arctic, data is presented on potential operating and capital costs savings. A review of heat balances, engineering flow diagrams and major equipment selections for process and building heating systems utilizing waste heat is included.
Keywords: Engineering, Design, Diesel-generating plants, Waste heat recovery systems. Project design, Energy, Polaris project, Lupin project.

Summary: This paper presents a preliminary assessment of the technical and economic feasibility of a caustic leach - electrowinning process for the recovery of zinc and lead from electric arc furnace baghouse dust at a mini-steelplant.
Recent studies and literature are referenced briefly as they pertain to the formation and characterization of dust, toxicity considerations and alternative dust treatment and disposal options.

Summary: The highly specialized communication systems used in the mining industry place exacting demands on equipment and transmission media. Safety and reliability of services are perhaps the two most important factors. Fibre optics is ideally suited to meet these stringent requirements. Aside from being an intrinsically safe, non-sparking and EMI/RFI immune medium, fibre optics offers greater reliability, higher quality of services and superior flexibility over conventional copper or radio-based...

Summary: Dust size distribution and aerosol size distribution measurements have been carried out in several Canadian underground uranium mines. In addition, dust samples have been analyzed for long-lived radioactive products of the U-238 and Th-232 natural decay chains using α-spectroscopy and γ-spectroscopy techniques.
From the data collected one may summarize: (a) most airborne particulates are of size below 1 µm and 50% by mass are found above 1 µm; (b) dust clouds are...

Summary: Canada, with one of the largest continental shelf areas in the world, has done little to evaluate its offshore unconsolidated mineral resources which include heavy minerals (gold, chromite, rutile etc.) and industrial minerals (silica sand and aggregates). During glaciation much of the continental shelf was covered with an ice sheet and later subaerially exposed with the result that glacial, glaciomarine and fluvial processes deposited sediments that may contain heavy minerals derived from...
