Utilization of Navy-Generated Waste Oils as Boiler Fuel-Economic Analysis and Laboratory Tests.

Abstract : Feasibility of utilizing Navy-generated waste oil is reported. Estimates show that between 5% and 13% of the Navy boiler requirements(excluding coal) may be met by utilizing waste oils. Based on the FY-77 Navywide average cost for fuel oils, fully utilizing the waste oils results in $9-23M annual fuel bill reduction for the Navy. Laboratory tests were conducted, and the results show that the Navy waste oils are substantially the same as regular fuel oils in boiler firing (providing the waste oils are reasonably free of water and solid contaminants). Only minor burner adjustments are sometimes necessary in order to achieve efficient combustion. Long-term tests in in-service boilers are recommended for development of guidelines for utilizing waste oils as boiler fuels. (Author)
