A laboratory evaluation of a shipboard Phase II multifunctional waste incinerator (MFI), consisting of testing the unit for a minimum of 1200 operational hr to characterize performance, reliability, maintainability, habitability, and safety, demonstrated that the solid waste processing requirements are acceptable for various wastes with a 98-percent average reduction efficiency on a weight basis. Additionally, freshwater sewage and waste oil can be processed on demand at the required flow rates. All wastes can be processed with an average operator attention time of less than 5 min/hr. Recommendations for certain deficiencies include provisions for extra insulation and safety guards, development of an adequate technical manual, and optimization of feed and fuel processing systems. Upon completion of the recommended modifications, further testing, including a vibration evaluation, will complete the requirements prior to installation of the MFI on board a naval vessel for shipboard evaluations and approval for service use.

This report describes vibrational testing and identifies recommended changes to a multifunctional waste incinerator (MFI) intended for use on seagoing vessels as an alternative for overboard discharge of potentially harmful waste. The testing reported completes the third part of Phase II testing, laboratory evaluation of a land-based system. Vibrational testing was completed on both 0 degs. and 90 degs. transverse axes in addition to the vertical axis. The modified MFI operated as required and withstood the vibrational testing environment. Modifications, especially in the use of aluminachromic oxide plastic refractory in the sewage chamber, proved satisfactory. Some design changes are recommended for easier disassembly and greater structural integrity. (Author).
