Abstract : The goal of this project is the development of a novel, actively controlled, shipboard sludge incinerator using state of the art pulsating combustion technology. This study is aimed at determining the feasibility of such an incinerator, developing the technology to construct a suitable pulse combustor for exciting high amplitude velocity oscillations in the incinerator, and examining the benefits obtained from this technology. Two approaches have been taken towards the development of a suitable pulse combustor. First is the development of a tunable pulse combustor that can force resonant oscillations in the incinerator chamber. The second approach is to develop a high amplitude, low frequency pulse combustor that can generate bulk mode type pulsating flow in the incinerator chamber. Two tunable pulse combustors have been developed for testing; one is mechanically tuned, the other is a novel, electronically tuned pulse combustor designed be used in conjunction with a previously developed fuel modulation system. While both systems show some promise for use in the sludge incinerator, they currently have shortcomings, such as their inability to operate on liquid fuels. A single frequency, aerodynamically valved, oil burning pulse combustor was also constructed. While this burner burns liquid fuel and produces high amplitude pulsations, it is not tunable, and therefore, oscillations forced in the incinerator are not resonant. Improvement and testing of these systems will be continued under this project.
