POSSIBLE USES OF THERMOACOUSTIC HEAT MACHINES IN THE SHIP POWER PLANTS
Abstract
The article deals with changes in the structure of waste energy flows of modern SPP that are associated with the use of modern highly efficient engines and LNG fuels. It is shown that reducing the temperature levels of available waste heat resources, and the appearance of cryogenic working fluids require the introduction of new technical solutions. Thermoacoustic technologies can be used in SPP for disposing low temperature waste heat resources. Thermoacoustic basic theoretical model shows that there is a fundamental opportunity for thermoacoustic machines to work using low-temperature sources of energy relief. A universal scheme of thermal recycling of waste energy SPP with an intermediate high-temperature coolant was also offered. A schematic diagram of the power generating system for cryogenic fuel regasification by thermoacoustic technology adjusting to SPP with LNG fuels was developed. The technical solutions proposed in the paper can be used in present-day SPP to improve their overall performance. Thermoacoustic technology can potentially provide opportunities for improving SPP and developing new innovative systems.
