ABSTRACT

We have designed power cogeneration system from the liquefied natural gas (LNG), as a fuel. The cogeneration system combines the gas turbine system and self-designed thermoacoustic engine. The system applies LNG which removes the harmful emissions including nitrogen oxide, sulfur oxide, particulate matters, etc. and reduce the CO2 emission in comparison of the traditional long-carbon-chain fossil fuels. Although LNG is convenient for transporting and storing, it should be regasified before applied in a gas turbine for electric power generation. We have explored to reuse the cold energy source from LNG at the cryogenic level and waste heat from gas turbine for the second power generation for improving the overall thermal efficiency of the system. The thermoacoustic engine, having a high efficiency with a low maintaining cost, has been applied. The talk covers the application review of LNG, the design of thermoacoustic engine in the kilowatt level, regasification of LNG, phase change storage, overall system test. The thermal, economic, environmental, and sustainability models has been developed for the LNG powered cogeneration system. We are extending the models in the present project on the ammonia-based gas turbine system for the low carbon emission.
