Abstract: The present disclosure relates to a gas turbine plant which decomposes ammonia into a decomposition gas including hydrogen and supplies the decomposition gas as fuel to a combustor of the gas turbine. The gas turbine plant supplies sufficient heat to the ammonia in order to thermally decompose the ammonia effectively and separates the residual ammonia present in the decomposition gas and supplies the decomposition gas to a combustor of the gas turbine.

Abstract: An ultra-efficient turbo-compression cooling system links an organic Rankine power cycle and a vapor compression cooling cycle using a turbine and compressor that shares a single shaft and further linked to an evaporative condenser. The power cycle implements a waste heat exchanger configured to evaporate a working fluid and a turbine configured to receive the evaporated working fluid. The turbine has a plurality of vanes disposed around a central shaft and configured to rotate as the working fluid expands to a lower pressure within the turbine. An evaporative condenser then condenses the working fluid to a saturated liquid and a mechanical pump pumps the saturated liquid to reenter the waste heat waste heat exchanger. The cooling cycle implements a compressor configured to increase the pressure of the working fluid, with the evaporative condenser (shared with the power cycle) configured to condense the working fluid to a saturated liquid upon exiting the compressor, an expansion valve wherein the working fluid expands to a lower pressure, and an evaporator rejecting heat from a circulating fluid to the working fluid, thereby cooling the circulating fluid.

Abstract: Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

Abstract: A system includes a retention system configured to support a heat exchanger along a flow path within a duct. The retention system includes a first sleeve configured to extend between opposite first and second walls of the duct, a first cable extending through the first sleeve, and a first bumper coupled to the first sleeve. The first bumper is configured to contact the heat exchanger. The retention system includes a first tensioner coupled to the first cable, wherein the first tensioner is configured to provide a first tension in the first cable. The first tension is adjustable to detune the natural frequency of the heat exchanger away from any excitation load frequencies caused by an exhaust gas flow through the duct.
