Abstract: A vertical type once-through heat recovery steam generator (HRSG) capable of improving operational stability during rapid startup and lifetime of a steam turbine while reducing environmental pollution caused by emissions, and a combined power generation system including the HRSG are provided. The HRSG includes a medium-pressure section including a medium-pressure side desuperheater installed at the rear of a medium-pressure superheater to lower the temperature of the steam supplied to a medium-pressure steam turbine, and a high-pressure section including a high-pressure side desuperheater installed at the rear of a high-pressure superheater to lower the temperature of the steam supplied to a high-pressure steam turbine.

Abstract: The present disclosure relates to a gas turbine plant which decomposes ammonia and supplies it 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 it to a combustor of the gas turbine.

Abstract: A printed circuit-type heat exchanger includes a vaporizer having a structure in which one or more A-channel plates and one or more B-channel plates are sequentially stacked, to vaporize a fluid A with heat exchange through the A-fluid channels. A gas-liquid separator separates the fluid A into a vaporized gas and a non-vaporized liquid and includes a gas outlet for the vaporized gas and a liquid outlet for non-vaporized liquid. A super heater, having the same structure as the vaporizer, super heats the vaporized gas with heat exchange through the A-fluid channels and discharges the superheated gas through a gas outlet communicating with the outside. A first intermediate plate is disposed between the vaporizer and the gas-liquid separator to separate the vaporizer from the gas-liquid separator, and a second intermediate plate is disposed between the gas-liquid separator and the super heater to separate the super heater from the gas-liquid separator.

Abstract: A heat exchanger includes a stack of channel plates including first and second channel plates alternately stacked on one another such that fluids A and B are heat-exchanged each other. The first channel plate has a fluid path for fluid A on one surface thereof, wherein inflow and outflow parts for fluid A are formed on the fluid path for fluid A, and the second channel plate has a fluid path for fluid B intersecting with the fluid path for fluid A on one surface thereof. The first channel plate has communicating structures corresponding to the inflow and outflow parts for fluid B. The heat exchanger also includes an upper plate section attached to an upper surface of the stack, and a lower plate section attached to an undersurface of the stack.
