A supercritical steam combined cycle system including a gas turbine; a supercritical steam turbine system including a supercritical section, a high pressure section, an intermediate pressure section and at least one low pressure section; and a supercritical steam heat recovery steam generator (HRSG) for receiving exhaust gas from the gas turbine for heating fluid from the steam turbine system. The HRSG includes a supercritical evaporator arranged to supply steam to a superheater between the supercritical evaporator and the inlet of the HRSG and a reheater receiving cold reheat steam from and returning reheated steam to the steam turbine system. The reheater includes a first section disposed downstream of and a second section disposed upstream of the supercritical evaporator along the exhaust gas flow path. Cool reheat steam from the steam turbine system is received by the first reheater section and steam leaving the first reheater section is supplied to the second reheater section upstream of the supercritical evaporator.

A boil-off gas treatment system is disclosed. The boil-off gas treatment system according to the present invention comprises: a compressor which compresses boil-off gas that is generated in an LNG storage tank of a ship or floating structure; a heat exchanger which cools the boil-off gas that has been compressed in the compressor using boil-off gas that is to be introduced into the compressor by means of exchanging heat therebetween; an expansion means which adiabatically expands the boil-off gas that was cooled in the heat exchanger; a gas-liquid separator which separates the boil-off gas that was adiabatically expanded in the expansion means into gas and liquid, and supplies liquefied natural gas to the LNG storage tank; and a bypass line which supplies the adiabatically-expanded boil-off gas from the downstream of the expansion means to the downstream of the gas-liquid separator.

The present invention relates to a nanobubble-and-hydroxyl-radical generator and, more particularly, to a system for processing polluted water without chemicals comprising: an air supply unit; an inlet pipe, connected to the air supply unit, for introducing a fluid; the nanobubble-and-hydroxyl-radical generator, comprising a pump connected to the inlet pipe, a drive motor connected to the pump, rotary blades connected to the drive shaft of the drive motor, and fixed blades connected to the inner wall of the pump and disposed between the rotary blades; and a discharge pipe, connected to the nanobubble-and-hydroxyl-radical generator, for discharging a nanobubble-generated fluid, wherein the circumferential surface of the rotary blades or the fixed blades, or both, is formed to be inclined inone direction. As such, the present invention provides a nanobubble-and-hydroxyl-radical generator capable of further enhancing a dissolution rate in such a manner that the circumferential surface ofeach blade is inclined to induce a disturbance phenomenon of air and a fluid, thereby accelerating micronization and mixing of air and a fluid.
