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.

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.
