Apparatus for raising the temperature of superheated steam and ultra-high temperature steam generator

An apparatus for raising the temperature of superheated steam comprising:

• an inlet into which superheated steam is introduced;
• a body to raise the temperature of the superheated steam heated by an external heat source;
• and
• an outlet provided inside the body and discharging the superheated steam temperature-raised by the body to the outside,
• wherein an inner surface of a sidewall of the body is formed with an inner protrusion for heating the superheated steam while rotating the superheated steam along the inner surface of the sidewall,
• wherein an end of the inner protrusion has a shape bent upward in parallel with the inner surface of the sidewall of the body.

An apparatus for raising the temperature of superheated steam comprising:

• an inlet into which superheated steam is introduced;
• a body to raise the temperature of the superheated steam heated by an external heat source;
• an outlet provided inside the body and discharging the superheated steam temperature-raised by the body to the outside;
• and
• a steam pipe forming a flow path through which the superheated steam flows and connected to the inlet,
• wherein the steam pipe is formed on an outer surface of the body, forms a flow path through which the superheated steam flows in a meandering shape along a horizontal direction with respect to an outer circumferential surface of the body, and surrounds the outer circumferential surface of the body.

A temperature steam generator equipped with a coil type superheater comprising:

• a superheater comprising an inlet port connected to an exit side of a boiler for introducing steam discharged from an exit of the boiler, an outlet port for discharge steam introduced through the inlet port, a temperature-raising pipe for interconnecting the inlet port and the outlet port and forming a coil-shaped flow path for raising the temperature of the steam introduced through the inlet port, a cylindrical first inner wall having an outer circumferential surface of a first diameter facing an inner circumferential surface of the temperature-raising pipe forming the coil-shaped flow path, or a cylindrical second inner wall having an outer circumferential surface of a second diameter smaller than the first diameter facing the inner circumferential surface of the temperature-raising pipe, and a cylindrical outer wall having an inner circumferential surface of a third diameter larger than the first diameter facing an outer circumferential surface of the temperature-raising pipe;
• and
• a furnace having a space into which the superheater is built, the furnace comprising a gas inlet port into which combustion gas is introduced, and a gas outlet port through which the combustion gas is discharged, the combustion gas introducing from the gas inlet port and transferring convection heat to the superheater.
