A method and a device for generating superheated steam from a working medium, which includes the following steps: feeding of a working medium in the liquid phase to a specific heating tube and temperature regulation of the specific heating tube. Furthermore, the specific heating tube is temperature-regulated with a defined amount of thermal energy, as a result of which superheated steam is formed in the specific heating tube from the working medium fed in the liquid phase, the superheated steam then departing from the specific heating tube.

The present invention is intended to prevent lifetime degradation of a conductor tube by reducing heat deterioration at output ports of the conductor tube. A superheated steam generator generates superheated steam by heating steam flowing through a spirally wound cylindrical conductor tube. The conductor tube is axially short-circuited and subjected to induction heating by a magnetic flux generation mechanism disposed on one or both of inner and outer sides of the conductor tube. Output ports of the conductor tube are disposed at axial midportions of the conductor tube.

A steam generator for generating a superheated fluid from a working fluid using a stream of heated gas, the steam generator comprising: a housing, which defines a gas flow path having an inlet at one, upstream end thereof into which a stream of heated gas is delivered and an outlet at the other, downstream end thereof; and a steam generation module which is disposed within the gas flow path of the housing, the steam generation module comprising a heat exchanger which receives a working fluid and is operative to raise the temperature of the working fluid to provide a saturated fluid, and a superheater which receives the saturated fluid from the heat exchanger and is operative to raise the temperature of the saturated fluid and provide a supersaturated fluid.

An evaporator with integrated heat recovery incorporates a vapor tube in a combustion chamber surrounded by a water jacket. The water jacket is in fluid communication with an exhaust gas heat exchanger. Coolant circulates through the exhaust gas heat exchanger to recover heat from exhaust gasses leaving the combustion chamber and then circulates through the water jacket surrounding the combustion chamber to recover heat not delivered to the operating fluid. The evaporator may incorporate a condenser within the housing and in fluid communication with the exhaust gas heat exchanger and water jacket. Coolant may enter the evaporator housing at the condenser before circulating through the exhaust gas heat exchanger and water jacket.
