AI Technical Summary

Technical Problem

Conventional superheated steam generators face issues with pressure fluctuations that can lead to damage when the load loss in the steam channel increases, as the discharge pressure rises uncontrollably, potentially causing harm to the steam generation units.

Method used

A superheated steam generator with a safety device that includes pressure and temperature sensors, a safety circuit, and a releasing unit to prevent damage by controlling steam generation based on detected pressures and temperatures, ensuring the amount of steam generated remains stable within a ±1% variation.

Benefits of technology

The safety device effectively prevents damage to the steam generation units by releasing steam or limiting power supply when pressure or temperature thresholds are exceeded, maintaining steam generation stability and safety.

Abstract

A superheated steam generator in which the amount of generated steam is controlled by the amount of electric power includes: a steam generation unit that generates steam from water by inductively heating a first conductor pipe having a spiral shape; a superheated steam generation unit that generates superheated steam by inductively heating a second conductor pipe having a spiral shape; a control unit that controls an amount of steam to be generated by the steam generation unit based on an amount of electric power to be supplied to the steam generation unit; and a safety device that prevents damage to the steam generation unit or the superheated steam generation unit based on a water pressure in the steam generation unit, a pressure or a temperature of the steam in the steam generation unit, or a pressure or a temperature of the superheated steam in the superheated steam generation unit.
