Problems solved by technology

For many occasions that require high-temperature steam as heat transfer or other working medium, but the system working pressure is not high, it will bring certain difficulties, and have to use other expensive inert gases
[0003] In addition, the existing methods are difficult to adjust the pressure and temperature of the superheated steam generated by the steam generator, and it is difficult to control and adjust the steam pressure at a given superheated steam temperature, which brings inconvenience to the application in many occasions

Abstract

The invention relates to a steam generator capable of adjusting pressure and temperature. High-temperature steam can be generated under low pressure or specified pressure, the pressure and the temperature of the generated steam can be conveniently adjusted, and the demands for high-temperature steam under different working pressures are met.

Description

technical field [0001] The invention relates to a steam generator with adjustable pressure and temperature, which can generate high-temperature steam at a lower pressure or a specified pressure, and the pressure and temperature of the generated steam can be easily adjusted to meet the requirements of high-temperature steam under different working pressures. demand. Background technique [0002] Traditional steam generators or boiler systems have a steam drum where water is heated and vaporized to produce steam. This method of steam generation is limited by the three-phase equilibrium point of water, and requires very high pressure to generate high-temperature steam. For example, if water is heated to a supercritical state, the pressure will reach 22.3MPa, and the temperature can reach about 500°C. In general boilers, under a pressure of several kilograms, only 1-200 ℃ of steam can be produced. For many occasions where high temperature steam is required as heat transfer or ...
