Device for generating saturated steam with controllable steam pressure

Abstract

The invention discloses a device for generating saturated steam with controllable steam pressure, belonging to the field of experimental equipment. The device comprises a steam pre-generating device and a steam saturation generating device, wherein the steam pre-generating device is composed of a three-neck flask (1) and an aluminum heating sleeve (2); and the steam saturation generating device is composed of a glass ball (5), a constant-temperature water bath kettle (6), a constant-temperature water bath tube (7) and a siphon tube (8). A quartz tube (4) is connected with the steam pre-generating device, a steam saturation generating device and a reaction furnace; and silicon rubber electric heating wires (3) are densely wound outside the quartz tube (4). According to the invention, the steam pressure is controlled by controlling the temperature of the water bath kettle, the saturated steam with controllable steam content and pressure can be generated, and the actual high-temperature water containing environment can be simulated in a laboratory. The device has a simple structure, is easy to be connected with the existing equipment and convenient to replace, and provides a simple and fast way for researchers.

Description

technical field [0001] The invention belongs to the field of experimental equipment, relates to a saturated water vapor generator with controllable water vapor pressure, and in particular provides a water vapor generator capable of controlling water vapor content and pressure that meets laboratory requirements. Background technique [0002] In high-temperature fields such as aerospace and metallurgy, non-oxide materials have attracted more and more attention because of their excellent high-temperature resistance and corrosion resistance. However, in practical applications, the use environment of materials is mostly high-temperature corrosion. It is a common corrosive environment. For example, SiC-based composites, which are important components of gas turbines, are often exposed to high-temperature environments, while fuel combustion generates a large amount of water vapor. In the field of metallurgy, due to hydrogen (H 2 ) reduction ability is 14 times that of CO, and it ...

AI Technical Summary

Problems solved by technology

Under high temperature and water-containing conditions, the protective oxide film of non-oxide materials reacts with water to cause the oxide layer to fall off, resulting in the loss of the original properties of the material

[0003] At present, there are few studies on the performance of materials under high temperature and water content conditions, because there is no water vapor generating device that can provide water vapor content and pressure control
