Water Vapor Generation Device

The water vapor generation device is an auxiliary experimental device connected to simultaneous thermal analyzers (comprehensive thermal analyzers) and thermogravimetric analyzers. It is mainly used in auxiliary experiments for energy and thermal decomposition of coal, chemical, and metal materials, enabling full experimental analysis of samples in a water vapor atmosphere. It features precise quantification of water vapor, fast heating and vaporization rates, and excellent thermal insulation and constant temperature performance.

The overall composition of the device is as follows: The "intelligent water vapor control integrated machine" controls the temperature range and constant temperature duration of each station. A plunger pump outputs a fixed amount of liquid, which is vaporized in the water vaporization chamber. A steady-flow tank maintains a stable vaporization state at a constant temperature. The vapor is carried by an inert gas through a constant-temperature gas conveyor belt and a constant-temperature connector, then enters the reaction chamber of the instrument. The entire gas path is directed past the sample position and finally discharged through the exhaust port.
