The most effective way to eliminate the large amount of heat generated by modern turbine generators during operation is to encapsulate the components that need to be cooled in hydrogen gas (H2), as the cooling efficiency of hydrogen gas (H2) is seven times that of air. However, due to the possibility of air infiltration into the system, it is necessary to monitor the purity of hydrogen (H2) to ensure high efficiency and safety of the equipment. When maintenance is required, the turbine generator must be replaced with air. Due to the generation of explosive mixtures, it is not possible to directly replace hydrogen (H2) with air. Therefore, we use an inert gas (usually carbon dioxide CO2) to extrude hydrogen gas (H2), and then introduce air to remove carbon dioxide (CO2). When hydrogen gas (H2) needs to be re injected, reverse the program.
The HA1600 analyzer is designed specifically for power plants and provides three range options to monitor hydrogen (H2) purity and start stop during the generator blowdown phase. Single thermal conductivity sensor using mature HAXTEC technology, calibrated for three range stages. The inherent stability of the system can reduce calibration frequency and lower usage costs.
According to different process conditions, different sample gas pretreatment systems (standard or customized) can also be selected for HA1600. By integrating filters, pumps, and regulators, provide sample gases that meet the requirements. Oil mist, water vapor, pressure calibration, and sending the sample gas back to the system can all be achieved. HAXTEC engineers will recommend a suitable system for you after obtaining the complete airflow content specifications. When the analyzer needs to be used in hazardous areas, electrical devices can be installed in Exd explosion-proof enclosures.
