Application scenarios, necessity, monitoring points, technical parameters, selection requirements, and application value of online hydrogen analysis instruments in power plant production and operation. In the production process of thermal power plants, gas-fired power plants, and new energy supporting power plants, hydrogen is a key process gas:

1. The stator and rotor of the generator set are cooled by hydrogen gas, and the machine is filled with high-purity hydrogen gas for heat dissipation and insulation;

2. The boiler hydrogen production station and electrolytic hydrogen production unit continuously produce hydrogen gas for cooling and backup of the generator;

3. At the same time, if the purity of hydrogen does not meet the standard, it will lead to a decrease in generator insulation, increased losses, reduced unit efficiency, and shortened equipment service life.

Therefore, it is necessary to monitor hydrogen purity, humidity, leakage concentration, and mixture composition in real-time 24 hours a day, and equip professional online hydrogen analysis instruments.

1. Online monitoring of hydrogen purity inside the generator

2. Gas analysis for electrolytic hydrogen production in hydrogen production stations

3. Hydrogen leakage monitoring in power plant workshops and computer rooms

4. Auxiliary analysis of hydrogen components in boiler and flue gas system
