K6050AP Hydrogen Purity and Purge Gas Analyser
Brand: MTL InstrumentsThe K6050AP analyser has been designed specifically for use in power stations.
Modern turbo-generators produce a great amount of heat and the most efficient way of removing this heat is by enveloping the parts in hydrogen, because hydrogen has seven times the cooling capacity of air.
It is possible for air to leak into the system, so it is essential to monitor the hydrogen purity for both efficiency and safety - as a hydrogen/air mixture will produce a potentially explosive atmosphere.
When maintenance needs to be carried out, the atmosphere inside the turbo-generator has to be replaced with air.
This cannot be a direct replacement because of the explosive mixture that would be produced in the process.
Instead, an inert gas, usually carbon dioxide, is used to purge the hydrogen, then air is introduced to purge the carbon dioxide.
The same procedure must be followed in reverse when replacing the hydrogen atmosphere.
