HITECH INSTRUMENTS A member of the MTL Instruments Group technical datasheet K6050AP hydrogen purity and purge gas analyser Designed for hydrogen cooled turbines in power stations Proven sensor technology Measures all gas purge stages Weatherproof to IP65 Reliable, simple to use Data logger output Ideal backup for fixed analysers Applications Hydrogen cooled synchronous compensators Analysers available for CO2 or N2 purging katharometer sensor, based on Hitech’s proven thermal conductivity technology, is calibrated over the three ranges. The inherent stability of this system means infrequent calibration and a low cost of ownership. There are no consumables and no spares are required for the first two years of operation. The K6050AP analyser has three ranges to monitor the hydrogen purity and the two stage gas-purge cycles. A single Hydrogen cooled turbo-generators The 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. All your turbine gas analysis requirements in one package from the katharometer experts. 500-0002 Rev2 310311 www.hitech-inst.co.uk hitechsales@cooperindustries.com The K6050AP portable analyser is a complete instrument in a rugged case. It is the portable equivalent of our fixed version K1650AP analyser, having rechargeable batteries (supplied) capable of lasting for a full purge cycle. A sample pump, 0 to 1V recording output, a flowmeter and needle valve are all included as standard. Sample conditioning filters are available, if required, to remove potential oil mist and water vapour from the sample prior to analysis. For sites using nitrogen as the purge gas (instead of CO2) please contact Hitech for an alternative solution.
