The corrective action taken was to take the Boiler off line. Force cool the boiler, purge the water from...

The off spec condition occured due to marginal transient deviation in chloride contamination in a high pressure boilers feeding to a back pressure turbine. The low pressure steam is utlised for MSF desalination.The steam condenser leaked which resulted in slight chloride contamination up...
thanks metenger, for the info on method of testing, ok this is the detail for life assessment exercise. In case of transient phase off spec operation in water quality should the opertor go for tube ispection & testing case is a new boiler, off spec of water chemistry 12 hrs and water quality...
Can somebody volunteer information on the best practices that should be adopted for the testing of High Pressure high temprature Steam boiler ( ca 170 bar 515 C )tubes for scale accumulation & tube thickness verification.
