Pre-commissioning involves developing processes and setting up the documentation that guides the commissioning team through the entire commissioning process. It includes the following components: (2)

1.) Ensure that the quality and temperature of the water to be used for the testing are within the approved parameters 2.) Ensure that all boiler connections are properly blinded off using rated spectacle blinds for all lines. Since this is a new installation, the hydrostatic test should be done BEFORE the safety valves are installed. - If the PSVs are already installed, then they need to be blanked, plugged, or gagged during the hydrostatic test. 3.) Ensure that all instrumentation connects are blanked except the temporary temperature and pressure devices specifically calibrated and tested for monitoring and recording/documenting the hydrostatic test 4.) Flush to clean out all fill and feedwater lines before the boiler is filled 5.) Use demineralized water to fill the boiler and ensure that a compatible corrosion inhibitor is added to mitigate the potential for corrosion. 6.) Superheaters are normally designed with temporary connections so that they can be flushed backwards into the boiler to remove any fabrication and construction contaminants. 7.) Fill the boiler through the economizer with the steam drums doors open. When the drum begins filling, allow the water to fill the downcomers and then the waterfalls of the boiler. Periodically, blowdown all the water wall headers as the boiler fills and open the mud drum blowdowns and clean all the lines out as many times as necessary to prove the lines are blowing clear. Continue to monitor the water level in the steam drum until the water walls are full and water begins to return to the drum. Check the water in the drum for any contaminants or construction materials. Once the water is clean, all the wall tubes are full, and the water level reaches the drum door openings, stop the feed pump and install the doors. 8.) Continue to fill the boiler with the steam drum and superheater vents fully open until water begins to flow out of the boiler drum vents 9.) Close the steam drum vents and fill the superheaters with water until the water begins to flow out the superheater vents. Shut off the feedwater pump and close the superheater vents. 10.) Using the feedwater or fill pump, slowly raise the pressure within the pressure parts to the MAWP of the boiler. Fix leaks during this time. 11.) Once all the leaks have been repaired, the pressure on the boiler is raised slowly until it reaches 1.5 times the MAWP. - The pressure must be held for a minimum of 30 minutes and make sure the pressure doesn't decrease by 10%.
