Precautions for the initial commissioning of a steam turbine
Thread Content
My workplace is about to carry out the initial testing of the turbine. I would like to ask everyone for some advice on the precautions to take during such testing. The turbine is manufactured by Shenyang Steam Turbine Group and it is equipped with a compressor. Thank you all!
First, conduct steam testing to ensure that the pipelines are in good condition and that the steam quality is satisfactory, in order to prevent impurities from reaching the turbine. The lubricating oil must also meet the required filtration standards (acid washing of the lubricating oil pipelines may be considered); the rest of the startup procedures should be followed as per the regulations.
I will mention several points: (1) All pressure gauges, temperature gauges, and transmitters have been installed； (2) Nitrogen at the normal pressure used to fill the accumulator with control oil pressure ； (3) Supply cooling water to the oil cooler ； (4) Fill the fuel tank with sufficient fuel, place the valves on the fuel system pipelines in the correct positions, and pay attention to the fuel temperature in the tank ； (5) Shut down or plug with blind flanges the units that do not meet the cycle requirements ； (6) Install a filter screen on the return oil pipeline to remove impurities ；
