No-load single test of turbine

It’s necessary to do this during construction; usually, the manufacturer’s debugging engineers are present, and they bear the associated risks. It’s sufficient for the owner to be present as a witness You need to pay attention to learning things like quick-close valves, the tuning of steam valves, the tuning of interlocks, and the procedures for starting up the system. The risk is that the speed control valve or interlocks are not properly adjusted. It’s due to overspeed or damaged bearing shells; generally, it’s necessary to carry out alignment work before starting up, as well as static testing of the turning gear and various interlocks. As long as an emergency stop function is available, there are usually no problems. Compared to load testing, the biggest issue with the turbine is an increased steam consumption, and the exhaust temperature is higher than when it is under load~~

I took a look at your profile picture; it seems like you’re a maintenance engineer? In that case, there should be no major issues regarding meeting the data and requirements for the initial installation from a mechanical standpoint. Also, it’s important to check whether any changes were made to the speed control system; if so, it’s still recommended to have the manufacturer’s technicians come and make the adjustments

Thank you very much. After the turbine is overhauled, I want to conduct a single-unit test; I’m worried about potential problems. Starting it in conjunction with other systems also raises concerns, as there’s a risk that issues with the turbine could affect the progress of system startup. The control system didn’t move; it was only the turbine that was under maintenance
