Turbine power issue
Thread Content
Great god of Haichuan, I have a question I’d like to ask. According to the turbine power-flow curve, with a constant amount of air intake, the more exhaust gas is removed, the lower the output power becomes. Could you explain the issue of power changes during the distribution and regulation of work between the high-pressure cylinder and the low-pressure cylinder? Thank you
Based on the steam balance design of the plant, the steam flow and power distribution between the high-pressure and low-pressure turbines are determined under rated operating conditions. When more steam is extracted for regulation, the steam flow to the low-pressure turbine decreases, resulting in a lower output power from that turbine; as a result, more steam needs to enter the high-pressure turbine to generate the necessary power to meet the demands of the load. The opposite.
Thank you. We use a vacuum condensing turbine; could you share any data on power calculation?
