Draft steam issues in extraction steam turbines
Thread Content
Dear experts, does anyone know at what point in operation a extraction steam condensing turbine should have its extraction steam activated – after it has reached full load or during the process of loading up? Also, what percentage of the steam consumption at full condensing capacity does it account for when full condensation occurs?
After the pure condensation mode is operating normally, steam extraction is initiated; as for the proportion of full condensation mode in the total load, it depends on the design values
