steam flow in boiler at thermal plant -

2.3. Calculation of the Boiler Feed-Water Pump Turbine . When the main steam pressure and flow rate change, the output of Boiler Feed-Water Pump Turbine (BFPT) will change too. Therefore, the influence of BFPT on the thermal efficiency cannot be ignored. From the outlet of feed-water pump to the main steam valve, the phase of working fluid changed.

Steam Flow Rate - an overview | ScienceDirect Topics

The temperature difference between the primary and secondary fluid at the OTSG outlet is similar to that at the outlet of the cold-leg of a recirculating steam generator (Green and Hetsroni, 1995). When the outlet steam pressure decreases, the feedwater flow rate increases proportional to the increased steam flow rate. At lower power levels
