2011-6-2 · The pumps can provide feedwater to any of the High Pressure (HP) Feedwater Heaters, 1, 2, 6, 7 and 8. After the feedwater is heated in the HP heaters it is then sent through drum level control valves on the boilers 1, 2, 3, 6, and 7 from the drum level control valves to the Economizer inlet valves.
A ProSonix heater can be installed in boiler feedwater applications to heat up the returned condensate with low pressure steam from the turbine. These boilers often have feedwater heaters which are an integral part of the plant’s thermodynamic cycle. High Turndown on both steam and liquid allow for process flexibility and process
