Superheated Steam Boiler Feed Pump


Synthesis of Energy Systems: Methodology and Application

Superheated steam at 3 bar g with 10 °C of superheat (154 °C) is to be used as the primary heat source for a shell and tube process heat exchanger with a heating load of 250 kW, heating an oil based fluid from 80 °C to 120 °C (making the arithmetic mean secondary temperature (ΔT AM) 100 °C). Estimate the area of primary steam coil required.

Boiler and Feedwater Pump Efficiency Optimization

Pump Speed Control. Controlling pump speed is accomplished by variable-speed electric drives or by close-coupling a steam turbine to the pump. By definition, cogeneration power plants produce both electricity and excess steam where turbine exhaust is used as a heat source. A steam turbine driven feedwater pump is most often applied because of

Superheated Steam | Spirax Sarco

The Clayton Feedwater Pump is a pack-less and seal-less positive displacement type oil reservoir and diaphragm pump. It utilizes the diaphragm to isolate the feedwater in the pump column from the hydraulic oil in the crankcase. Water is drawn through the inlet check valves and discharged through the outlet check valves as the column of water is moved by the diaphragm.
