Steam flowrate to the deaerator (m_dot - body text.jpgs) has already been calculated at 334 kg/h. In this example the maximum water flowrate (the 'actual' capacity of the boiler) to the deaerator is 9 311 kg/h. Water valves are sized on volume flowrates, so it is necessary to convert the mass flow of 9 311 kg/h to volumetric flow in m3/ h.

The exergy efficiencies of individual components of the system such as the boiler, deaerator, and pre-heater were found to be 25.82%, 40.13%, and 2.617%, respectively, with the pre-heater having the lowest efficiency. Thus, the pre-heater has the highest potential to significantly improve the efficiency of the boiler system.

Both of these systems require a vent for removal of the released gasses. A good rule of thumb is that a deaerator should have a continuous 18 inch plume of escaping steam above the deaerator vent line. Monitoring a DA or feedwater heater's operating efficiency is easily accomplished using a spot check oxygen analysis kit.
