Pressurised Deaerators | Spirax Sarco

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.
