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.Get Price
They can be of vacuum or pressure type. The vacuum type of de-aerator operates below atmospheric pressure, at about 82oC, can reduce the oxygen content in water to less than 0.02 mg/litre. Vacuum pumps or steam ejectors are required to maintain the vacuum. The pressure-type de-aerators operates by allowing steam into theGet Price
conjunction with the traditional vacuum deaerator will allow the lowest possible levels of dissolved gasses to the boiler.
