Deaerator Introduction. Mechanical and chemical deaeration is an integral part of modern boiler water protection and control. Deaeration, coupled with other aspects of external treatment, provides the best and highest quality feed water for boiler use. Simply speaking, the purposes of deaeration are:

Deaerators and Water Treatment | Halgo Power

Boiler feedpumps must overcome this high pressure as they pump treated conditioned feedwater from the deaerator to the boiler drum that will ultimately turn into steam. The size and capacity of boiler feedwater pumps are selected based on the steam output rating of the boiler as well as the operating pressure and temperature.

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.

Chapter 10 Boiler Feedwater Deaeration | SUEZ

Vacuum deaerators remove oxygen less efficiently than pressure units. A typical vacuum deaerator is shown in Figure 10-7. Important Considerations. Inlet water to the deaerators should be largely free from suspended solids, which can clog spray valves and ports of the inlet distributor and the deaerator trays.
