suijitupian96.jpg" />Noncondensable gases and some steam are released through the vent. Steam provided to the deaerator provides physical stripping action and heats the mixture of returned condensate and boiler feedwater makeup to saturation temperature. Most of the steam
suijitupian4.jpg" />2/1/2011 · When the steam boiler is not in a heating cycle, the radiator air vent is open, allowing ambient air to fill the radiator. As a heating cycle begins, steam flows up through the supply pipe to the radiator. As the radiator fills with steam, it pushes the air out through the open vent. This replacement of cool air with hot steam heats up the vent
