In previous Modules, typical feedwater temperatures have been quoted at around 85 C, which is a practical maximum value for a vented boiler feedtank operating at atmospheric pressure. It is also known that water at 85°C contains around 3.5 grams of oxygen per 1 000 kg of water, and that it is the oxygen that causes the major damage in steam systems for two main reasons.
