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

This is the pressure measured from the datum of the atmospheric pressure. Although in reality the atmospheric pressure will depend upon the climate and the height above sea level, a generally accepted value of 1.013 25 bar a (1 atm) is often used. This is the average pressure exerted by the air of the earth's atmosphere at sea level. Gauge

The top of the furnace body is provided with an air outlet. 3.The horizontal coal-fired atmospheric hot water boiler adopts a three-return water-fire tube structure with a single drum longitudinally arranged. oil boiler oil gas organic heat carrier boiler organic heat-medium boiler
Atmospheric pressure hot water boiler, also called non-pressure hot water boiler, belongs to civil life boiler. The atmospheric pressure hot water boiler is a kind of non pressure hot water boiler with an air opening at the top, and the boiler body is always in the normal pressure running state. Its main characteristic is that the boiler is not pressurized and has no hidden danger of safety

However, steam at atmospheric pressure is of a limited practical use. This is because it cannot be conveyed under its own pressure along a steam pipe to the point of use. Note: Because of the pressure/volume relationship of steam, (volume is reduced as pressure is increased) it is usually generated in the boiler at a pressure of at least 7 bar g.
