Draught is the pressure difference that causes a flow of air or gases from one point to another point in the boiler system.
Draught is required in a boiler system mainly due to two reasons.
To supply sufficient air for completing the combustion.
To remove flue gases from the system after combustion and the heat exchange.
There are two types of draught applied to the boiler system.
1.The natural draught.
2.The forced draught.
We will discuss here in this article about natural draught. The natural draught is always preferred since it does not need any running cost although it has a big initial cost. Natural draught allows the natural circulation of air through the boiler system. The natural draught mainly depends upon the height of the chimney.
