In a combustion process, draft refers to the flow of air or gases associated with the combustion reaction, which is created by pressure differences. This flow is essential for the efficient functioning of the combustion system, as it facilitates the movement of fresh air into the combustion chamber, where it mixes with fuel, and enables the expulsion of combustion by-products, primarily exhaust gases.

Proper draft is crucial because it influences combustion efficiency and the overall performance of the boiler or furnace. If the draft is insufficient, it can lead to incomplete combustion, which may produce excess carbon monoxide or other harmful emissions. Conversely, excessive draft can cause rapid expulsion of heat and gases, which can also be detrimental to efficiency.

Understanding draft is vital for operating and maintaining steam engines and boilers correctly, as it directly impacts the combustion process's effectiveness and safety measures that must be followed.
