Boiler draught
Draught is the pressure difference which is necessary to draw the required quantity of air for combustion and to remove the flue gases out of the system. Thus the object of producing draught in a boiler is: (i) To provide sufficient quantity of air for combustion.
What is boiler Draught or draft?
The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.
The draught is necessary to force air through the fuel bed/ grate to aid in proper combustion of fuel and to remove the products of combustion i.e. flue gases to the atmosphere after they have given their heat to water being evaporated in the boiler.
What is the purpose of Draught?
What are the purpose of Draught? To supply required amount of air to the furnace for the combustion of fuel. The amount of fuel can be burnt per square foot of grate depends upon the quantity of air circulated through fuel bed. To remove the gaseous products of combustion.
What is called draught?
a current of unpleasantly cold air blowing through a room.
What is Draught and its classification?
Explanation: Draught is classified into artificial draught and natural draught. Natural draught is also known as chimney draught since it makes use of a chimney of sufficient height to create the required pressure difference. 3. Artificial draught is classified into steam jet and mechanical draught.
Draught is defined as the difference between absolute gas pressure at any point in a gas flow passage and the ambient (same elevation) atmospheric pressure. . Draught is achieved by small pressure difference which causes the flow of air or gas to take place. It is measured in milimetre (mm) or water

Lovely explanation sir🙏🙏
Bohot hi badhiya sir with practicle examolple
Thankyou So Much Sir...😄
One thing 😢not understand when you say making chimne bottom part high area and upeer part low area by which in bottom part area High pressure and upper part area low pressure by which steam flow high pressure to low pressure but when you applied physics formula pressure=fores/area chimni lower part low pressure because high area and chimni upper part High pressure because lower area .
Bernoulli's principle se
That rule is different

Area kam hone per to pr. Increase ho jata h na sir
Bhai area kam hone se pressure kam hota hai aur velocity jyada ho jata h
Sir cbse chapter dona
