Draught means a force required toa)maintain a flow of air through the ...
The correct answer is option 'D' - all of the above. Let's break down each option and explain why it is correct:
a) Maintain a flow of air through the fuel bed and aid in the proper combustion of fuel:
Draught, in the context of combustion systems, refers to the flow of air or gases through the system. To ensure proper combustion of fuel, a continuous supply of air is required. The draught force helps maintain this flow of air through the fuel bed, providing oxygen for the combustion process. Without adequate draught, the combustion process may not be efficient, leading to incomplete combustion and the production of pollutants.
b) Draw the resulting hot gases through the system:
After the combustion process, hot gases are generated. These gases need to be efficiently removed from the system to prevent any buildup or backflow. The draught force plays a crucial role in drawing these hot gases through the system, ensuring proper ventilation and preventing the accumulation of harmful gases.
c) Force the spent flue gases towards the chimney and then to the atmosphere:
Once the hot gases have been drawn through the system, the draught force is responsible for forcing these spent flue gases towards the chimney and then to the atmosphere. The chimney creates a natural stack effect, where the hot gases rise and are expelled from the system. The draught force aids in this process, ensuring the proper flow of gases and preventing any reverse flow.
In summary, draught in a combustion system is essential for maintaining a flow of air through the fuel bed, aiding in the proper combustion of fuel, drawing the resulting hot gases through the system, and forcing the spent flue gases towards the chimney and then to the atmosphere. All three options (a, b, and c) are necessary for the efficient operation of a combustion system, and hence, the correct answer is option 'D' - all of the above.
