TEN (313310) Practical No: 06 Demonstration and working of Boiler Accessories Answer
Boiler accessories like economizers, air preheaters, and superheaters improve boiler systems' overall efficiency by recovering waste heat or optimizing fuel consumption. Students must learn how these accessories impact energy efficiency, environmental sustainability, and operational costs of industrial processes. Boiler accessories are components installed inside or outside the boiler to increase efficiency and proper operation. They are not necessary for boilers to function. However, energy conservation is an important aspect of any thermal engineering system. Accessories improve the performance of boilers or allied thermal systems.
TEN (313310) Practical No: 06 Procedure
1. Select boiler accessories available for demonstration.
2. Locate the selected accessories on the boiler model.
3. Observe the selected accessories thoroughly.
4. Write the function of the accessories in the given table.
5. List the parts and state the function of each part in the given table.
6. Explain the working of selected accessories.
Practical-related questions
1. Explain how an economizer works to improve the efficiency of a boiler system.
Answer:
2. List the typical applications where economizers are most effective in industrial settings.
Answer:
3. State the different types of superheaters used in boiler systems and their respective
advantages.
Answer:
4. Illustrate the use of de-superheater in super-heater.
Answer:
5. Explain the effect of the placement of a superheater within the boiler system on its efficiency and performance.
Answer:
6. State the purpose of an air preheater in a boiler system.
Answer:
The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas.
7. List the non-condensing type economizers.
Answer:
Plain Tube Economizers:
Bare Tube Economizers:
Cast Iron Economizers:
Finned Tube Economizers:
Conclusion
We completed TEN (313310) Practical No: 06 in which we learned and got information about the working of Boiler Accessories.
