Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept A regenerator is a heat exchanger used to preheat incoming fuel or air using waste heat from exhaust gases.
Step 2: Meaning This system is essential for furnaces that require very high temperatures but use fuels with relatively low calorific value.
Step 3: Analysis LD converters and electric furnaces do not typically use external regenerators for air preheating. The Open Hearth furnace relies on Siemens' regenerative principle to achieve the temperatures needed for steelmaking.
Step 4: Conclusion Thus, the open hearth furnace is the standard industrial example that employs a regenerator system. Final Answer: (B)
