In regenerative air preheater (as practised in heating of coke ovens), the heat is transferred_________________?
Correct answer: E. By heating an intermediate material (like chequor bricks) and then heating the air from this
- A. Through a metallic wall
- B. By direct contact of hot flue gas with air
- C. None of these
- D. hot material
- E. By heating an intermediate material (like chequor bricks) and then heating the air from this
Explanation
A regenerative air preheater first stores heat in a solid intermediate material such as chequer bricks. The incoming air then receives heat from the warmed bricks rather than through a continuously separating metallic wall.
