Thermal efficiency of blast furnace stoves used for heating blast (air) may be about _____________ percent?
Correct answer: D. 80
- A. 20
- B. 40
- C. 60
- D. 80
Explanation
Blast-furnace stoves are regenerative heat exchangers and commonly achieve thermal efficiencies of about 80%. They store heat in checker brickwork and transfer it to the incoming blast air.
