Which is not accomplished in an underfired furnace ?
Correct answer: A. Increase in heating capacity/m2 of floor space
- A. Increase in heating capacity/m2 of floor space
- B. Elimination of cold spot at the bottom of the charge
- C. Reduction in the temperature of furnace gases
- D. Protection of the periphery of the charge from excessive radiation
Explanation
Underfiring is used to remove the cold region near the bottom, shield the charge edges from excessive radiation and lower the furnace-gas temperature. The stated increase in heating capacity per square metre of floor space is not normally an accomplishment of underfiring.
