Rate of heat release in a furnace, which is the measure of heat intensity, is defined as_________________?
Correct answer: C. kcal/hr/m3 combustion space
- A. kcal/hr
- B. kcal/m3 combustion space
- C. kcal/hr/m3 combustion space
- D. None of these
Explanation
Heat-release rate measures furnace heat intensity as the heat released per unit combustion-space volume per unit time. Its units are therefore kcal/(hr·m³), not merely kcal/m³ or total kcal/hr.
