Pitch creosote mixture (PCM) as compared to furnace oil is a better fuel, because its ___________________?
Correct answer: A. All A., B. and C.
- A. All A., B. and C.
- B. Sulphur content is lower
- C. Flue gas has lower dew point thereby facilitating more waste heat recovery
- D. Emissivity factor is higher
Explanation
PCM generally has higher flame emissivity, lower sulphur content, and produces flue gas with a lower acid dew point than furnace oil. The lower dew point permits greater recovery of sensible heat without sulphuric-acid condensation, so all three statements apply.
