Fuels are classified as primary and secondary fuel based on the ______

1.	Fuels are classified as primary and secondary fuel based on the __________(a) Capacity to burn(b) Availability(c) State(d) OccurrenceThe question was posed to me in an online quiz.The question is from Types of Fuels in division Steam Power Plant of Energy Engineering
Answer» Right option is (d) Occurrence Explanation: BASED on the occurrence, fuels are classified as primary fuels and secondary fuels. A primary fuel is available in NATURE E.g., wood, peat, lignite, natural gas, petroleum, etc. A primary fuel is also CALLED as a natural fuel. A secondary fuel is not available in nature, but it is prepared from primary fuel by artificial means e.g. gasoline, diesel, coke gas, blast FURNACE gas, kerosene etc. A secondary fuel is also known as artificial fuel.
