Fuels can be classified as solids, liquids, and gaseous types. Unlike gaseous and liquid fuels, most solid fuels (with the exception of petroleum cokes) contain appreciable percentages of __________ compounds.

The __________ content in solid fuels is often considerably higher than is characteristic of gases and liquids.

TRUE or FALSE: The chemical elements present in solid fuels are not the same as those in gaseous and liquid fuels.

Which of the following solid fuels does not belong to the group?

The highest rank of coal is __________.

In the __________ analysis, the composition of fuel is reported based on the differences in volatility of the components of the solid fuel.

The volatile combustible matter (VCM) in proximate analysis includes __________.

The loss in weight of dry sample after complete combustion of the remaining fuel for 2 hours at 500 to 815 degree Celsius corresponds to __________.

TRUE or FALSE: The combined water in modified analysis is equivalent to the oxygen of the ultimate analysis.

For the modified analysis, the available or net H2 also refers to the combustible or burnable hydrogen.

Which correlation is used to estimate the HHV of the fuel given its ultimate or modified analysis?

When using the proximate analysis of a fuel, the higher heating value of the fuel comes from the higher heating value of the fixed carbon and volatile combustible matter.

What is the name of the solid residue formed when burning solid fuels?

For incomplete combustion, the refuse consists of ash and __________.

For uncoked combustibles, the refuse contains ___________.

For coked combustibles, the refuse contains __________.
