The solid
fuel having the highest calorific value is
Wood
Lignite
Coke
Anthracite
Anthracite
●The
calorific value or the heat value of a solid, liquid or gaseous fuel is defined
as the number of heat units developed by the complete combustion of unit mass
or unit normal volume of a given fuel.
●Anthracite (coal-like)
is a hard, very low content of volatile compact variety of coal
that has a high luster.
It has the highest carbon content (between 92.1% and 98%),
the fewest impurities and the highest calorific content of all types
of coal, which also includes bituminous coal and lignite.
Hence, the correct option is (D).
&Key Points:-
Calorific
value is nothing but the energy contained in a fuel or food, determined by
measuring the heat produced by the complete combustion of a specified
quantity of it. This is now usually expressed in joules per kilogram.
Hence, hydrogen has the highest calorific value.
