3.1 Comparison of calorific value
Fig.5 shows comparison of calorific value of different oil at definite temperature. From this figure it is shown that
the calorific value of the extracted pine oil is higher than the calorific value of pyrolytic pine oil but lower than that
of diesel fuel. The pine oil is favourable than other oils because water is not added in solvent extracted pine oil
whether water is added in pyrolytic oil by hydrolysis reaction. Since higher calorific value is one of the important
parameter for using the oil as fuel and also for better performance, extracted pine seed oil can be used as an
alternative fuel.
