Question

What is the heating value of a number 2 heating oil?
a) 80,000 btu/gallon
b) 100,000 btu/gallon
c) 140,000 btu/gallon
d) 180,000 btu/gallon

Answer 1

Correct option is C. The heating value of a number 2 heating oil is 140,000 btu/gallon.

• The amount of heat released by combusting a specific quantity of fuel (at first at 25°C) and raising the temperature of the combustion products to 150°C is known as the lower heating value (also known as net calorific value) of a fuel.

• This definition assumes that the latent heat of vaporization of water in the reaction products is not recovered.

• When a fuel is burned and the combustion products have returned to a temperature of 25°C, the higher heating value of the fuel—also known as the gross calorific value or gross energy—is calculated, taking into account the latent heat of vaporization of water in the fuel and the amount of heat released by a specified quantity (which was initially at 25°C).

• British thermal units are BTUs, while standard cubic feet are SCFs.
