1 ABSTRACT Boy's Gas Calorimeter is designed to ensure that the heat from the burner flows up through the center of the calorimeter container and back down again inside the container and back up again before exhausting. This design ensures maximum heat transfer to the cooling liquid and hence accurate measurement of calorific value of gas. The amount of heat liberated when a unit mass of fuel is burnt completely is known as the calorific value. This calorific value of gaseous fuel is determined using boys gas calorimeter. The actual calorific value of LPG,propane and butane are113.92 MJ/m3 , 95.8 MJ/m3 , and 126 MJ/m3 . With this value, we can identify type and method that can be use to optimize energy and produce complete combustion to minimize heat losses to surrounding. Burner type and flame velocity can be determined to decrease the heat loss and complete combustion can be optimized. INTRODUCTION When the hydrocarbon fuel is being combusted under specified condition, there are amount of heat released that is known as calorific value. The calorific value (CV) or heating value (HV) of the hydrocarbon fuel is depends on the composition of the gas. There are two types of calorific value of hydrocarbon fuel. It can be classified as 1. Gross or Higher Calorific Value (HHV or HCV) – can be classified when the combustion product, water is in liquid form where there are water vapor in flue gasses. 2. Net or Lower Calorific Value (LHV or LCV) – can be classified when the combustion product, water is in vapor form where during its phase changing to vapor, there are difference between HCV and the latent heat. In calorific value, the measurement unit of energy per unit of the fuel involve are: Btu/lb, J/kg, kcal/kg...
