Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter
Introduction:
1.1 This method-for heat of combustion is basically similar to ASTM Method D240
modified only to provide greater precision. With the development of supersonic
jet fuels and their narrow specification ranges, the limits given in ASTM D240
of repeatibility of 55 BTU per pound and reproducibility. of 175 BTU per pound
were not suitable.
2.1 This method was primarily developed for supersonic jet fuels; however, it may
also be used for other fuels,, and volatile or-non-volatile solids and liquids.
3.1 Heat of combustion-is determined in this method with an adiabatic calori-
meter and by burning an-accurately weighed sample in-an oxygen. bomb. The heat
rise is measured by a resistance thermometer under closely controlled conditions,.
The heat of combustion.is computed from:temperature observations before, during,'
and after combustion with.allowance for thermo-chemical.and heat transfer corrections.
Definitions and Units:
4.1 The energy units in this method are defined'as follows:
4.1.1 One calorie (International Steam Table Calorie) equals 4.1868 absolute_
joules.
4.1.2 One BTU (British Thermal Unit) equals 251.996 calories or 1055.07
absolute joules. I
4.2 Heat of combustion, computed in calories per gram and converted to British
Thermal Units per pound (one calorie per gram equals.1.8 BTU per pound).
4.3 Energy Equivalent (effective heat capacity or, water equivalent) of the 'calori-
meter is the energy. required to raise the temperature one degree, expressed as
e
1
a oriel per degree Centigrade.
4.4 Temperatures shall be recorded in ohms or other units; however, the same units
must be used in all. calculations, including standardization.
