Heat of Combustion Bomb Method

Standard Test Method For Heat Of Combustion Of Liquid Hydrocarbon Fuels By Bomb Calorimeter

(ASTM D240-17)

Scope:

This method will provide a measure of how much energy is contained in liquid petroleum hydrocarbons from light distillates to residual fuels. This can be expressed in many types of units including Calories, Joules, BTU, etc.

A thermal calorie is defined as the amount of energy required to warm one gram of air free water one degree Celsius as a result of the complete combustion of the sample. This can be converted to BTU (British Thermal Unit). There are 252 calories in a single BTU. The British Thermal Unit is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit.

To preserve samples for later analysis, adjust the sample pH to less than 2 with concentrated sulfuric acid (approximately 2 mL per liter). No acid addition is necessary if the sample is tested immediately. Keep the preserved samples at or below 6 °C.
Collect samples in glass bottles that have been rinsed several times with sample. Do not use plastic containers, which can adsorb quaternary ammonium compounds.

CALORIFIC VALUE OF REFUSE-DERIVED FUEL BY BOMB CALORIMETER

-Bomb Calorimetery (ASTM E711-87)

Scope:

The calorific value, or heat of combustion, is a measure of the energy available from the fuel. Knowledge of this value is essential in assessing the commercial worth of the fuel and to provide the basis of contact between producer and user.

This test method covers the determination of the gross calorific value of prepared analysis sample of solid forms of refuse-derived (RDF) by the bomb calorimeter method. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Calorific value is determined in this method by burning a weighed analysis sample in an oxygen bomb calorimeter under controlled conditions. The calorific value is computed from temperature observations made before and after combustion, taking proper allowance for thermometer and thermochemical corrections.
