Energy data are generally collected independently across different commodities, such as oil, natural gas or coal. As such, commodity balances provide the simplest way to present the data for one fuel together, expressed in physical units. This could be joules or cubic meters for natural gas or tonnes for coal, for example. This is the method used in the IEA's fuel information books on oil ...

In coal fired boilers the ash from the coal itself will be the makeup material. When firing bio fuels with very low ash content sand will be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions. CFBC uses crushed coal of 3 to 6 mm size. This requires only a crusher not a pulverizer.

The coking coals are used to make coke, a hard porous substance that comprises about 90% carbon with the balance being ash (non-combustible material), volatile matter and other impurities such as sulphur and phosphorus.

For example, when coal is burned at a power plant, the chemical energy present in the coal is converted to heat, which is then converted in the plant's generators to electrical energy. Eventually, the electrical energy is converted back into heat for warmth or used to turn motors. However, energy flows and transformation are also the cause of environmental problems.

An inert gas is a gas that does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample.
