Combustion of the pulverized fuel in suspension in the furnace, the combustion temperature being less than the melting of the ashes.

Burning of pulverized fuel in suspension in the furnace, the combustion temperature being higher than the melting of the ashes.

An organ whose function is to conduct the operation of the installations of a network.

Room in which the control panels of an installation are installed.

Energy that is the object of a commercial transaction, which facilitates its quantification.

Vertical installation connecting two or more floors or allowing access to a floor. These wells do not communicate with the surface.

Compressive Strength (for agglomerates prepared in the dive press): Maximum test pressure referred to the usable surface of a test diver for which the sample of the fusion agglomerate departs under specified conditions. Punctual resistance (for agglomerates made in the cylinder press): Resistance of the agglomerate to which an approximate point force is applied until it departs under certain conditions.

Relation between the opening of the concentrator and the area of the absorber.

In the International System of Units (SI) the microgram per cubic meter (g / m 3 ) is used as the unit to express the mass concentration of air pollution (mass per volume). Likewise, milligram per liter (mg / l) or gram per cubic meter (g / m 3 ) is used for water pollution. The difference in the powers of ten for the units is explained by the difference in densities between air and water. On the other hand, numerous concentrations are expressed in parts per million (ppm), parts per hundred million and parts in billions, with the proportionality of parts generally being volume-based. In order to convert the ppm to g / m 3 it is necessary to consider the fact that one mole of gas at normal temperature and pressure occupies a volume of 0.0224 m < 4 L). Thus, the mass concentration expressed in mg / m 3 is equal to: (cx M ) / 10.0224 where c is the concentration in ppm and M R the relative molecularmass of the pollution (old molecular weight). Example: The relative atomic mass of sulfur is 32 and that of oxygen 16. The relative molecular mass of sulfur dioxide (SO <2) is therefore 32 + 2x16 = 64. A mass concentration of sulfur dioxide In air is therefore: (1 x 64) / 0.0224 g / m 3 = 2857 mg / m 3. The abbreviation ppm should be avoided because it is ambiguous (ppm = part per thousand, per million, per billion) and because it is not known whether it is a mass or volume concentration.

Part of the concentrator solar collector that focuses on incident solar radiation.

Focus on a plasma, method used to keep the particles of a plasma in a given region of space. Note: There are two main types of confinement: magnetic confinement, which can be considered as static, and inertial confinement, which is of the dynamic type.

Time required for the plasma temperature to fall to a certain fraction of its starting temperature if no additional heat has been supplied.

Official evidence of the quotas of all essential parts of a hydroelectric exploitation, especially those of the reservoir.

Refers only to the power values of the facilities corresponding to the consolidation perimeter of the company's accounts.

Categories of energy end-users, generally disaggregated as follows: industry (often outside the energy industry) and often disaggregated into large consumer industries such as metallurgy (steel and non-ferrous metals), chemical, petrochemical and other industries, commercial or tertiary sector (Trade and services), public sector or administration, agriculture (including fishing, hunting and forestry), domestic or residential sector and transport. Note 1: It should be noted that the transport sector covers all transport, including those dependent on industry, commerce and services, public sector or administration, agriculture or domestic, all transport of persons or goods For their own account or for the account of others. Seaports are, in principle, excluded from transport. Note 2: Decomposition in consumer sectors and subsectors may vary from balance sheet to balance sheet.

Annual consumption of drinking water from the public network intended for human consumption used in EDP Group companies. Excludes buildings located within Substations or producer centers.

Annual consumption of electricity used in the administrative services of EDP companies. Excludes buildings located within Substations or producer centers.

Total annual water consumption used in thermal production facilities, including total volumes of raw water (for processes).

Sum of the total humidity with the ash content considered in the hydrated fuel and with its ash. Note: By contrast, pure coal is defined in some countries.
