Glossary

System to purify the cooled processed steam in the power plant.

Proposals for compact energy systems, planning, commissioning and operation of plants for energy supply and savings.

Tower-like structure at power plants which is used to cool down the cooling water heated up in the condensation process.

Wet chemicals purification system consisting of two small multi-functional process tanks (see Single Tank Tool).

Substances discharged into the environment (dust, gases, vapors, nitrogen oxide, sulfur oxides etc.) which arise from various processes (production, processing, combustion).

Number measurement of substance emitted in the surrounding.

Consumption of primary and secondary energy sources at the end user (industry, transport sector, households and small consumers).

Primary energy sources available in the upper layer of the Earth's crust. Apart from the term "reserves" the terms "resources" and "deposits" are frequently used, although the understanding of these terms varies widely.
Energy reserves can more clearly be classified into

• geologically proven and probable deposits, and
• currently exploitable deposits (exploitable in terms of economic and technical feasibility).

Energy source originating from primeval times, such as gas, oil, coal.

Collective term referring to coal, natural gas and petroleum; these materials were formed as a result of geologic processes from the remains of organic matter (plants and microbes).

Equipment to remove substances, such as salt, in water.

Solid residue from firing coal when melted by temperatures of over 1,500 °C.

Wet technology for purification systems in which two technological concepts are combined. The purification is performed in conventional purification tanks (see wet bank techniques) and also in two small multi-functional processing tanks (see Single/Double Tank Tool).

Gas occurring in carbonaceous rock, which mainly consists of methane (95 percent) and carbon dioxide (< 5 percent). It is released when hard coal is mined and is therefore extracted to the extent possible and used for the generation of heat and electricity.

Energy sources which do not need to be converted prior to use, e.g. hard coal and lignite, petroleum, natural gas.

Heating needed in the production process, for example, the chemical industry.

Wet chemical purification system, which, similar to a "dishwasher", exists of only one multi-functional process tank; the smallest in the world for this application. Cleaning, rinsing and drying are performed in one process module.

Sulfur dioxide quantities emitted to the environment.

Sulfur dioxide immission in a certain surrounding.

Closed vessel or arrangement of tubes used to generate high-pressure steam.

Plant used to generate electrical energy, which normally uses steam as working fluid for the thermal engine (turbine). The plant uses primary energy to generate steam whose heat energy in a thermal engine is converted into mechanical energy. A generator then converts the mechanical energy into electrical energy.

Equipment unit flown through by steam, used to convert the energy of the steam into rotational energy.
