Includes all processes for the production of electricity from primary energy sources. Electricity is normally produced by a turbine-driven alternator. These can be steam, gas, water or wind turbines. Steam can be produced conventionally by heating water using fossil fuels, renewable sources (biomasses), solar radiation or geothermal sources. Alternatively, steam can be produced with a non-conventional method using thermal energy released from nuclear fission reactions. Gas turbines use the energy generated from burning natural gas. In combined cycles, gas turbines are usually linked to steam turbines for cogeneration of electricity. Water turbines use the movement of water (hydroelectric) and wind turbines use wind strength. The main process in which hexagonal mesh and anchors are used is:
The objective of gasification is to produce syngas from a wide range of compounds containing carbon, such as for example, coal, heavy refining residues and biomasses.
In the IGCC (Integrated Gasification Combined Cycle), the syngas produced by gasification is used as fuel for the combined cycle gas turbine to produce electricity. Also, the syngas produced by gasification is cooled, the heat is recovered in a Heat Recovery Steam Generator (HRSG) and the steam produced is used by the steam turbine to produce more electricity (cogeneration).
Hexagonal meshes are used for armouring the refractory linings of syngas gasifiers.
