A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
~ mechanical load, e.g. electric generator. A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, [1] [2] etc.) for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source. [3] Such recirculating turbines follow the Brayton cycle. [4] [5]
Processing of biomass waste into combustible syngas for electric power and heat [14] or for synthesis into fuels or chemicals. Production of value-added products (metals) from slag [15] Safe means to destroy both medical [16] and many other hazardous wastes. [1] [17]
Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [10] Argon is the third most abundant ...
Argon: Ar 0.2 [4] Not Non-electron attaching, not efficient in slowing electrons. vacuum: High vacuum is used in capacitors and switches. Problems with vacuum maintenance. Higher voltages may lead to production of x-rays. [7] [8] *
The conversion is based on a Traveling-Wave Direct Energy Converter (TWDEC). A gyrotron converter first guides fusion product ions as a beam into a 10-meter long microwave cavity filled with a 10-tesla magnetic field, where 155 MHz microwaves are generated and converted to a high voltage DC output through rectennas .
The lower sustaining power setting is achieved with high r.f. frequency, low pressure, and monatomic gas, such as argon. Once diatomic gas is introduced into the plasma, the sustaining power would be drastically increased, because extra dissociation energy is required to break gaseous molecular bonds first, so then further excitation to plasma ...
Efficiency of power plants, world total, 2008. Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges ...
