The mineralogical-geochemical investigation of the fly ashes has established an important platform for the development of strategies for utilization, marketing and sale of these industrial residues. The concentration of the selected ''high-technology'' elements is very low and does not suggest recycling processes. The content of toxic elements in t...
For the understanding of the combined action of the individual power plant components and of the combined action of power generators, power transmission systems and consumers, frequency/effective power control and potential/reactive power control are elementary concepts.
