Danylenko S. Prestarting and thermal indicators of roasting aluminium electrolyzers

The dissertation on competition of a scientific degree of Cand.Tech.Sci. on a speci-ality 05.17.08 - processes and the equipment of chemical technology. - National technical university of Ukraine "Kyiv polytechnic institute", Kyiv, 2012. The dissertation is devoted to complex research of temperature-thermal modes of roasting electrolytic cells various types at roasting by Joule heating and products of com-bustion of liquid fuel. The technique is developed and complex experimental researches of temperature modes industrial electrolytic cells with the self-burning and burnt anodes are lead. On the basis of research of temperature-thermal modes of roasting with use pilot in-stallations rules are developed at use of hot filled and cold filled hearth of the masses which working off is carried out on plants "HOTWORK" at their use for roasting electro-lytic cells with the burnt anodes. The technique of determination dimensionless medium volumes temperatures of hearth is developed and the generalized dependences of dimensionless temperature on di-mensionless time (number of Fourier) are received for practical use. Keywords: aluminum electrolytic cell, hearth, temperature, roasting, rate of heating, stuffed seams, the coking, the accumulated heat, numerical modeling numerical simula-tion, power efficiency.
