Advanced Melting Technologies with Submerged Combustion
by L.S. Pioro, I.L. Pioro, B.S. Soroka and T.O. Kostyuk
This technical book is devoted to the development and design of advanced melting technologies with submerged combustion.
The main advantages of submerged combustion, i.e. the combustion of gas-air or gas-air-oxygen mixtures directly inside a melt, include achievement of the maximum heat transfer from combustion products to the melt to improve mixing and to increase the rate of chemical reactions. Based on these advantages, advanced melting technologies were developed and tested in various industries.
The book consists of ten chapters covering the development, design, testing, and industrial application of various advanced melting technologies with Submerged Combustion Melters (SCMs) for production of materials for the building industry from metallurgical slag; coal slag and ash from coal-fired thermal-power plants. Subjects discussed include the fuming of slags of non-ferrous metals; melting silicate materials; production of mineral wool; production of molten defluorinated phosphates for agriculture; pyrohydrolysis of fluorine-containing wastes; vitrification of high-level radioactive wastes; and production of expanded-clay aggregate for lightweight concrete from non-selfbloating clays.
Eight appendices contain additional material related to submerged combustion, covering topics such as theoretical investigation into the effect of melt turbulization on discrete particle dissolution rate; SCMs heat losses through water-cooled walls; heat transfer enhancement in glass melting furnaces; other submerged combustion apparatuses, etc.
Many of the developed melting technologies are intended to decrease the harmful effects of various wastes such as slags, ash, etc. on the environment by effectively reprocessing them into materials for the building industry.
This book is intended for specialists, engineers, designers, researchers, and scientists working in heat engineering, power, chemical, metallurgical and building industries, environment protection and other areas where non-ferrous melting apparatuses and gas burners are used.
