  • Cleaning of Dukki (Baluchistan) coal by oil agglomeration process

    Cleaning of coal fines by oil agglomeration is an efficient technique by which an appreciable recovery of combustible matter and significant reduction in ash forming minerals are possible. In this study, oil agglomeration process has been employed to clean indigenous coal under the influence of parameters such as oil type, particle size and the pH value of aqueous medium. As agglomerant, castor ...

  • Studies on coal flotation in flotation column using statistical technique

    Flotation of Indian high ash coking coal fines to obtain clean coal has been reported earlier by many authors. Here an attempt has been made to systematically analyse factors influencing the flotation process using statistical design of experiments technique. Studies carried out in a 100 mm diameter column using factorial design to establish weightage of factors such as feed rate, air rate and ...

  • Hydrophobic aggregation of fine particles in high muddied coal slurry water

    The hydrophobic aggregation of fine particles in high muddied coal slurry water in the presence of four quaternary ammonium salts of 1231(dodecyl trimethyl ammonium chloride), 1431(tetradecyl trimethyl ammonium chloride), 1631(cetyl trimethyl ammonium chloride) and 1831(octadecyl trimethyl ammonium chloride) was investigated through the measurement of contact angles, zeta potentials, ...

  • Chemical kinetics parameters of nuclear graphite gasification

    This paper provides chemical kinetics parameters for the gasification of nuclear graphite grades of IG–110, IG–430, NBG–18 and NBG–25 and presents empirical correlations for their surface areas of free active sites as a function of mass. The kinetics parameters for the four elementary chemical reactions of gasification of these grades of nuclear graphite include the values ...

  • Misunderstanding about the operation of the factory boiler

    The boiler is a very common equipment in the factory. LNEYA Xiaobian tells everyone that many people have misunderstandings about it.Misunderstanding 1 The higher the steam pressure, the better.The choice of boiler steam pressure depends mainly on the needs of the user. The steam pressure is low, the safety of the pressure-bearing parts is favorable, the energy consumption is also low, and the ...

  • Formation and emission of fine particles from two Danish pulverised coal fired power plants

    ABSTRACT Measuring campaigns at two Danish pulverised coal fired power plants has been performed. The power plants are equipped with the same type og flue gas cleaning devices. The concentrations and chemical compositions of the formed particles were similar for the two plants. The measurements were performed simultaneously at three locations including both total dust measurements and ...
