    The essence, of coal petrology ought to be the morphology of microscopic elements of coal. The form of those elements varies according to the kind and part of the vegetable as their original substance and to their conditions at the time of their sedimenta-tion. The defference in original matters and conditions at the time of sedimentation causes difference in the properties of macerals and their mixtures, microlithotypes.
    Based upon this notion, the reporter discusses the essential problems concerning the pre-sent stage of coal petrology, especially the defference between the National Committee and the Japanese Committee in the results as well as the processes of their work, and sets forth his position that basically he supports the orientation of the work being done by the Japa-nese Committee, chiefly because the National Committee takes too much interest in volatile matters and aims only at the coal distilation under the conditions limited within their spe-cific situations. While the reporter asserts that coal petrology should develop itself as a fundamental science of classification as against that of coalification, and as such should be made full use of in and for all the areas of coal science and coal utilization.

  • Application of Flash Technique for Study of Combustion
    Takeo Takahashi

    The author describes the apparatus and outline of flash technique (flash phtolysis and flash heating method) and its application for combustion. These methods are the most advanced methods for the study of reaction mechanism and of spectroscopies of free radicals in the reaction at high temperature and of high speed, but they are now scarcely putted to practical use in our country.
    As flash photolysis can be applied for gas system and flash heating method for liquid or solid system too, the flash technique will be gradually applied for wide range and then the unsettled problem of combustion mechanism will be solved.

  • Air Preheater Fouling by Heavy Oil Combustion in Power Station Boilers

    The fouling problems of heat conducting surface in boilers by the minor, components, for example, sulphur, vanadium and alkali in fuel have been more frequently discussed with the increase of sulphur contents in heavy oil and of the capacity of heavy oil firing boilers.
    The high temperature fouling of such heat conducting surface as a superheater will be more important in future with the use of high temperature and pressure boilers, but in this report, the fouling problems at present in low temperature heat conducting surface of an air preheater have been reviewed on the present status, formation mechanism and prevention methods of the fouling.

  • Determination of Corrosive Nature of Flue Gases

    Some of the modern boilers using heavy fuel oil have troubles due to the corrorsion of the low temperature heat exchange surfaces. The corrosion is generally caused by sulfur compounds in the fuel. Sulfur is oxidized to SO2 on combustion, and a small portion of SO2 is further oxidized to SO3. The SO3 causes a rise in the dew point of flue gases to the extent of 100 to 150°C, and the metal surfaces temperature of which is lower than acid dew point are corroded by condensed sulfuric acid solution.
    This paper shows the apparatus and methods to determine corrosive nature of flue gases; dew point, rate of acid build-up, concentration of SO2 and SO3, and rate of corrosion, which we have used in our reserch of the troubles in the oil fired boilers.

  • Industrial Experiments on Recovery of Phenols from Gas Liquor

    With proceeding of the modern industry, the contamination of effluent water from works is greatly concerned to social aspects. We have advanced some fundamental study about the ploblem of the treatment of industrial wastes since several years. By the aid of Government foundation we constructed a pilot plant capable to treat 5001/hr gas liquor at Kamaishi works, Fuji Iron and Steel Co. Ltd. in 1957.
    Now we report some experimental informations about the optimum operating conditions of extruction process by solvent.
