    As characteristic properties of the chemical reactions carried out in a combustion flame, we can state as follows; because of the high reaction temperature, the reaction velocity can be kept in a high level.As the second property, we must sometimes stop the reactions rapidly, since the reacted materials are in many cases very unstable at such high temperature.In the standpoint of the reaction mechanism, the reactions are able to be classified in two groups, in the one of which the reactions in purpose are exothermic themselves, and in the another group, since the requested reactions are endothermic, we must let the second exothermic reaction take place in the same time or previously.In the latter case, the combustion reactions are greatly advantageous in designing the reactor.
    In this paper, I have picked up some typical examples in industry, which could be called the combustion reaction.As the exothermic reactions, the synthesis of hydrogen chloride and the one of nitric acid by ammonia oxidation are listed, and as the example in which the heat energy should be supplied from the other reactions, I have taken up, the synthesis of acetylen by the partial oxidation of methane and the one of cyanic.acid from ammonia, methane and oxygen, and etc.
    Furthermore, I believe some catalytic reactions in high temperature such as the form-aldehyde formation from methanol, and a series of hydrocarbon chlorination will be, allowed to belong to the combustion reaction according to the conception of this paper.As the last examples, the manufacture of raw gas for ammonia and methanol synthesis is also much favored by the combustion reaction, although it seems to be rather decompostion or reforming than synthesis.
    As a conclusion, I have tried to classify the combustion reactions in six groups from.the standpoint of the reactor type.

  • Rate of Heat Production of Gases

    Combustion properties are classified as follows;rate of heat production, flflame stability, completeness of combustion.
    Flame stability has been studied by many workers with stability diagram but there is no clear definition of the rate of heat production in spite of its familiar use.
    Author proposed J=cHυ as the rate of heat production where c is the concentration of the fuel in combustible mixture, H (Mcalmiddot;m-3) is the calorific value of the fuel, and υ (m/sec-1) is the flame propagation velocity of the mixture.
    The characteristics of J are discussed in this paper.

    In the previous report, it was clarified that the qualities of coke im-proved, owing to elevation of coking properties of coal during carbonization from a view point of coke manufacture and physical changes in coking process by briquetting low-or non-caking coal, as compared with non-briquetting.
    In this study, the author investigated the relation between briquetting pressure and the space of coal particles and moreover relative relations among briquetting conditions, the amount of α-picoline extracts of coal and characteristics of α-picoline extracts.From these results, coking mechanism of briquette coal has become clear.

  • Carbonization of Briquetts
    Relation of Volatile Matter and Heat of Carbonization
    Katsumi Nagasaka, Sachio Sugiyama

    About four kinds of briquett which differ one another in the quantity of volatile matter, the heat of carbonization was calculated from the combination of experimental data and equation derived by the authors.As the result, it was ascertained that the relation of direct proportion is nearly formed between the quantity of volatile matter and heat of carbonization.
    On the other hand, about kaolin, the heat of thermal decomposition was calculated using the same way for the purpose of examining above-mentioned values, and it became clear that the heat of thermal decomposition of kaolin can be calculated within the limit of error of a few percents deviating from the well known value.
    Consequently, it is believed by the authors that the values of heat of carbonization calculated are appropriate.
