SYNOPSIS: -Recently, various solid fuels combustion experiment have been carried out on the commercial scale experimental combustion equipment which was developed by auth-or's company for porpose of useful application of low grade fuels in our country.
Hokusyo coal and another few fuels was choosed for sample fuels of new developed fluidized combustion method.
In chemical industrial process, fluidization is very widely developed technics, and author explored the developement of new combustion mechanisms by aerodynamical and thermod-ynamical principles of fluidized reactions.
First commercial prototype large steam generator with fluidized combustion chamber is under successful operations and we hope this mechanism will serve as a tool to useful application of low grade coal in future.

SYNOPSIS: -The author describes several problems on the combustion of heavy oil from results of his studies and some references. The items reviewed are as follows:
1) The combustion velocity and growing heat in the heavy oil combustion.
2) The influences of fuel's properties upon the spray size of fuel and the deposition of carbon.
3) The microgram quantity of contents in fuel as catalyst in the heavy oil combustion.
4) The corrosion by vanadium and sulfer in fael.

Since June 1957, the Energy Group Committee of Technical Council (annexed to the Agency of Industrial Science and Technology) has been taking a synthetical and systematical counter-measure against the technical problems on energy development.The Group Committee (Head, Shinzo Okuda) proposed on March 23, 1959 a report to the Director of the Agency, the full text of which has been compiled and published by the Japan Power Association entitled, “Recent Problems of Energy Development”.
In this paper, the author based on the Report outlines the recent technical counter-meas-ure of energy in Japan.

In this third report, the reporter has studied statistically the relation between the moisture and the ultimate analytical values in various coals, examining the relation of the moisture to hydrogen content and that to oxygen content separately;he has eliminated the relation between these contents with partial correlation analyses.The infer ence drawn from the study is as follows:
(1) In the area covering brown coal and anthracite, the retation of the moisture to the carbon weight percentage is similar to the relation of density to the carbon weight percen-tage.But the minimum value of the moisture slips off that of density in connection with the carbon weight percentage.
(2) The moisture of coals whose carbon weight percentage is lower than that at its minimum has a positive interrelation chiefly with the oxygen content, and scarcely has any correlation with hydrogen.
(3) In contrast to that, the moisture of coals whose carbon weight percentage is higher than at its minimum has a negative interrelation with hydrogen content.Excepting the coals in which is contained extremely small amount of hydrogen, i.e.whose H/C atomic ratio is less than 0.2, the amount of oxygen has scarcely anything to do with it.
(4) In the low-coalification coals, physical adsorption prevails, whereas chemical ad-sorption comes to gain importance as the coalification proceeds.
(5) In respect to the moisture too, peat and lignite are proved to have quite different qualities from the coals of the area covering brown coal and bituminous coal.
(6) Though the moisture contained in peat has close relation with the chemical com-ponents of peat, such relation is hardly discerned in lignite.
