Abstract: A device for measuring the moisture content of a moisture-containing sample, which includes an electronic balance for measuring the weight of an airtight sample holder containing the sample and placed on a receiver thereof. The sample holder has a side wall provided with a gas discharge pipe extending horizontally outwardly from therefrom. A gas feed tube having a front portion inserted into the gas discharge pipe of the sample holder is held without contacting with the inside wall of the discharge pipe. An infrared lamp is disposed above the electronic balance to heat the sample in the sample holder and to remove the moisture from the sample. By feeding an inert gas through the feed tube into the sample holder, the heating of the sample with the lamp is performed in an inert gas atmosphere.

Abstract: The present invention relates to a process for the production of a gas having a high heating value and a gasification furnace used for carrying out the process. The process of this invention is characterized in that a powdery coal is reacted with a hydrogen gas at a temperature of between 400.degree. and 900.degree. C. and a pressure of 20 and 100 Kg/cm.sup.2 in such a state that the powdery coal forms a layer on a dispersing plate from the surface of which the hydrogen gas is emitted and which is inclined so that the coal layer may move thereon in the down grade direction thereof. The gasification furnace of this invention is characterized by the provision of a housing 11 which defines therein a reaction chamber, and a dispersing plate 36 provided in the housing for dividing the housing into an upper space A and a lower space B and laterally inclined with a predetermined gradient.
