The quantity of combined water in Korean anthracites has been investigated at various temperatures below 200℃ by the thermogavimetric method in the nitrogen atmosphere. The results were as follows; 150℃…0.3~0.5%, 175℃…0.1~0.2%, 200℃…0.06~0.1%, On the other hand, the combustion rate of briquttes depends upon the characteristic of it's kind. The rate was rapid in the state of proper moisture than dry and the effusion velocity of oxygen in dry briquttes was larger than the moistured, but the effusion velocity didn't relate to the combustion rate directly.
