The Relation among the Conditions of the Artificial Coalification : Fuel ratio, Coalification Temperature, Coalification Index and Coalification Velocity Index

摘要

The author has been investigating on the coalification in the wood of the Submerged Forest of Uozu and it wi1l be a suitable sample for the study of the coalification process previous to the peat formation.The obtained results are as follows:-1. The artificial cùal property is determined by the cmlification temperature, the coalification index and the coalification velocity index. The Iast factor is more serious but hitherto is not so much considered.2. Using Uodu Submerged Forest Wood, under the coalification index 0.69, the fuel ratio of the artificial coal increases with coalification velocity index increase.3. Though coalification index comparatively being low, the coalificatiün reaction is accelerated extremely by greater increase of the coalificatiün velocity index.
