Abstract
PURPOSE: To obtain smokeless, non-polluting coal which saves the necessary amount of coal by half, by adding powder of a compound of quartzite and fluorite as a catalyst to mined coal.
CONSTITUTION: Mined coal is added with powder of a compound of quartzite and fluorite as a catalyst to supply the deficiency of oxygen during the combustion. The coal thus obtained can be burnt without emitting smoke and toxic gas caused by the deficiency of oxygen. The process is an application of "Complete combustion process using compound of quartzite and fluorite" disclosed in Japanese Patent Opening Number 54-31632.
