Study on the Geometric and Physical Properties of Coal Char During Combustion

摘要

A description for the variations of the size and density of the coal char based on the theoritical deduction is developed,without assuming that the size or density of the char particles is invariant. In order to check its validity,a test on the size and density of different types of coal in combustion is performed by use of the modern equipments and advanced methods. The data and model are reliable and practical.
