Explanation

The behavior of coal during combustion in a furnace is mainly determined by its proximate analysis, which includes moisture, volatile matter, ash, and fixed carbon content. While sulfur content, ash, heating value, and coal type are important characteristics, proximate analysis provides the most direct insight into how coal will perform under furnace conditions.
