Most of the mineral matter in fossil fuels such as coal or lignite is converted during combustion to a fused, glassy bottom ash which presents no air pollution problems. Smaller ash particles called fly ash enter furnace flues and, in a properly equipped stack system, are collected efficiently. However, some of the fly ash particles escape through the stack and enter the atmosphere. Unfortunately, these tend to be the smaller particles which do the most damage to human health, plants, and visibility. 1, record 1, English, - ash%20particle
