Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler. Burning in suspension, the coal/air mixture provides the most complete combustion and maximum heat possible.
The rate of creosote build-up in a chimney depends on these factors: 1  The temperatures in the chimney or flue: A long low-smoldering wood fire produces more creosote than a hotter faster-burning wood fire. That's because burning wood at a lower temperature results in more incomplete combustion of the wood itself.
