Abstract
In the pre-heating of coal the coal is entrained and/or fluidized in a heat exchange chamber by a heat-transfer gas which pneumatically conveys the coal from the chamber through a duct to a separator in which the coal is separated from gas. A hydrocarbon binder in a liquid state is injected into the coal in the duct through which the coal is being pneumatically conveyed by the gas to the separator.
