Methods and apparatus for heating particulate material |
摘要 |
A method and apparatus are provided for heating and/or drying particulate materials such as coal wherein the particulates are fed into a direct heating fluidizing chamber, carried in a stream of heated oxygen-free gas at a temperature sufficiently high to heat the particles to a preselected temperature. The particles are then removed from the gas stream at the preselected temperature and then the gas is reheated in a heat exchanger and recycled. Where the particulate material to be dried yields a vapor, such as steam, the vapor is used as the transport or fluidizing gas. Means are provided for removing and/or condensing such vapor beyond the amount needed for fluidization.
