  • Pneumatic conveying dryer for carbon fuel
    Patent number: 9663738
    Abstract: Provided is a carbon fuel pneumatic dryer in which synthesis gas generated in a reactor is fed and cooled, including: a feeding part formed as a narrow pipe, via which synthesis gas and carbon fuel are fed; a drying part formed as a pipe having a larger diameter than the feeding part, in which the hot synthesis gas fed via the feeding part is cooled and the moisture content of the carbon fuel is lowered; and a conveying part formed as a pipe having a smaller diameter than the drying part such that the flow velocity of the synthesis gas and the carbon fuel having passed the drying part is increased, wherein the conveying part includes a bend so that the flow direction of the synthesis gas and the carbon fuel is changed.
