  • Device for transferring solid particles
    Patent number: 5106238
    Abstract: A device for transferring solid particles from an area of higher pressure to one of lower pressure. A stack-up section (3) between the areas is full of particles and large enough to reduce the current of gas flowing through the open stack-up section from the area of higher pressure as a result of the pressure loss that occurs in the stack-up section to a level that prevents pneumatic conveyance of the particles. A conveyor is in or at the end of the stack-up section.

  • Fluidized-bed furnace that recirculates solids
    Patent number: 4917025
    Abstract: A fluidized-bed furnace recirculates solids by way of one or more cyclone precipitators (6), the solids outlet of which communicates with the fluidized bed (4) by way of a trap (8) and a directly downstream chute (10). The coal intake opens into the chute. The outlet (9) from the trap (8) communicates with the chute (10) through a transitional section (11). The transitional section tapers out from the outlet from the trap and then in to the chute. The coal intake is above the wider section of the transitional section.
