  • Moving bed heat exchanger for circulating fluidized bed boiler
    Patent number: 9163829
    Abstract: A moving bed heat exchanger (155) includes a vessel having an upper portion (200), a lower portion (210) with a floor (272) including a discharge opening therein, and an intermediate portion (205). The vessel directs a gravity flow of hot ash particles (140) received thereby from the upper portion (200) through the intermediate portion (205) to the floor (272) of the lower portion (210) of the vessel, where the hot ash particles (140) are collected. Tubes in the intermediate portion (205) of the vessel direct a flow of working fluid in a direction substantially orthogonal to the direction of the gravity flow of the hot ash particles (140) through the intermediate portion (205) of the vessel such that heat from the hot ash particles (140) is transferred to the working fluid thereby cooling the hot ash particles (140).
