    摘要： Disclosed is a process for cooling hot exhaust gases. The process gases are supplied to a stationary fluidized bed, which contains cooling elements and is contained in an annular trough. Fluidizing gas is supplied to the stationary fluidized bed through the permeable bottom of the trough. The hot process gas is passed through the central opening in the fluidized bed. Cooled solids flow from the fluidized bed across the inner rim of the trough into the process gas stream and are entrained by said stream into the dust-containing space over the top surface of the fluidized bed. The solids which are separated in the dust-containing space fall back into the annular fluidized bed, and the cooled gas which contains the remaining solids is supplied to a gas cooler, which is provided with cooling surfaces. The gas which leaves the upper portion of the gas cooler is fed to a solids separator and the separated solids are recycled to the stationary fluidized bed.

    摘要： A process for the partial combustion of finely divided coal at high temperature and pressures to make synthesis gas having entrained particles of fly ash which are separated from the gas at high pressure. The fly ash and a minor amount of entrained gas are handled in a batchwise manner to isolate a batch in a lock hopper, depressurize the batch, strip the synthesis gas from the fly ash and cool the fly ash prior to disposal. During the depressurizing steps, the kinetic energy represented by fluids flowing from the pressurized lock hopper is utilized to provide power to a pressure recovery means and do additional work. The additional work is used to aid in the pressurization of a second lock hopper. In an alternate embodiment the additional work may be used to aid in fluidizing the particulate coal flow to the burners of the gasifier.
