Abstract
A process for optimizing the ash separation and cooling
operation of a fluidized bed gasifier which produces a
mixture of ash and char from a carbonaceous material,
comprising the steps of feeding the carbonaceous material
to a gasifier at a first rate, discharging the mixture from the
gasifier at a second rate approximately equal to a rate of
introduction of ash contained in the carbonaceous material
fed into the gasifier, maintaining the discharge temperature
of the mixture below a temperature T, injecting a first gas at a
first elevation within the gasifier, injecting a second gas at a
second elevation which is above the first elevation to
refluidize a portion of the mixture, measuring the ash content
of the discharged mixture, and measuring sintering of ash of
the discharged mixture; characterized by the further steps of
(1) raising the second gas injection elevation to increase the ash content of lowering the second gas injection elevation to reduce sintering of the discharged ash, and
0(2) repeating the above process until both ash content and sintering of ash of the discharged mixture is acceptable.
(1) raising the second gas injection elevation to increase the ash content of lowering the second gas injection elevation to reduce sintering of the discharged ash, and
0(2) repeating the above process until both ash content and sintering of ash of the discharged mixture is acceptable.
