Slag Flow - an overview | ScienceDirect Topics
The gasifier features a dry feed system. Coal is ground and dried, and N 2 is used to pressurize the feed hoppers to the gasifier operating pressure, about 4.2 MPa. Coal is fed to opposite sides of the gasifier, near the bottom. Oxygen is fed to the gasifier below the coal injection points. Slag flows out the bottom.

Coal gasification - Wikipedia
Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4) , and water vapour (H 2 O)–from coal and water, air and/or oxygen.
Effect of coal properties and operation conditions on flow ...
In the radiant syngas cooling, the hot gas flows into a radiant boiler where steam is generate for steam turbine. The slags are dropped to water bath at the bottom of the gasifier. The boiler is expensive and may have a fouling problem. In the water quench, the hot gas and slag are cooled in the water bath.
Correlating The Slagging of A Utility Boiler With Coal ...
the type of information available to coal producers and utilities. THE PLANT The plant, although anonymous, can be described as a large pulverized coal unit with a high heat release per unit volume. This design constraint limits the coal used to high fusion central Appalachian coal, typically in the seven to ten percent ash range.
Developments in modelling and simulation of coal gasification
The gases flow upwards through the bed of coal and the slag is withdrawn through the bottom. In a fluidised bed gasifier, the coal is gasified in a bed of heated particles suspended in flowing air. In an entrained flow gasifier, the pulverised coal and the gases flow concurrently at high speed.
Coal Drying Improves Performance and Reduces Emissions
When high moisture coals are burned in utility boilers, about 7 percent of the fuel heat input is used to evaporate fuel moisture. This results in higher fuel flow, higher stack flue gas flow, higher parasitic power, lower plant efficiency, and higher mill maintenance costs compared to low- moisture coals.
