Coal Combustion and Gasification ![]() Recently, there has been increased focus in the U.S. and internationally on the development of high-efficiency, ultraclean processes for converting coal to electricity or hydrogen. As a consequence, Sandia is conducting research on two of the most promising processes for utilizing coal: oxy-fuel combustion and coal gasification. In support of this work, a new laboratory is being constructed to allow the investigation of pressurized coal combustion and gasification. Research on coal combustion and gasification at Sandia is led by Chris Shaddix and Linda Blevins. Coal Combustion Research ![]() Coal Gasification Research Coal gasification offers advantages over traditional coal combustion technology in the areas of thermal efficiency (when coupled with a gas turbine combined-cycle power plant), reduced emissions, and the ability to generate hydrogen or other high-value fuels or chemicals. Although small-scale coal gasification has been used in the petrochemical industry for decades, the proper design and operation of large-scale units for utility power production is poorly understood. Sandia is using its expertise in laser and optical diagnostics and chemical kinetic modeling to perform the first measurements of coal char gasification kinetics at high-temperature, pressurized conditions. These measurements will allow more accurate computational fluid dynamic (CFD) modeling to be performed for the design and operation of high-temperature gasifiers. |
