Coal Drying Improves Performance and Reduces Emissions
2017-9-6 · COAL DRYING IMPROVES PERFORMANCE AND REDUCES EMISSIONS1 Charles Bullinger and Mark Ness Great River Energy Although lignite power plants are designed to burn coals containing 40 percent or more moisture, a reduction in coal boiler efficiency increases as fuel moisture content decreases due to a decrease in the flow rates of fuel
2015-9-10 · lignite sulfur to SOx is generally inversely proportional to the concentration of alkali constituents in the lignite. The alkali content is known to have a great effect on sulfur conversion and acts as a built-in sorbent for SOx removal. Nitrogen Oxides Emissions - The NOx emissions from lignite combustion are mainly a function of the boiler
