Lignite, or brown coal, is the lowest rank of coal and used almost exclusively as fuel for electric power generation. Jet, a compact form of lignite, is sometimes polished and has been used as an ornamental stone since the Upper Palaeolithic. Sub-bituminous coal, whose properties range from those of lignite to those of bituminous coal, is used primarily as fuel for steam-electric .

In a Boiler firing bituminous coal the maximum moisture content is in the range of 20 % . For drying this moisture around 30 % of air heated in the air heater to around 320 ° C is used. Lignites with around 45 % to 55 % moisture require much more heat to remove the moisture. Lignite boilers use recirculated Flue gas from the top of the furnace to heat and remove the moisture.

Lignite coal power plants compete in the merit-order with hard coal and gas plants. In the merit-order curve they are positioned as a "low-production-cost" increment, right next to nuclear generation. Costs of renewables influence renewable generation capacity, and thus reduce the residual load. Also, besides nuclear, high carbon dioxide emissions of lignite power make lignite .

Carbon Dioxide Emission Factors for Coal

Traduire cette page

The typical carbon content for coal (dry basis) ranges from more than 60 percent for lignite to more than 80 percent for anthracite. Although hydrogen generates about 62,000 Btu per pound, it accounts for only 5 percent or less of coal and not all of this is available for heat because part of the hydrogen combines with oxygen to form water vapor. The higher the oxygen content of coal, the ...
