brown coal drying

Brown coal, broad and variable group of low-rank coals characterized by their brownish coloration and high (greater than 50 percent) moisture content. These coals typically include lignite and some subbituminous coals.In Great Britain and other countries, the termbrown coalis used to describe those low-rank coals (lignite and subbituminouscoal) that generally have abrowncolour.

As a result,brown coalprovides only 25% of the heating value of blackcoal, but has a low sulphur and ash content compared to black coals. Reducing the moisture content ofbrown coalbydryingimproves energy efficiency and reduces emissions ultimately producing a much more efficient blackcoalequivalent product.

Drying brown coalin this way has the potential to far exceed the greenhouse gas savings from the Federal Government’s Mandated Renewable Energy Target Scheme (MRET), saving 9 million tonnes of CO2 a year if applied to remove half of the lignite water in existing power stations, against the MRET target of 6.5 million tonnes, he said.

Dryingthebrown coalsignificantly reduces its adsorption capacity for cationic dye, supporting the hypothesis ofcoalshrinkage and the consequent reduced pore volume upondrying. These findings suggest that raw (wet)brown coalmay perform as well as activated carbon for the removal of positively charged species in aqueous solution.

Lignite, orbrown coal, is the lowest-rankedcoal, and is placed just above peat in terms of calorific value. It is not a feature of international seabornecoaltrades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which ...

To diminish the effect of functional groups ondrying,dryingbehaviors and pore structures of only one kind ofcoaldried at different heating rates and atmospheres were investigated. The finaldryingtemperature was kept constant.
