The Science of Victorian Brown Coal | ScienceDire

The solids fraction of brown coal is a complex, heterogeneous mixture of plant remains, and each component of the mixture has its own physical and chemical characteristics. Victorian brown coal is very low rank: It has passed through the rotting and humification stages of coalification, but it has not been subjected to the higher temperatures ...


Victorian brown coal is the single largest source contributing to the electricity needs in Victoria. However, its combustion is also the major contributor for greenhouse. In particular, the abundant moisture in Victorian brown coal, up to 70 wt%, is the major cause increasing its carbon emission rate per electricity output.

Burning characteristics of Victorian brown coal under MILD .

Typical Victorian brown coal-fired system plants are characterized by a high emission intensity (≈1.22 ton-CO 2 /MWh) and NO x emissions (≈650 ppmv) , that hampers the utilization of this coal. Thus the efficient use of Victorian brown coal and its impact on the environment remains a major challenge.

Explosibility Characteristics of Philippine Coal Du

The explosion behaviour and physical characteristic of Philippine coal dust was analyzed. Experiments for explosibility were performed to measure the overpressure,P max, deflagration index, K st and flammability limits of Philippine coal dust/air mixtures in a standard 20 L spherical bomb. The coal dust/air mixture was ignited by chemical ignitor of 5 kJ.

The macerals, including fusinitic coal containing 72.20% inertinite and xyloid coal containing 91.43% huminite, were separated from Shengli lignite using an optical microscope, and their combustion reactivity was examined by thermogravimetric analysis. Several combustion parameters, including ignition and burnout indices, were analyzed, and the combustion kinetics of the samples were ...

Oxy-fuel fluidized bed combustion of Victorian brown coal .

The bench scale experiments were carried out to evaluate combustion efficiency, agglomeration characteristics, sulphation characteristics, carbonation characteristics, NOX (NO, NO2 and N2O) emission, SOX (SO2 and SO3) emission, and trace elements (Hg, Se, As and Cr) emissions during Oxy-FB combustion of Victorian brown coal.

Experimental Investigation on the Mechanical Behavior of .

Successful hydraulic fracturing depends on the characteristics of the induced fracture network, which controls the enhancement of permeability and ultimate gas production. Among the various factors, the brine concentration in the pore fluid can significantly affect the process, through alterations in microstructure and the impacts of this on rock mechanical behavior.

What is Lignite? - The Balan

According to the Lignite Energy Council, 13.5 percent of lignite coal is gasified into synthetic natural gas and 7.5 percent goes into the production of ammonia-based fertilizers.The balance is used to generate electricity, which provides power for more than 2 million consumers and businesses in the Upper Midwest.
