Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, 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 ...
Table 3.1 demonstrates the range of mean moisture contents in the commercially exploited brown coal deposits in Victoria, expressed on both a wet basis (% moisture in total weight of moist coal) and relative to the dry coal (kg of water/kg of dry coal substance). It is important to note that whereas these moisture contents vary over a …

The cation exchange properties of Australian brown coals were investigated aiming at clarifying the influence of surface treatments. Dry heat treated (100–300°C, 2 h) and hydrothermally treated (130–300°C, 1 h) samples were used. Ion exchange experiments were performed by soaking coals in the solutions of calcium, magnesium, …
Brown coal basics. Victoria's lignite is typically low in ash, sulphur, heavy metals and nitrogen. However, its high moisture content - which ranges from 48-70 per cent - reduces its effective energy content (average 8.6 MJ/kg on a net wet basis or 26.6 MJ/kg on a gross dry basis).

Utilisation of brown coal in slagging gasification technologies requires a detailed assessment of coal ash chemistry in terms of potential slagging behaviour. We investigated the phase compositions of four categories of brown coal ashes and synthetic slags after processing at 900–1100 °C and 1200–1600 °C, respectively, under reducing ...
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 term brown coal is used to describe those low-rank coals (lignite and subbituminous ...
It also estimates that Australia has approximately 70 billion tonnes of economically demonstrated resources of black coal and 76 billion tonnes of brown coal or lignite [47, p. 11]. At current production rates these resources would sustain production of black coal for 125 years and brown coal for over 1,200 years [45].

Sub-Bituminous Coal Sub-bituminous coal is about 100 million years old. It contains more carbon than lignite, about 35-45 percent. In many parts of the world, sub-bituminous coal is considered "brown coal," along with lignite. Like lignite, sub-bituminous coal is mainly used as fuel for generating electricity.
Processing in Australia might reduce shipping volumes and transport costs, but will likely incur a carbon cost. In 1899, the Great Morwell Coal Mining Company went broke due to competition from ...
Victorian brown coal is a cost effective fuel for power generation. It is very cheap to mine and low in sulphur and ash yield but the high moisture content and hence low calorific value result in high CO 2 emission intensity relative to bituminous coal. This high moisture has ensured that power stations are located adjacent to their mines to minimise handling, …
About 430 billion tonnes of brown coal reserve is located in Victoria. Eighty percent lies in the Gippsland Basin. Brown coal is made up of partially decayed plant …
Under the $500m Hydrogen Energy Supply Chain (HESC) pilot project, hydrogen will be made in Victoria's LaTrobe valley from brown coal and transported aboard a purpose-built ship to Japan, where ...
ECT has developed the Coldry process for the removal of water from brown coal, and says it uses heat to dry the coal to between 10 and 14 per cent. Environmental …
Bringing coal to light. The Latrobe valley is rich in one of Victoria's most important resources: lignite, or brown coal as it's commonly known. This coal is responsible for 85% of the electricity in Victoria, and also supplies electricity to Tasmania and New South Wales. The Yallourn mine is the oldest in Victoria, and Australia's second-largest open cut mine.
The difference spectra indicate that the drying of as-received coal at room temperature using a Super Absorbent Polymer (SAP) removes only 44% of moisture compared to oven drying at 105 °C. As the SAP does not completely remove the water from the coal the possibility of explosion due to oxidation of the coal powder is greatly reduced.

The Australian resources of brown coal are estimated at over 400 billion tonnes. The current economic downturn and low prices on thermal and metallurgical coal, as well as low oil prices, may delay the development of some lignite projects and, most importantly, the development of lignite processing technologies.
Victorian brown coals represent one of the purest and most extensive concentrations of organic matter anywhere in the world with ash yields generally less than 2%. These coals typically contain 69.6% carbon, 5.0% hydrogen, 24.6% oxygen, 0.5% nitrogen, and 0.3% sulfur on a dry mineral and nonmineral-inorganic free basis.

The Latrobe Valley in Victoria, Australia has the largest brown coal deposit in the world, where large-scale brown coal mines were established in the early 1970s. The geotechnical stability of mining batters requires a comprehensive understanding of the mechanical behavior of the brown coal. Therefore, an experimental study was undertaken to ...
The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 …
Coal refers to all coal and brown coal, both primary (including hard coal and lignite-brown coal) and derived fuels (including patent fuel, coke oven coke, gas coke, coke oven gas, and blast furnace gas). Peat is also included in this category. Australia coal usage/consumption for 2015 was 62.87%, a 1.71% increase from 2014.
Last Friday, the Victorian and federal governments announced a $90 million fund to develop brown coal processing technology in the Latrobe Valley. The fund is called the Advanced Lignite …
