Moisture readsorption and low temperature oxidation

Low rank coal sees little use in spite of its large reserves and low price because it has high moisture content and low heating value. However, the recent high price of oil and high rank coal has encouraged many industries to use low rank coal. Upgraded brown coal (UBC), a well-known coal drying process, enables the utilization of low rank coals.

Jun 15, 2009Low-grade coals are usually those that are low in specific energy because of high moisture content and/or ash content or produce high emissions of concern. These are commonly lignites or sub-bituminous coals. There is a growing need of using these low-grade coals because of higher quest for power generation. In general, the direct use of the low-grade coals results in higher costs of

Evaluation of the effect of a palm acid oil coating on

Indonesian low rank coal (LRC) was upgraded by the addition of palm acid oil (PAO), and the efficiency of the inhibition of spontaneous combustion, as well as the resistance to moisture readsorption, was compared with raw coal. Fluorescence microscopy images revealed that PAO was well distributed in the coal matrix during the drying process.

What is Coking Coal

Coke quality is largely influenced by coal rank, composition, mineral content and the ability to soften when heated, become plastic, and resolidify into a coherent mass. Bituminous class coals of high, medium, and low volatile rank that possess these properties are called "coking" coals.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Lignite is the lowest rank of coal. It is a peat that has been transformed into a rock, and that rock is a brown-black coal. Lignite sometimes contains recognizable plant structures. By definition it has a heating value of less than 8300 British Thermal Units per pound on a mineral-matter-free basis.

istics of the coal, indigenous or imported, consumed in the respective countries. By virtue of the specifics of the coal formation process, the US, Canadian and European coal, for example, is high in sulphur, but relatively low in nitrogen. In case of India, it is just the other way. Coal

Change of combustion characteristics of Indonesian low

Upgraded brown coal (UBC) process has been developed to produce a dry upgraded coal which is comparable with a bituminous coal. Differential thermal and thermogravimetry analyses (DTA–TG) have been applied to study the combustion characteristics of some Indonesian raw and upgraded coals produced by the UBC process.

The direct process has not yet been commercially proven, but potentially provides a lower cost path with fewer steps and associated technologies. It involves dissolving the coal in a solvent at high temperature and pressure, followed by hydrogenation (adding hydrogen)

Chapter 7 COAL

Chapter 7 COAL If we as a nation are to benefit in the future from our enormous, low-cost coal reserves, a variety of efforts are necessary to (1) develop and demonstrate new "clean coal" technologies; (2) reduce uncertainty over environmental regulation and allow electric power

SPONTANEOUS COMBUSTION IN COAL

1. Storing coal with low sulphur content is helpful. Sulphur compounds in coal liberate considerable heat as they oxidize. 2. Air circulating within a coal pile should be restricted as it contributes to heating; compacting helps seal air out. 3. Moisture in coal contributes to spontaneous heating because it assists the oxidation process.

Lignite

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It is considered the lowest rank of coal due to its relatively low heat content.It has a carbon content around 60–70 percent. It is mined all around the world, is used almost exclusively as a fuel for steam-electric power generation, and is the coal which is most
