Refined coal
Some coal-upgrading processes result in a densified coal product that is considered to be a Black coal equivalent product suitable for burning in black coal boilers. Victorian brown Lignite (derived from Latin lignum meaning 'wood') often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and Lignite

Coal
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.The U.S. Department of Energy's Office of Scientific and Technical InformationBrown coal dust, preparation, handling, and utilization OSTI.GOV

Thermokinetics of Brown Coal during a Fluidized Drying Process
This paper presents the results of research describing the thermokinetics of brown coal’s (lignite) drying process in a fountain-bubble fluidized bed dryer. The drying medium was atmospheric air of a variable temperature in subsequent tests, which ranged from 27 to 70 °C. This paper presents the results of many experimental studies for two Solid-liquid separation in the coal processing circuits is achieved by employing different dewatering equipment such as high-frequency screens, centrifuges, thickeners, and filters. Different aspects of the listed equipment typically utilized in the coal processing circuits are discussed in the subsequent section. 1.3.1 Sizing DevicesMineral Beneficiation and Processing of Coal SpringerLink

Low Rank Coal Upgrading in a Flow of Hot Water Energy & Fuels
Simultaneous hydrothermal degradation and extraction at around 350 °C using flowing solvent as a reaction/extraction medium were proposed for upgrading brown coal, more specifically, for converting brown coal into several fractions having different molecular weight and chemical structure under mild conditions. When an Australian Coal continues to be the backbone of the electricity generation, providing about 38.1% of the world's electricity needs in 2017 [2]. Fig. 2.1 shows the dominance of coal over the next highest fossil fuel and natural gas (23.2%). Other major contributors to the electricity sector include hydroelectricity (15.9%) and nuclear power.Coal: Past, Present, and Future Sustainable Use ScienceDirect

A comprehensive review on hydrogen production from coal gasification
For example, Messerle et al. [7] presented a plasma technology for processing low-quality brown coal sample, and conducted a thermodynamic evaluation and experimental study. In the experiments, they tried to produce syngas including H 2 by using Turgai brown coal in the amount of 100 kg of coal and 41 kg of water vapor.Brown coal: quality is loose, and carbon content is low and softer, and moisture is large, volatile matter high (more than 40%), be the pit coal that degree of coalification is minimum, fixed carbon content is few, poor thermal efficiency, and use value is low, store easy spontaneous combustion, owing to becoming fine powder after the loose weathering of Brown coal dust forming and quality improving method
