Abstract:

The Queensland coal seam gas industry has grown over the last 12 years. During this time the vast majority of exploration wells have targeted the Late Permian coal measures in the Bowen and Galilee Basins. These formations have been the major target because they contain coals with a vitrinite reflectance ranging above 0.7%. This range has always been seen as the main period for methane generation.As well as containing vast quantities of Permian coal, Queensland also has vast quantities of Middle Jurassic coals within its Mesozoic Basins. These coals have received little-to-no exploration for t

Abstract:

The 1973 decision to base Alberta's electrical generation on sub-bituminous coal has provided a balance between economic, environmental and social goals in the province. Presently six strip mines produce more than 22 million tonnes of low-sulphur coal for 6 thermal stations that generate 90% of the province's electricity needs. Alberta has relatively low-cost power, high coal-related job creation and an industry meeting the goals of sustainable development.

Abstract:

Bituminous coal is an important energy source with significant ripple effects on domestic power generation and industry. However, it is prone to price fluctuations due to climate change and changes in production capacity in major producing countries. In particular, since the outbreak of COVID-19, international prices have skyrocketed due to the closure of mines and port disinfection measures in major producing countries. This study aims to provide an overview of the international bituminous coal market and find insights focusing on recent decarbonization trends and changes in major exporting a

Abstract:

There is considerable development within the coal processing industries of both Indonesia and Australia. Indonesia is rapidly becoming a major coal producer of thermal coal and there is little need for conventional coal preparation of the generally low ash coal. However, much of Indonesia's lower grade coal is high moisture, high volatile sub-bituminous and new methods of thermal moisture reduction and briquetting will have to be used to increase quality, particularly for export. The coal briquetting industry in Indonesia is also planned to grow dramatically to some 4 M tpy to conserve Indones

Abstract:

Since its revitalization in 1968 the Western Canadian bituminous coal industry has operated almost exclusively in export markets. As a result, coal sales have been subject to external demand and pricing forces beyond the control of Canadian companies and governments. The recession that affected all industrialized nations in the early 1980s compounded by the world oil price collapse of 1986 initiated a period of low coal prices, intensified competition among producers and oversupply of internationally traded coal. The attritional effects of this adverse marketing regime became serious for Weste

Eventually coal replaced wood as the primary energy source, and by the 1940s coal provided up to 75 % of US energy. Bituminous coal was the first target of US coal mining.

Abstract:

AbstractTo effectively utilize ventilation air methane (VAM), it is proposed to pass it into the boiler of the coal‐fired power plant for mixed combustion. However, the different types of thermal coal utilized present distinct characteristics when mixed with VAM. In this paper, lignite, bituminous coal, and anthracite are selected to study the CH4 conversion rate, system ignition temperature, and NO emission characteristics of the VAM‐pulverized coal coupled system on a fluidized bed experimental platform. The experimental results show that the ignition temperatures of VAM are 748, 736, and 73

Abstract:

Grindability measurements are widely used in mineral and coal processing industry to determine resistance of materials to comminution.Grindability measurement as testing methods can be divided into two general categories; the Bond and the Hardgrovegrindabilities. Grinding characteristics of the mineral or coal blending have been studied by several researchers over many yearsand a wide range grinding variables has been investigated. In this study, because of the simplicity and the potential usage of themethod for the determination of the grindability of coals and their blending in a comparative

The self-combustion phenomenon that has the potential to cause fires in the coal mining industry in East Kalimantan is the subject of this study. The purpose of this study is to determine the quality and characteristics of coal that has the potential to trigger self-heating. In this research, 5 (five) samples of coal quality are analyzed from PT. Geoservice Samarinda using the proximate analysis method and analysis of calorific value and total sulfur. Next, determine ranking of coal and analyze the characteristics of coal samples that are prone to potential self-combustion. The results show th

Abstract:

AbstractThe expansion of the textile and fashion industries has intensified natural resource consumption and environmental pollution. Consequently, countries with significant textile sectors, such as Türkiye, face substantial challenges in managing textile waste. This study aimed to utilize solid wastes from a textile finishing factory for biochar production. Cotton and cotton/polyester fabric wastes, textile wastewater sludge, and mixed waste (the mixture of all three waste streams) were converted into biochar at different pyrolysis temperatures (300–500 °C). The use of the resulting biochars

Abstract:

Coal is still widely used as the main fuel in the industry, especially the power generation industry (PLTU), cement plants and etc. Coal is a fossil fuel whose availability is thinning and its fires produce CO2 emissions that cause a rise in greenhouse gas (GHG) concentricity. On the other biomass is an alternative energy source that is abundant, including empty bunches of oil palm (TKKS), but has poor combustion properties compared to coal when burned directly. The properties of biomass burning can be improved by certain treatment, one of which is through the process of torrefaction. Biomass

Abstract:

Electric arc furnace dust (EAFD) is a significant secondary resource harbouring valuable metallic constituents like zinc, iron and at the same time, it is also a hazardous material as it releases toxic heavy metals like cadmium, lead and chromium to the environment. One potential way to utilise EAFD is to reduce it in the form of self-reducing EAFD–coal composite pellet and subsequently charge it to blast furnace for iron recovery while heavy metal will pass through slag to the cement industry. This investigation reports the reduction behaviour of EAFD–coal composite pellets in tube furnaces a

AbstractThe cement industry is one of those that consumes the most energy, due to the high temperatures required to produce this material, and it is also one of the most that generates high CO2 emissions. In this work, the addition of sugarcane ash, bituminous coal and hazardous residues in cement pastes were evaluated. For this, cement pastes were produced in accordance with ASTM C305, from which the test specimens were prepared to analyze compressive strength and parallel to this, metal leaching tests were performed using the SPLP procedure. Following this, the reactivity of the fly ash in t

AbstractFly ash is currently a problem in different companies, mainly in thermoelectric plants, which must follow a production and consumption model that involves reusing, renewing, and recycling, thus contributing to the circular economy. This work aims to evaluate the reactivity and compressive strength of different types of ashes in concrete monoliths. For this purpose, sugarcane bagasse (SCBA), bituminous coal (BC), and untreated hazardous waste (RUD) were evaluated as replacements for cement.

In this study, the data obtained from the results of laboratory tests are the value of Moisture Content, Volatile Matter, and HGI values, these three data are indicated to be related/related to each other in determining coal rank, for this reason, a data correlation test was carried out. The calorific value of the coal sample that has been tested is 5,837 cal/gr or 10,506.6 BTU/lb when referring to the ASTM D 388–12 standard. The calorific value of this coal sample indicates that the coal sample tested can be cla
