Decrease of Calorific Value and Particle Size in Coal Stockpiles
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008Abstract During storage of excess amount of coal, they lose both their economical value and cause environmental problems. In this work, two industrial-sized stockpiles were constituted at a coal stockyard of Western Lignite Corporation (WLC) in Tuncbilek, Turkey.

Forecast of the gross calorific value of coking coals
Solid Fuel Chemistry, 2017The comprehensive analysis of 63 test samples of coal concentrates from Ukraine, the Russian Federation, and countries outside the former Soviet Union (the United States, Canada, Australia, and Poland), which constitute the current raw materials base of the by-product coke plants of Ukraine, was carried out.

Calorific Value of Coke. 3. Influence of Coal Storage
Coke and Chemistry, 2019Abstract—The possibility of increasing the calorific value of coke from oxidized coal is established experimentally and confirmed theoretically. This entails the use of measures already developed for the rational use of oxidized coal in coking—in particular, with a view to ensuring the required coke quality.

Determination of calorific values of coals by differential thermal analysis
Fuel, 1992Abstract This paper examines a further use for the thermal analysis technique in the coal science field. Eight Spanish coal samples, of different origin and rank, and their corresponding chars have been studied. The applicability of differential thermal analysis (DTA) for determining the calorific values of coals has been tested after analysing its ...

Determination of Uncertainty in Gross Calorific Value of Coal Using Bomb Calorimeter
International Journal of Measurement Technologies and Instrumentation Engineering, 2011A bomb calorimeter is an apparatus used for measuring the performance of coal in term of heat of combustion. Recent awareness has been created regarding uncertainty of measurement, due to mainly two reasons. Laboratory accreditation, which has steadily been on the rise, which requires a estimation of uncertainty of measurement particularly in the field

Methods of Increasing the Calorific Value of Fine Coal Waste
2016The most frequent solution of water-slime industry in mines and companies working on coal output enrichment is linking watercourses from individual technological nodes into one stream of water-slime slurry. The outcome of such solutions is water-slime mixture of averaged composition and physicochemical properties.
