EFFECT OF BULK DENSITY OF COAL BLEND ON THE CALORIFIC VALUE OF COKE

open access: yesJournal of Coal Chemistry, 2020
The article is devoted to laboratory studies to determine the influence of the bulk density of a coal blend (in particular, tamped) on the value of the gross calorific value of the coke obtained from it. To making up a model coal blends, coal concentrates has been selected and analyzed from the raw material base of Ukrainian coke enterprises.

Quantity over quality? Prey-field characteristics influence the foraging decisions of little penguins (Eudyptula minor)

open access: yesRoyal Society Open Science, 2022
Quantifying prey characteristics is important for understanding the foraging behaviour of predators, which ultimately influence the structure and function of entire ecosystems. However, information available on prey is often at magnitudes which cannot be

Impact of torrefaction technique on the moisture contents, bulk density and calorific value of briquetted biomass [PDF]

open access: yesPolish Journal of Chemical Technology, 2015
Abstract The concept of different compositional biomass is introduced to enhance the binding properties and utilize the use of different seasonal biomasses. The effect of densification on the heating values of single pure and mixed compositional biomasses is observed with and without applying special type of pretreatment named as ...

Extractives and energetic properties of wood and charcoal

open access: yesRevista Árvore, 2014
Charcoal production stands out as a raw material for the production of renewable energy. To assess wood quality in energy terms, studies have focused more on the holocellulose and lignin content than on the role of extractives.
