Advanced supercritical coal fuel
This article examines the role, distribution, economics and industrial importance of coal used for advanced supercritical and ultra‑supercritical power plants — commonly referred to here as advanced supercritical coal fuel.…
Oxyfuel-grade coal
This article examines the properties, occurrence, extraction, economic role and industrial importance of oxyfuel-grade coal — coal types most suitable for combustion in an oxyfuel environment aimed at facilitating post-combustion…
Coal for circulating fluidized bed
Circulating fluidized bed (CFB) boilers have become an important technology for burning a wide variety of fuels, especially lower-quality coals that are abundant but challenging for conventional combustion systems. This…
CFB-grade coal
This article examines CFB-grade coal—a category of solid fuel optimized for use in circulating fluidized bed combustion systems—and explores where it occurs, how and where it is mined, its economic…
FBC-grade coal
This article examines FBC-grade coal in depth: what it is, its characteristic properties, where it is found and mined, how it is used in industry, and the economic and environmental…
Coal for fluidized-bed combustion
This article examines coal used specifically for fluidized-bed combustion (FBC) — a versatile coal-combustion technology well suited to a wide range of fuels, especially low-grade coals. We will describe the…
SO₂-reducing coal
The coal industry has long been associated with high emissions of sulfur dioxide (SO₂), a major contributor to acid rain, respiratory illness, and environmental degradation. Over the past decades, the…
Emission-reduction coal
This article explores the concept commonly called emission-reduction coal — coal that is managed, processed or combined with technologies and practices to produce lower greenhouse-gas and pollutant emissions than conventional…
Reburning coal
This article examines the coal commonly associated with the phrase “Reburning coal” — both as a combustible fuel and in the context of reburning technologies used in coal-fired power generation.…
Kiln-fired coal
Kiln-fired coal occupies a distinct place within the broad family of solid fossil fuels and processed carbon products. Although the term can refer to several different processes and products, it…
