What You Should Know About Metallurgical CoalDiese Seite übersetzen

Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker and contains more carbon and less moisture and ash than low-rank coals.

Oxy-fuel conversion of sub-bituminous coal .Diese Seite übersetzen

Oxy-fuel combustion in pulverized coal (PC) and fluidized bed (FB) boilers is being increasingly investigated due to its potential use for carbon dioxide capture. The combustion conditions in the two types of unit differ significantly because of fuel size, furnace temperature, and fluid dynamics. These differences affect the change of combustion characteristics from air (O2/N2)to oxy-fuel (O2 ...

Torrefied biomass has several benefits, such as higher energy density, good grindability, higher flowability and uniformity. The process of torrefaction moves the chemical and physical properties of raw biomass close to that of bituminous coal, which allows co-utilization with high substitution ratios of biomass in the existing coal-fired boilers without major modifications.

Bituminous coal - WikipediaDiese Seite übersetzen

Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60–80%; the rest is composed of water, air, hydrogen, and sulfur, which have not been driven off from the ...

Why Pulverized Coal is Used in a Power Plant

There is one important characteristic of coal that decides the type, size, and power required for pulverizing. This is the grindability of coal and is denoted by the Hardgrove Grindability Index (or HGI). Grindability in general is a function of the grade of coal. Sub-bituminous coal from the Indian sub-continent has an index near fifty. A ...

What are the types of coal?

Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous usually has a high heating (Btu) value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.
