1.1 Bituminous And Subbituminous Coal Combustion
The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.

Boiler Efficiency - an overview | ScienceDirect Topics
The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

Bituminous coal | coal classification | Britannica
Bituminous coal, also called soft coal, the most abundant form of coal, intermediate in rank between subbituminous coal and anthracite according to the coal classification used in the United States and Canada. In Britain bituminous coal is commonly called “ steam coal,” and in Germany the term Steinkohle (“rock coal”) is used. In the United States and Canada bituminous coal is divided

Boiler Fuels, Emissions and Efficiency - CED Engineering
Bituminous coals are used routinely by electric utilities and in some industrial applications to fire steam-generating boilers even though their sulfur content can be relatively high. Compared to lignitic and subbituminous coals, the heating value of bituminous coals range between 10,500 and 14,000 Btu/lb.

Coal fired domestic steam boilers — Heating Help: The Wall
In looking for a wood-fired steam boiler to replace my 30 yo OIL fired hot water, I was shocked to find that COAL fired steam boilers for domestic use are still being sold in VT & NH. I've been told by salesmen that COAL generates more BTUs, is cheaper than OIL, and can be put in boiler via hopper, just like wood pellets.

Control of Mercury Emissions from Coal-fired Electric
ACI testing was conducted on the 245-MW Unit 1, which fired a low-sulfur bituminous coal with 0.03 ppm Hg and 2000-4000 ppm chlorine. The unit is equipped with low-NOxburners and typically has high levels of unburned carbon (UBC) in the fly ash as indicated by loss on ignition (LOI) measurements.

ORIGIN. The fly ash produced from the burning of pulverized coal in a coal-fired boiler is a fine-grained, powdery particulate material that is carried off in the flue gas and usually collected from the flue gas by means of electrostatic precipitators, baghouses, or mechanical collection devices such as cyclones.

Global Clean Coal Technology Market Share by Type
Since coal is rich in carbon, its combustion leads to the production of energy. Coal is primarily used for electricity and power generation and is categorized into four different types depending on the carbon, oxygen, and hydrogen content present in it. The higher the carbon content, the greater the energy contained by the coal.
