Integrated gasification combined cycle - Wikipedia
An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the power generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process.

Pulverized coal-fired boiler - Wikipedia
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Coal Mine Safety Dust - Carmeuse
Milled limestone, referred to as "rock dust" by the coal industry, is an additive used for safety in underground bituminous coal mines. The particles of the milled limestone mix with coal dust to prevent a potential explosion. Rock dust is blown or sprayed (as a slurry) onto the roof, ribs and floor of the mine, and needs to be re-applied on a regular basis to maintain its effectiveness.
Coal power technologies - SourceWatch
Integrated gasification combined cycle (IGCC) plants use a two-step process to create electricity. In the first step, coal is converted into synthetic gas or syngas. In the second step, the gas is used to power a steam turbine, with waste heat from the turbine being recovered to provide additional power (hence the term "combined cycle").
