Review of solutions to global warming, air pollution, and
The addition of CCS equipment to a coal power plant results in an additional 14–25% energy requirement for coalbased integrated gasification combined cycle (IGCC) systems and 24–40% for supercritical pulverized coal plants with current technology. 32 Most of the additional energy is needed to compress and purify CO 2.

Glossary
Pulverized coal is a coal that has been crushed to a fine dust in a grinding mill. It is blown into the combustion zone of a furnace and burns very rapidly and efficiently. Slack coal usually refers to bituminous coal onehalf inch or smaller in size.

Study on the migration of pulverized coal in CBM wellbore
A method using multifluid Eulerian computational fluid dynamics (CFD) model to study the migration of pulverized coal in coalbed methane (CBM) wellbore is presented in this paper. The study aims to predict the condition of discharging pulverized coal out of CBM wellbore and decrease downhole failures such as low efficiency, pump leakage and stuck pump caused by the deposition of pulverized coal.

Advanced Pulverized Coal Injection Technology and Blast
Oct 11, 2000In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column. The capacity of the furnace to consume these particles by solution loss is probably one
