A pulverized coalfired 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.

Activated charcoal is a fine, odorless, black powder. It is produced by heating charcoal to an extremely high temperature in an environment without oxygen, such as a tank. Once activated, the powder's pores trap chemicals, making it effective at treating overdoses and chemical poisonings by preventing the body from absorbing the toxic substances.

Powder and lumps of the Argonne Premium Upper Freeport coal were compared in a 9monthlong CO2 sorption−desorption study. On the basis of the slope analysis, CO2 induced the lumps swelling by 7%. The powder swelled by 8% and then rapidly shrank by 3% on desorption. This was verified by a "single point" injection of helium and the pressureanddensity technique, which was sufficiently ...
