Goal may be fired as a finely powdered fuel that is injected into the furnace The coal is pulverized to a fineness of 70 per cent or more through a 200 mesh sieve It is then transported by hot primary air which also dries the coal to the furnace The majority of all central steam generators operating at 200 000 lb steam per hr and over are

Pulverised Coal Combustion an overview ScienceDirect Topics

Pulverized Coal Combustion PCC technology is a widely utilized technology to generate energy from fossil fuel especially coal [15] In this technology pulverized coal is injected to combust in a furnace in the presence of a controlled level of air The heat generated is used to produce high pressure steam driving a steam turbine to generate electrical power The

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
