Pulverised Coal Combustion - an overview | ScienceDirect ...

5.05.3.1 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 ...

CHAPTER THREE Coal-Fired Power Plant Designs,

coal in EGUs. The current dominant design is a pulverized-coal (PC) unit, in which coal is ground via a pulverizer to a fine powder and then combusted in a burner. 1 PC units are the most prevalent technology in the coal EGU fleet and represent about two-thirds of the current units progressing and under construction (Shuster, 2011). An alternative
