Steam is commonly employed in the power industry for coal pulverizer system inerting, due to its ready availability and cost effectiveness. During a ball tube mill start-up, Riley Power Inc. recommends a specified steam flow rate to be introduced and mixed with the primary air entering the mill to establish an inert atmosphere in the mill.

steam pipes to the HP turbine. The high pressure steam arrives from the boiler in pipes wrapped in thick insulation to prevent thermal energy losses. The steam enters the turbine (HP and IP) via emergency stop valves (ESVs) and control valves to regulate the steam flow into the turbine. These valves are hydraulically operated.

Pulverized coal is used in modern thermal power plants. It is a powdered form of coal i.e., coal that is grounded into a dust-like size. The pulverized coal is then conveyed to the furnace by way of a stream of hot air. An important purpose of pulverization is to expose a large surface area to oxygen, thus aiding in the burning process.
