How do coal power plants ignite the pulverized .Traduire cette page

The coal is crushed to a powder, then blasted into a furnace where it burns to heat water to produce steam. What I am curious about, is what sort of ignition system is needed to burn the pulverized coal? Is there a gas burner used during startup to light the coal and then it burns on its own? Does an oil or gas burner run continuously to ignite the coal? Does someone just throw in a match?

Pulverised Coal - an overview | ScienceDirect Topics

A coal-fired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9.After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

Coal mill pulverizer in thermal power plants

2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner panels.
