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.

Fire and Explosion Prevention in Coal Pulverizing Systems

2018-2-1  In practice, the more dangerous condition is an ignition source, i.e., a fire, within the coal pulverizing or conveying equipment. Fires are generally caused by accumulations of powdered coal brought to temperatures above their ignition temperature, either by hot air flowing over the deposit or by the deposit laying out on a hot surface.

Pulverizers 101: Part II POWER Magazine

2011-10-1  Pulverizer “capacity” is the amount of coal a pulverizer can grind at a given raw feed rate, to a given fineness, at a certain Hardgrove Grindabilty Index (HGI), and at a specific raw fuel

Coal Pulverizer Explosions ASTM International

Ignition events that remained within the coal pipe created only weak pressure rise, while ignition events within the simulated pulverizer volume created explosions exceeding 70 bars (7000 kPa). These experiments showed that explosion characteristics depend on dust concentration, ration of pulverizer volume to coal pipe area, as well as coal type.

Pulverizer Fire and Explosions

Fundamental precautionary methods to reduce the chance of a pulverizer “puff” is to ensure the following: Pulverizer airflow is adequate to facilitate stable transport of coal without settling in the burner line (>3,500 Fpm) but not excessively high to provide an abundant source of air for combustion in the presence of an ignition source.
