Pulverizer Fire and Explosions

Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial. Hot smoldering or burner raw fuel anywhere in the pulverizer system is considered serious. Raw coal that is allowed to "spill" into the under bowl (air inlet) section and is allowed to accumulate will be exposed to high temperature (usually ...

Fire Detection Methods for Coal Pulverizer ... - Babcock Power

The studies showed that there is an emergence of low rank, high reactive coals as a base fuel for power plants which is resulting in an increase in pulverizer system fires. Also, the EPRI study concluded that reducing the frequency of fires would reduce the risk of coal dust explosions. Unfor- tunately, less than 15 percent of the power plants have adequate fire detection systems for coal ...

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.
