Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill startup, stopping coal feed on shutdown, or when equip ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal .

Thermal Power Plant. All about Infrastructure Home; Pulverizing Mills. Each of the six units at Drax has ten pulverising fuel mills, each capable of pulverising 36 tonnes of coal per hour. Inside the mills, ten giant hollow steel balls, each tonnes in weight and approximately 730 millimetres in diameter, crush the coal into a fine powder. Crushing the coal into a fine powder makes it ...

 · One limitation is that CO monitoring can only be applied in enclosed spaces, but this makes it ideal for fire detection in equipment such as mills and silos at coal and biomass fired power plants. Another advantage of monitoring carbon monoxide is that it is not normally present in ambient air in significant quantities, whereas early stage combustion creates immediately high levels, so its ...

20/09/2010 · The coal is processed and crushed to increase the efficiency and protect environment. In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm.
