How Does a Coal Power Plant Work? - Bright Hub
Around 2 million tons of coal will be required each year to produce the continuous power. Coal combustion in the boiler requires air. Around 1.6 million cubic meter of air in an hour is delivered by air fans into the furnace. The ash produced from this combustion is around 200,000 tons per year. Electrostatic precipitators capture almost all of this ash without dispersing this to the ...
How is Steel Produced? World Coal Association
Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process. A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal. This method has a number of advantages, including reducing overall costs and ...

Coal-Fired Industrial Boiler Inspection Guide
About 15 to 20 percent of the air required for combustion is used to transport the coal to the burner. This air, known as primary air, also dries the coal in the pulverizer. The remaining 80 to 85 percent of the combustion air, known as secondary air, is introduced at the burner. Figure 11 shows a typical pulverized-coal-fired boiler. The two basic components of a pulverized-coal system are: 0 ...
