Generating Electricity from Coal

Here's how the process works 1 Heat is created Before the coal is burned it is pulverized to the fineness of talcum powder It is then mixed with hot air and blown into the firebox of the boiler Burning in suspension the coal/air mixture provides the most complete combustion and maximum heat possible 2 Water turns to steamGet price
