Carbon dioxide
Steam
The type of coal that burns the most efficiently is anthracite coal.
The pollutants produced by burning coal are Mercury-HG Sulphur oxide-SO2 Nitrogen oxides-NO2
Coal burns. The heat boils water. The steam is used to push a turbine. The turbine rotates a generator (its a trick with magnets) that produces the electricity.

The product of this reaction is the sulphur dioxide - SO2.
