Coal is combusted in a steam boiler. The specific coal contains 25 MJ/kg
If the boiler is 90% efficient, how much coal must be burned per hour to produce a stream thermal gain of 665 MJ/s.
Roughly how much CO2 will be produced by this boiler?
The solution contains the calculations for the production of energy by coal. Efficiency of the boiler is given and how much coal needed to provide steam energy is calculated.
