A single unit of coal (4MJ) fed into a boiler and then utilised in a steam engine will result in 4MJ of energy added to an electrical system. It costs 30kJ energy to heat 1 unit of water to steam at 165°C, so one boiler will produce 60 steam per second.
With lower furnace pressure drop, the power consumption of air fans can be reduced, whereas the comminution energy consumption of coal particles will be increased. To optimize the auxiliary power consumption, the balance point between the power consumption of air fans and that of the coal comminution should be investigated.
