  • How is coal used in a power station?

  • Black or brown coal is pulverised into a powder that鈥檚 burned in a boiler known as a furnace. The heat generated from this turns water fed into the power station into steam which passes through turbines at high pressure. The resulting steam helps move and spin the turbines that are connected to an electrical generator.

  • What is the efficiency of a co-fired power plant?

  • Coal fired power plants operate on the modified Rankine thermodynamic cycle.The efficiency is dictated by the parameters of this thermodynamic cycle. The overall coal plant efficiency ranges from 32 % to 42 %. This is mainly dictated by the Superheat and Reheat steam temperatures and Superheat pressures.
