  • How efficient are coal-fired power plants?

  • Figures from the World Coal Association, a keen advocate of HELE, show that the average efficiency of coal-fired power plants around the world today is 33 percent. Modern state-of-the-art plants can achieve rates of 45 percent, while off-the-shelf rates are around 40 percent.

  • How can we reduce emissions from coal-fired power plants?

  • Increasing efficiency and lowering emissions through smarter power plant retrofits and upgrades may be the solution. According to the International Energy Agency, modern coal-fired power plants across the world average 33 percent efficiency.

  • How much more efficient are seawater cooled coal power plants?

  • Using LHV rather than HHV can push up the reported plant efficiency by as much as 10%, depending on the water content of the coal. Finally, seawater or ocean water 鈥?cooled plants have an efficiency advantage over plants that use cooling towers, perhaps as much as 1.5 percentage points.

  • What is the efficiency of a power plant?

  • The efficiencies of these plants range from 35 % to 38 %. Super critical power plants operating at 220 bar and 600/600 C can achieve efficiencies of 42 %. Ultra super critical pressure power plants at 300 bar and 600/600 C can achieve efficiencies in the range of 45% to 48 % efficiency.
