The HAT, StiG and LOTHECO Cycles
HAT stands
for a Humid Air Turbine. StiG stands
for Steam injected Gas turbine.
These cycles are alternates to combined cycle power plants which need investment
in order to set up bottoming cycles (Steam Cycle). Their efficiency is somewhat
lower (44%) compared to the 45-50% expected from combined cycle plants. The Lotheco
power plant, however, involves the usage of low quality heat in order to
enhance the heat productivity. Ultimately, it effects the LCE (cost of
electricity).
