The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38%, with state-of-the-art fossil fuel plants

and power (co-generation). Co-generation produces heat by utilizing the exhaust gas—a lower quality of thermal energy that has a lower temperature and pressure after driving the turbines to generate electricity. Co-generation can achieve a thermal efficiency as high as 80 percent, which is twice that of power generation alone.

Oct 28, 2020 · Energy efficiency of Aerothermal equipment. Aerothermal heat pumps have high performance levels. The maximum COP (Coefficient of Performance) or operating coefficient is around 4 or 5, depending on the manufacturer. This means that for every electric kW-h consumed, Aerothermal equipment can produce 4-5 kW-h thermal in ideal operating conditions.

Thus, the potential for high energy efficiency from an MHD generator. All Brayton cycles have higher potential for efficiency the higher the firing temperature. While a combustion turbine is limited in maximum temperature by the strength of its air/water or steam-cooled rotating airfoils; there are no rotating parts in an open-cycle MHD generator.

Economically, however, the turbine generates power at the efficiency of the steam boiler. The resulting power generation efficiency (modern steam boilers operate at approximately 80% efficiency) is well in excess of the efficiency for state-of-the-art single or combined cycle gas turbines. High efficiency means low electricity generating costs.
