2. Boiler (power generation) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(power_generation)

   His boilers worked at 40–50 psi (276–345 kPa) and were at first of hemispherical then cylindrical form. From 1804 onwards Trevithick produced a small two-pass or return flue boiler for semi-portable and locomotive engines.

3. Annual fuel utilization efficiency - Wikipedia

   en.wikipedia.org/wiki/Annual_fuel_utilization...

   The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...

4. Supercritical steam generator - Wikipedia

   en.wikipedia.org/wiki/Supercritical_steam_generator

   Ultra-supercritical – up to 1,400 °F (760 °C) and pressure levels of 5,000 psi (340 bar) (additional innovations, not specified, would allow even more efficiency) Nuclear power plant steam typically enters turbines at subcritical values – for U-Tube Steam Generators 77 bar (1,117 psi) and 294 °C (561 °F), with comparable temperature and ...

   The water-tube boilers of the monotube type used in steam cars, such as: AMC; Clayton Steam Generator; Doble steam car; Gardner-Serpollet; Locomobile Company of America; White Motor Company, US patent 659,837 of 1900 [5]

6. Combustion Engineering - Wikipedia

   The basis for this increase in efficiency was a computer-based system called the Core Operating Limit Supervisory System (COLSS) for design, and the Core Protection Calculator (CPC) for real-time control room operation, [10] which leveraged almost 300 in-core neutron detectors and a patented algorithm to allow higher power densities.

7. Thermal efficiency - Wikipedia

   en.wikipedia.org/wiki/Thermal_efficiency

   For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the coefficient of performance or COP) is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is ...
