  2. Electric steam boiler - Wikipedia

    en.wikipedia.org/wiki/Electric_steam_boiler

    Electric steam boilers are more efficient than fire-heated boilers because they require less energy to be put into them for operation at capacity. This is because there is little energy lost when the transfer of heat from the heating element to the water occurs, unlike traditional fire heated boilers, where there is a substantial amount of ...

  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 ...

    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 ...

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

    The Cornish boiler developed around 1812 by Richard Trevithick was both stronger and more efficient than the simple boilers which preceded it. It consisted of a cylindrical water tank around 27 feet (8.2 m) long and 7 feet (2.1 m) in diameter, and had a coal fire grate placed at one end of a single cylindrical tube about three feet wide which ...

    The engines are planned to produce electricity in wood chip fired power plants. According to the company, the steam engine named Quadrum generates 27% efficiency and runs with 180 °C steam at 8 bar pressure, while a corresponding steam turbine produces just 15% efficiency, requires steam temperature of 240 °C and pressure of 40 bar. The high ...
