  2. Boiler (power generation) - Wikipedia

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

    L.D. Porta gives the following equation determining the efficiency of a steam locomotive, applicable to steam engines of all kinds: power (kW) = steam Production (kg h −1)/Specific steam consumption (kg/kW h). A greater quantity of steam can be generated from a given quantity of water by superheating it.

  3. Feedwater heater - Wikipedia

    en.wikipedia.org/wiki/Feedwater_heater

    A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...

  4. Power-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Power-to-weight_ratio

    A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.

  5. Thermal energy storage - Wikipedia

    en.wikipedia.org/wiki/Thermal_energy_storage

    A working fluid, typically water or steam, is used to transfer the heat into and out of the system. Thermal conductivity of miscibility gap alloys is often higher (up to 400 W/(m⋅K)) than competing technologies [37] which means quicker "charge" and "discharge" of the thermal storage is possible. The technology has not yet been implemented on ...

  6. Ton of refrigeration - Wikipedia

    en.wikipedia.org/wiki/Ton_of_refrigeration

    It was originally defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. [1] [2] The modern definition is exactly 12,000 Btu IT /h (3.516853 kW). Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of ...

  7. Electric steam boiler - Wikipedia

    en.wikipedia.org/wiki/Electric_steam_boiler

    Water from the system or holding tank is then run over or near this hot element in a pipe or tank, heating the water to a suitable temperature, then making the water hot enough to boil and become saturated steam, [1] at which point the saturated steam is transported to wherever it is needed via the steam pipes that exit the body of the electric ...

  8. Thermal power station - Wikipedia

    en.wikipedia.org/wiki/Thermal_power_station

    A central battery system consisting of lead–acid cell units is provided to supply emergency electric power, when needed, to essential items such as the power station's control systems, communication systems, generator hydrogen seal system, turbine lube oil pumps, and emergency lighting. This is essential for a safe, damage-free shutdown of ...

  9. Combined cycle power plant - Wikipedia

    en.wikipedia.org/wiki/Combined_cycle_power_plant

    Heat transfer from hot gases to water and steam. The steam power plant takes its input heat from the high temperature exhaust gases from a gas turbine power plant. [5] The steam thus generated can be used to drive a steam turbine. The Waste Heat Recovery Boiler (WHRB) has 3 sections: Economiser, evaporator and superheater.
