  2. Space heater - Wikipedia

    en.wikipedia.org/wiki/Space_heater

    Combustion space heaters convert chemical energy into heat through combustion of a fuel. These heaters often do not require electricity to function and can therefore be used off-the-grid. Honeywell electric infrared radiant heater Sunbeam quartz space heater uses quartz tubing for infrared heating

  3. Spacecraft thermal control - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_thermal_control

    For a spacecraft the main environmental interactions are the energy coming from the Sun and the heat radiated to deep space. Other parameters also influence the thermal control system design such as the spacecraft's altitude, orbit, attitude stabilization, and spacecraft shape. Different types of orbit, such as low Earth orbit and geostationary ...

  4. Shell-and-tube heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

    A shell-and-tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...

  5. External Active Thermal Control System - Wikipedia

    en.wikipedia.org/wiki/External_Active_Thermal...

    The International Space Station (ISS) External Active Thermal Control System (EATCS) [1] maintains an equilibrium when the ISS environment or heat loads exceed the capabilities of the Passive Thermal Control System (PTCS). Note Elements of the PTCS are external surface materials, insulation such as Multi-Layer Insulation (MLI), or Heat Pipes.

  6. Rocket mass heater - Wikipedia

    en.wikipedia.org/wiki/Rocket_mass_heater

    In a rocket mass heater, by-products of combustion, such as smoke, soot, and creosote compounds, are sucked into the insulated tunnel of the unit, where some [who?] claim they further combust, releasing even more heat energy to drive the rocket process, unlike a normal fire, where they are blown out the chimney. [5]

    Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters, each year from 2016 to 2020, per the NFPA.

  8. Thermal efficiency - Wikipedia

    en.wikipedia.org/wiki/Thermal_efficiency

    Heat pumps, refrigerators and air conditioners use work to move heat from a colder to a warmer place, so their function is the opposite of a heat engine. The work energy (W in) that is applied to them is converted into heat, and the sum of this energy and the heat energy that is taken up from the cold reservoir (Q C) is equal to the magnitude ...

  9. Air preheater - Wikipedia

    en.wikipedia.org/wiki/Air_preheater

    The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney ) at a lower temperature, allowing simplified design of the conveyance system ...
