2. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   At the furnace, cool air passes into the furnace, usually through an air filter, through the blower, then through the heat exchanger of the furnace, whence it is blown throughout the building. One major advantage of this type of system is that it also enables easy installation of central air conditioning , simply by adding a cooling coil at the ...

3. Forced-air gas - Wikipedia

   en.wikipedia.org/wiki/Forced-air_gas

   Older furnaces sometimes relied on gravity instead of a blower to circulate air. [1]Gas-fired forced-air furnaces have a burner in the furnace fueled by natural gas.A blower forces cold air through a heat exchanger and then through duct-work that distributes the hot air through the building. [2]

4. Soot blower - Wikipedia

   Air Heater Blower; Rotating Element Sootblowers; Multi-Media Sootblowers; Fixed Rotating; Steam blowing medium: Steam; Air; High Pressure Water; Dual-media air heater; Steam is normally used as a medium for blowing away the soot since capital cost of steam pressure reducing equipment and drain is less than the cost of compressors, motors and ...

5. Industrial furnace - Wikipedia

   en.wikipedia.org/wiki/Industrial_furnace

   An industrial chamber furnace, used to heat steel billets for open-die forging. An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1]

6. Open-hearth furnace - Wikipedia

   en.wikipedia.org/wiki/Open-hearth_furnace

   Tapping open hearth furnace, Fagersta steelmill, Sweden, 1967. Carl Wilhelm Siemens developed the Siemens regenerative furnace in the 1850s, and claimed in 1857 to be recovering enough heat to save 70–80% of the fuel. This furnace operates at a high temperature by using regenerative preheating of fuel and air for combustion. In regenerative ...

7. Blowing engine - Wikipedia

   en.wikipedia.org/wiki/Blowing_engine

   As blast furnaces re-equipped after World War II, the favoured power source was either the diesel engine or the electric motor. These both had a rotary output, which worked well with contemporary developments in centrifugal fans capable of handling the huge volumes of air. Although the reciprocating steam blowing engine continued where it was ...
