2. Reboiler - Wikipedia

   en.wikipedia.org/wiki/Reboiler

   Fired heaters (Image 3), also known as furnaces, may be used as a distillation column reboiler. A pump is required to circulate the column bottoms through the heat transfer tubes in the furnace's convection and radiant sections. The heat source for the fired heater reboiler may be either fuel gas or fuel oil.

3. Fume hood - Wikipedia

   en.wikipedia.org/wiki/Fume_hood

   A downward air flow is generated and hazardous vapors are collected through slits in the work surface. Downflow fume hoods are encountered more frequently in applications involving powders, [54] and are comparable to laminar flow cabinets. The laminar flow within these devices is easily disrupted, more so than traditional fume hoods, which can ...

   A typical evaporative, forced draft open-loop cooling tower rejecting heat from the condenser water loop of an industrial chiller unit Natural draft wet cooling hyperboloid towers at Didcot Power Station (UK) Forced draft wet cooling towers (height: 34 meters) and natural draft wet cooling tower (height: 122 meters) in Westphalia, Germany Natural draft wet cooling tower in Dresden (Germany)

5. Furnace (central heating) - Wikipedia

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

   These furnaces were still big and bulky compared to modern furnaces, and had heavy-steel exteriors with bolt-on removable panels. Energy efficiency would range anywhere from just over 50% to upward of 65% AFUE. This style furnace still used large, masonry or brick chimneys for flues and was eventually designed to accommodate air-conditioning ...

6. Industrial furnace - Wikipedia

   en.wikipedia.org/wiki/Industrial_furnace

   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] They are used to provide heat for a process or can serve as reactor which provides heats of reaction.

7. Water-tube boiler - Wikipedia

   en.wikipedia.org/wiki/Water-tube_boiler

   These tubes, especially the central set, have sharp curves. Apart from obvious difficulties in cleaning them, this may also give rise to bending forces as the tubes warm up, tending to pull them loose from the tubeplate and creating a leak. There are two furnaces, venting into a common exhaust, giving the boiler a wide base tapering profile. [14]
