    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.

  3. Delayed coker - Wikipedia

    en.wikipedia.org/wiki/Delayed_coker

    A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke. [1] [2] [3]

  9. 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.
