Flanged Heaters - Wattco Inc.

Flanged heaters are commonly used in many chemical, petroleum and water based applications. Consisting normally of an ANSI rated flange with several hairpin elements or bugle tubular elements extending from the face of the flange, this electric heater uses direct heat application to the liquid medium. A thermowell is often used within the bundle of elements to allow for a probe (either a

Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 5.3.3 Economizers. Economizers are one of the four main heat transfer surface types. The name economizer comes from German Ekonomizierung (to economize). They were first used in shell and tube boilers to preheat the feedwater. Feedwater preheating helps to capture more heat from the flue gases.

Hot-bulb engine - Wikipedia

The hot-bulb engine is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb chamber by the rising piston. There is some ignition when the fuel is introduced, but it quickly uses up the available oxygen in the bulb.
