Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Catalog of CHP Technologies, Section 4. Technology

district heating systems where adding a steam turbine between the boiler and the distribution system or placing a steam turbine as a replacement for a pressure reducing station may be an attractive application. Often the boiler is capable of producing moderate -pressure steam but the distribution system needs only low pressure steam.

Cracking (chemistry) - Wikipedia

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts.

Radiator Heaters: Your Guide to Old-Fashioned Heat

Dec 17, 2013 · This mineral oil, more aptly referred to as thermal oil or heat transfer oil, is not burned in the process of heating, so it does not need refilling or replacement. It has an uncannily high boiling point and specific heat capacity, which allows small volumes of the oil to emit remarkably high quantities of thermal energy without
