donkey boiler: A donkey boiler is used to supply non-essential steam to a ship for 'hotel' services such as heating or lighting when the main boilers are not in steam, for example, when in port. [3] Donkey boilers were also used by the last sailing ships for working winches and anchor capstans. See also auxiliary boiler. du Temple boiler: An ...
By comparison, most modern "warm air" furnaces typically use a fan to circulate air to the rooms of house and pull cooler air back to the furnace for reheating; this is called forced-air heat. Because the fan easily overcomes the resistance of the ductwork, the arrangement of ducts can be far more flexible than the octopus of old.
This is the operational rating for this building. The rating shows the energy performance of the building as it is being used by the occupants, when compared to the performance of other buildings of the same type. A building with performance equal to one typical of its type would therefore have an Operational Rating of 100.
Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation. The temperature or condition of steam required for ...
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil.

From Brown Boveri Review [3]. The Velox principle combines the use of combustion under pressure, with very high flue gas velocities and with a gas turbine, whereby the pressure in the combustion chamber, the high gas velocities and the pressure drop of the gases for production of work are created by means of a compressor driven by the gas turbine, the latter being actuated by the products of ...
