Hot gas mantles. The lowest visible mantle has partially broken, reducing its light output An 85 mm Chance Brothers Incandescent Petroleum Vapour Installation. The mantle is a roughly pear-shaped fabric bag, made from silk, ramie-based artificial silk, or rayon. The fibers are impregnated with metallic salts; when the mantle is first heated in ...
Inversion of strong negative isostatic gravity anomalies in confined deep basins caused by upper crustal stretching. Critical to whether a basin becomes inverted are, also, the timing of a compression phase relative to the initial basin-forming extensional event and the extensional strain rate.
Alternatively, the gas can be cooled down after the compressor again, as it gains some heat in the compression process, and then released. The heat received in the heat-exchangers between the turbine and compressor and after the compressor may be used for heating, providing the cogeneration mode of the system operation.
Gas lighting fitted, in the form of inverted gas mantles 1909: New pipe organ installed at a cost of £450 1921: Electric lighting fitted 1939: Chancel and choir vestry repaired and a concrete raft was built beneath the East Wall 1962: Heating changed from coal to oil 1994
Recuperator [16] – If the Brayton cycle is run at a low pressure ratio and a high temperature increase in the combustion chamber, the exhaust gas (after the last turbine stage) might still be hotter than the compressed inlet gas (after the last compression stage but before the combustor). In that case, a heat exchanger can be used to transfer ...
A Clamond basket is a kind of gas mantle, invented in the 1880s by the Parisian Charles Clamond, [1] and which he later patented in the United States. [2] It was the first economically practical gas mantle, since prior mantles had involved expensive materials like platinum and iridium.
Drawing the retorts at the Great Gas Establishment Brick Lane, from The Monthly Magazine (1821). The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century.
