ICP is a Carrier subsidiary. ICP makes oil and gas furnaces, heat pumps, and central air-conditioning systems for residential and commercial customers. [1] It manufacturers, markets, and sells residential heating and cooling systems under the Arcoaire, Comfortmaker, Day & Night, Heil, KeepRite, Lincoln, and Tempstar brands; its commercial units, with up to 25 tons of cooling capacity, are sold ...
These furnaces were still big and bulky compared to modern furnaces, and had heavy-steel exteriors with bolt-on removable panels. Energy efficiency would range anywhere from just over 50% to upward of 65% AFUE. This style furnace still used large, masonry or brick chimneys for flues and was eventually designed to accommodate air-conditioning ...
Flash smelting with oxygen-enriched air (the 'reaction gas') makes use of the energy contained in the concentrate to supply most of the energy required by the furnaces. [4] [5] The concentrate must be dried before it is injected into the furnaces and, in the case of the Outokumpu process, some of the furnaces use an optional heater to warm the ...
An Automatic Oil Muffle Furnace, circa 1910. Petroleum is contained in tank A, and is kept under pressure by pumping at intervals with the wooden handle, so that when the valve B is opened, the oil is vaporized by passing through a heating coil at the furnace entrance, and when ignited burns fiercely as a gas flame.
Tube furnaces can also be used for thermolysis reactions, involving either organic or inorganic reactants. One such example is the preparation of ketenes which may employ a tube furnace in the 'ketene lamp'. Flash vacuum pyrolysis often utilize a fused quartz tube, usually packed with quartz or ceramic beads, which is heated at high temperatures.
A door at A allows access to the interior. The furnace shell rests on rockers to allow it to be tilted for tapping. Initially "electric steel" produced by an electric arc furnace was a specialty product for such uses as machine tools and spring steel. Arc furnaces were also used to prepare calcium carbide for use in carbide lamps.
Blast furnaces are currently rarely used in copper smelting, but modern lead smelting blast furnaces are much shorter than iron blast furnaces and are rectangular in shape. [76] Modern lead blast furnaces are constructed using water-cooled steel or copper jackets for the walls, and have no refractory linings in the side walls. [ 77 ]
1907: The first free flight of a rotary-wing aircraft is carried out by Paul Cornu. 1907: Leo Baekeland invents bakelite, the first plastic made from synthetic components. 1907: The tuyères thermopropulsives [454] after 1945 (Maurice Roy (fr)) known as the statoreacteur [454] [455] a combustion subsonique (the ramjet) [456] – R. Lorin [457 ...
