Flued Boiler
A shell or flued boiler is an early and relatively simple form of boiler used to make steam, usually for the purpose of driving a steam engine. The design marked a transitional stage in boiler development, between the early haystack boilers and the later multi-tube fire-tube boilers. A flued boiler is characterized by a large cylindrical boiler shell forming a tank of water, traversed by one or more large flues containing the furnace. These boilers appeared around the start of the 19th century and some forms remain in service today. Although mostly used for static steam plants, some were used in early steam vehicles, railway locomotives and ships. Flued boilers were developed in an attempt to raise steam pressures and improve engine efficiency. Early haystack designs of Watt's day were mechanically weak and often presented an unsupported flat surface to the fire. Boiler explosions, usually beginning with failure of this firebox plate, were common. It was known that an arched st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chimney
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the '' flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term '' smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of ...

Puffing Billy (locomotive)
''Puffing Billy'' is the world's oldest surviving steam locomotive, constructed in 1813–1814 by colliery viewer William Hedley, enginewright Jonathan Forster and blacksmith Timothy Hackworth for Christopher Blackett, the owner of Wylam Colliery near Newcastle upon Tyne, in the United Kingdom. It was employed to haul coal chaldron wagons from the mine at Wylam to the docks at Lemington in Northumberland. History Precursors In 1810 the Durham Coalfield was disrupted by a major strike over the Bond system. During this time Christopher Blackett, owner of the Wylam Colliery, took advantage of the pit's idleness to experiment with the idea of a locomotive-hauled tramway worked purely by adhesion, rather than the Blenkinsop rack system used on the Middleton. These began with a simple hand-cranked wagon, converted from a coal wagon chassis with the addition of a central drive shaft and geared drives to the axles. As this experiment was successful, by 1812 it was follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Hedley
William Hedley (13 July 1779 – 9 January 1843) was born in Newburn, near Newcastle upon Tyne. He was one of the leading industrial engineers of the early 19th century, and was instrumental in several major innovations in early railway development. While working as a 'viewer' or manager at Wylam Colliery near Newcastle upon Tyne, he built the first practical steam locomotive which relied simply on the adhesion of iron wheels on iron rails. Early locomotives Before Hedley's time, such locomotives were far too heavy for the track that was then available. While most lines used cable haulage with stationary engines, various other schemes had been tried. William Chapman at the Butterley Company in 1812, attempted to use a steam engine which hauled itself along a cable, while, at the same company, Brunton had produced the even less successful "mechanical traveller", or ''Steam Horse''. However, in 1812, Matthew Murray and John Blenkinsop had produced the first twin cylinder steam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Firedoor
Boilers for generating steam or hot water have been designed in countless shapes, sizes and configurations. An extensive terminology has evolved to describe their common features. This glossary provides definitions for these terms. Terms which relate solely to boilers used for space heating or generating hot water are identified by (HVAC). A-B ; : A container beneath the furnace, catching ash and clinker that falls through the firebars. This may be made of brickwork for a stationary boiler, or steel sheet for a locomotive. Ashpans are often the location of the damper. They may also be shaped into hoppers, for easy cleaning during disposal. ; Blastpipe: Part of the exhaust system that discharges exhaust steam from the cylinders into the smokebox beneath the chimney in order to increase the draught through the fire. ; Blow-down: Periodic venting of water from the boiler. This water contains the most concentrated precursors for sludge build-up, so by venting it whilst still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applicatio ...
