| steam | 1. To emit steam or vapor. "My brother's ghost hangs hovering there, O'er his warm blood, that steams into the air." (Dryden) "Let the crude humors dance In heated brass, steaming with fire intence." (J. Philips) 2. To rise in vapor; to issue, or pass off, as vapor. "The dissolved amber . . . Steamed away into the air." (Boyle) 3. To move or travel by the agency of steam. "The vessel steamed out of port." (N. P. Willis) 4. To generate steam; as, the boiler steams well. Origin: Steamed; Steaming. 1. To exhale. 2. To expose to the action of steam; to apply steam to for softening, dressing, or preparing; as, to steam wood; to steamcloth; to steam food, etc. 1. The elastic, aeriform fluid into which water is converted when heated to the boiling points; water in the state of vapor. 2. The mist formed by condensed vapor; visible vapor; so called in popular usage. 3. Any exhalation. "A steam og rich, distilled perfumes." Dry steam, steam which does not contain water held in suspension mechanically; sometimes applied to superheated steam. Exhaust steam. See Exhaust. High steam, or High-pressure steam, steam of which the pressure greatly exceeds that of the atmosphere. Low steam, or Low-pressure steam, steam of which the pressure is less than, equal to, or not greatly above, that of the atmosphere. Saturated steam, steam at the temperature of the boiling point which corresponds to its pressure; sometimes also applied to wet steam. Superheated steam, steam heated to a temperature higher than the boiling point corresponding to its pressure. It can not exist in contact with water, nor contain water, and resembles a perfect gas; called also surcharged steam, anhydrous steam, and steam gas. Wet steam, steam which contains water held in suspension mechanically; called also misty steam. Steam is often used adjectively, and in combination, to denote, produced by heat, or operated by power, derived from steam, in distinction from other sources of power; as in steam boiler or steam-boiler, steam dredger or steam-dredger, steam engine or steam-engine, steam heat, steam plow or steam-plow, etc. Steam blower. A blower for producing a draught consisting of a jet or jets of steam in a chimney or under a fire. A fan blower driven directly by a steam engine. Steam boiler, a boiler for producing steam. See Boiler, 3, and Note. In the illustration, the shell a of the boiler is partly in section, showing the tubes, or flues, which the hot gases, from the fire beneath the boiler, enter, after traversing the outside of the shell, and through which the gases are led to the smoke pipe d, which delivers them to the chimney; b is the manhole; c the dome; e the steam pipe; f the feed and blow-off pipe; g the safety value; hthe water gauge. Steam car, a car driven by steam power, or drawn by a locomotive. Steam carriage, a carriage upon wheels moved on common roads by steam. Steam casing. See Steam jacket. Steam chest, the box or chamber from which steam is distributed to the cylinder of a steam engine, steam pump, etc, and which usually contains one or more values; called also valve chest, and valve box. Steam chimney, an annular chamber around the chimney of a boiler furnace, for drying steam. Steam coil, a coil of pipe, or collection of connected pipes, for containing steam; used for heating, drying, etc. <chemistry> Steam colours, the space in the boiler above the water level, and in the dome, which contains steam. Steam table, a table on which are dishes heated by steam for keeping food warm in the carving room of a hotel, restaurant, etc. Steam trap, a self-acting device by means of which water that accumulates in a pipe or vessel containing steam will be discharged without permitting steam to escape. Steam tug, a steam vessel used in towing or propelling ships. Steam vessel, a vessel propelled by steam; a steamboat or steamship; a steamer. Steam whistle, an apparatus attached to a steam boiler, as of a locomotive, through which steam is rapidly discharged, producing a loud whistle which serves as a warning signal. The steam issues from a narrow annular orifice around the upper edge of the lower cup or hemisphere, striking the thin edge of the bell above it, and producing sound in the manner of an organ pipe or a common whistle. Origin: OE. Stem, steem, vapor, flame, AS. Steam vapor, smoke, odour; akin to D. Stoom steam, perhaps originally, a pillar, or something rising like a pillar; cf. Gr. To erect, a pillar, and E. Stand. Source: Websters Dictionary (01 Mar 1998) |
| steam conversion factors | (approximations) 1 pound of steam = 1,000 Btu = .3 kW. 10,000 lbs/hr steam = 300 boiler horsepower. (05 Dec 1998) |
| steam engine | An engine moved by steam. In its most common forms its essential parts are a piston, a cylinder, and a valve gear. The piston works in the cylinder, to which steam is admitted by the action of the valve gear, and communicates motion to the machinery to be actuated. Steam engines are thus classified: 1. According to the wat the steam is used or applied, as condencing, noncondencing, compound, double-acting, single-acting, triple-expansion, etc. 2. According to the motion of the piston, as reciprocating, rotary, etc. 3. According to the motion imparted by the engine, as rotative and nonrotative. 4. According to the arrangement of the engine, as stationary, portable, and semiportable engines, beam engine, oscillating engine, direct-acting and back-acting engines, etc. 5. According to their uses, as portable, marine, locomotive, pumping, blowing, winding, and stationary engines. Locomotive and portable engines are usually high-pressure, noncondencing, rotative, and direct-acting. Marine engines are high or low pressure, rotative, and generally condencing, double-acting, and compound. Paddle engines are generally beam, sidelever, oscillating, or direct-acting. Screw engines are generally direct-acting, back-acting, or oscillating. Stationary engines belong to various classes, but are generally rotative. A horizontal or inclined stationary steam engine is called a left-hand or a right-hand engine when the crank shaft and driving pulley are on the left-hand side, or the right-hand side, respectively, or the engine, to a person looking at them from the cylinder, and is said to run forward or backward when the crank traverses the upward half, or lower half, respectively, of its path, while the piston rod makes its stroke outward from the cylinder. A marine engine, or the engine of a locomotive, is said to run forward when its motion is such as would propel the vessel or the locomotive forward. Steam engines are further classified as double-cylinder, disk, semicylinder, trunk engines, etc. Machines, such as cranes, hammers, etc, of which the steam engine forms a part, are called steam cranes, steam hammers, etc. Back-acting, or Back-action, steam engine, a steam engine in which the motion is transmitted backward from the crosshead to a crank which is between the crosshead and the cylinder, or beyond the cylinder. Portable steam engine, a steam engine combined with, and attached to, a boiler which is mounted on wheels so as to admit of easy transportation; used for driving machinery in the field, as trashing machines, draining pumps, etc. Semiportable steam engine, a steam engine combined with, and attached to, a steam boiler, but not mounted on wheels.
