From Webster's Revised Unabridged Dictionary (1913) [web1913]: Boiler \Boil"er\, n. 1. One who boils. 2. A vessel in which any thing is boiled. Note: The word boiler is a generic term covering a great variety of kettles, saucepans, clothes boilers, evaporators, coppers, retorts, etc 3. (Mech.) A strong metallic vessel, usually of wrought iron plates riveted together, or a composite structure variously formed, in which steam is generated for driving engines, or for heating, cooking, or other purposes. Note: The earliest steam boilers were usually spheres or sections of spheres, heated wholly from the outside. Watt used the wagon boiler (shaped like the top of a covered wagon) which is still used with low pressures. Most of the boilers in present use may be classified as plain cylinder boilers, flue boilers, sectional and tubular boilers. {Barrel of a boiler}, the cylindrical part containing the flues. {Boiler plate}, {Boiler iron}, plate or rolled iron of about a quarter to a half inch in thickness, used for making boilers and tanks, for covering ships, etc {Cylinder boiler}, one which consists of a single iron cylinder. {Flue boilers} are usually single shells containing a small number of large flues, through which the heat either passes from the fire or returns to the chimney, and sometimes containing a fire box inclosed by water. {Locomotive boiler}, a boiler which contains an inclosed fire box and a large number of small flues leading to the chimney. {Multiflue boiler}. Same as {Tubular boiler}, below. {Sectional boiler}, a boiler composed of a number of sections, which are usually of small capacity and similar to and connected with each other By multiplication of the sections a boiler of any desired capacity can be built up {Tubular boiler}, a boiler containing tubes which form flues, and are surrounded by the water contained in the boiler. See Illust. {of Steam boiler}, under {Steam}. {Tubulous boiler}. See under {Tubulous}. See {Tube}, n., 6, and 1st {Flue}. From WordNet r 1.6 [wn]: boiler n 1: sealed vessel where water is converted to steam [syn: {steam boiler}] 2: a metal pot for stewing or boiling; usually has a lid [syn: {kettle}]
