Boiler Installation

an aggregate of equipment used to obtain steam under pressure (or hot water).

A boiler installation consists of a boiler unit and auxiliary equipment such as gas flues, air ducts, steam and water pipelines and fittings, and induced and forced draft equipment. Low-power boiler installations usually do not have all of the above auxiliaries, but they do include a feed pump with accessories and equipment for water treatment. Such boiler installations, like water-heating boilers and powerful plants of heat and electric power stations and industrial enterprises, usually consist of several units located in a boiler room (boiler shop), with a common feed main and with sectionalized steam piping. A boiler room usually has standby (backup) boiler units, so that a unit can be repaired without a decrease in the total output of steam or hot water. High-power boiler installations operating with intermediate steam superheating are a part of an aggregate called a boiler-turbine unit. In this case the repairs of the boiler plant, turbine, and generator are conducted concurrently. High-power boiler installations occupy a space of hundreds of thousands of cubic meters, burn as much as 600 tons of fuel per hour, and produce up to 4,000 tons of steam per hour.
