      Boilers create steam&nbsp; The fuels used to heat industrial boilers include coal, oil, natural gas or nuclear fission. When water turns into steam, its volume expands more than 1,000 times - and it can traverse steam pipes at more than 25 m/s. As a result, steam provides an effective way to move energy and heat around a plant, from a central boiler to wherever it is needed.&nbsp; The biggest issue associated with boilers is the fact that water’s life-giving properties also encourage bacterial growth, which fouls boiler surfaces. Water also dissolves gases (like oxygen and carbon dioxide) which can corrode metals. Corrosion is the reversion of a metal to its original ore form – so the iron used to construct boilers can revert to&nbsp;iron&nbsp;oxide as the result of corrosion.&nbsp; If left untreated, scale deposits and fowling diminish a boiler’s efficiency, and can lead to unplanned downtime. The feed water used for boilers must be as pure as possible, with minimal suspended solids and dissolved impurities.&nbsp; Metering pumps are used to treat boiler feed water, in a variety of ways
