Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. The potential for damage is more critical with solid fuel-fired boilers. A gas/oil boiler has no inventory or bed of

What is a Boiler? Boiler Definition . Boilers are defined as "Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.
