Steam Boiler Maximum Temperature

Steam Boiler Maximum Temperature

Operating Controls - National Board of Boiler and Pressure

Steam boilers require a device which senses steam pressure and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating pressure. A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate.

Keep Steam Boiler Temperature on Maximum?

Because a steam boiler makes heat by producing steam - by boiling water, at sea level, the temperature at the boiler will be boiling or 212 °F or close to that figure. The actual steam boiler temperature may be a bit lower at high elevations above sea level, and the steam boiler temperature will be a bit higher than 212 °F for boilers operating at slightly higher pressures, as we'll illustrate in a table below.
