Do you have questions about boiler controls?
Boilers can fail for three reasons. These are:
- Overpressurization of the boiler
- Insufficient water in the boiler causing overheating and vessel failure
- Pressure vessel failure of the boiler due to inadequate construction or maintenance
Keystone Steam Supplies carries a full line of products to regulate and control boiler operation in order to prevent the first two of these failure modes (the third one is out of our control).
Steam boilers have been in use for well over 200 years. In 1698, Thomas Savery, an English military engineer and inventor, patented the first crude steam engine which was developed to pump water out of coal mines. (Necessity is the mother of invention.)
