The oxygen causes the metal to oxidize which lowers the melting point of the metal. Foaming and priming is caused when the boiler water does not have the correct amount of chemicals and there are suspended solids in the water which carry over in the dry pipe. The dry pipe is where the steam and water mixture are separated.

The start-up and shut-down of a system results in more stress on the boiler than continuous operation. A boiler is made up of many different types of materials which operate in different environments. These materials heat up and cool down at different rates. The standard warm up curve for boiler water temperature is 100°F per hour.
