Common Steam Boiler Problems & How to Troubleshoot Repairs

How a Steam Boiler Works. Steam boilers use a contained heat system to generate steam. The steam travels through pipes in the building's walls where they emerge at radiators in heating systems. The radiators warm from the steam's heat. As the steam gives off its heat, it condenses back to liquid water and returns to the tank.

Steam and Condensate - A basic overview of a steam system

As long as the amount of steam being produced in the boiler is as great as that leaving the boiler, the boiler will remain pressurised. The burner will operate to maintain the correct pressure. This also maintains the correct steam temperature, because the pressure and temperature of saturated steam are directly related.

Difference Between Low- and High-Pressure Boilers | Hunker

High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.

Steam Boiler: Sulphur Corrosion in Steam Boiler

The corrosion can be prevented if the metal temperature in the steam boiler is maintained in high temperature. The flue gas temperature exit of steam boiler is usually maintained at minimum 200 o C to avoid the formation of acid in air heater, economizer, stack and other pressure part also flue gas. For best design, the stack must be insulated to avoid cooling and corrosion.

The Relationship Between Water Temperature and Boiler

In a boiler pressure vessel as the water boils and steam is created this increases the pressure in the vessel which increases the boiling point. Those values that Eric gave you are the different boiling points of water at the different pressures. So to answer your question the water and the steam are at the same temperature.

Troubleshooting Steam Heating Boiler Problems

For this reason, many steam boilers have a low water cut-off valve that senses when water levels are dangerously low and turns off the burner beneath the boiler. If the boiler ran low on water, was refilled, but the burner will not turn back on, it is likely the low water cut-off valve needs to be reset.

We could raise the boiler temperature to, say, 300 C but this would elevate the steam pressure to 85 atm. Note that to raise the boiling point a little (76 K or 34%), we cause the boiler pressure to increase substantially (60 atm or 240%) thus demanding a much more robust and costly construction of the machinery.
