Low Sulphite Values In Steam Boilers

BOILERS | Energy-Models.com

2021-3-2 · Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

Sulfite & Catalyzed Sulfite in Steam Boilers |

2020-8-21 · Why Is Sulfite Used In Boilers? Sulfite is a very important chemical used to scavenge oxygen in steam boilers. Sulfite reacts with oxygen and produces sulfate. As you know, dissolved oxygen in boilers can cause a rapid corrosion known as pitting. An oxygen scavenger is a chemical that consumes oxygen through an oxidation-reduction (redox) reaction.

It includesmost steam boilers, the exception being those of the 'once through' or coil type, where there is no steam drum. In such cases, steam outlet temperatures exceeding a pre-set value are taken to indicate insufficient water input. In most cases, the simple gauge glass on the steam / water drum or boiler shell is used as the indicator.
