Steam Accumulators | Spirax Sarco

When steam demand from the plant is low, and the boiler is capable of generating more steam than is required, the surplus steam is injected into a mass of water stored under pressure. Over a period of time the stored water content will increase in temperature and pressure until it finally achieves the saturation temperature for the pressure at which the boiler is operating.

How to Destroy a Boiler -- Part 1

For example, a steam drum that is operating at normal water level has the bottom half of the drum cooled by water and the top half by air initially and steam eventually. If one starts to fire the boiler from a cold start, the water will heat up very quickly in the drum and the bottom half of the drum will expand much more quickly than the top half which is not in contact with water.

How a Water Tube Boiler Works | Miura America

If the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feedwater drum via the downcomer tube. This allows that water to re-enter the boiler's water supply, go back into the tubes, and once again be turned into useful steam.
