  • How to Destroy a Boiler -- Part 1

    The boiler is actually an oversized distillery in that the water that enters the boiler is vaporized to steam, leaving the solids behind. Depending on the amount of solids in the water, or hardness, the residue is sometimes visible when a pot containing water is boiled until all water is vaporized.

    2019-5-16 · Sludge is the accumulation of solids that precipitate in the bulk boiler water or enter the boiler as suspended solids. Sludge deposits can be hard, dense, and tenacious. When exposed to high heat levels (e.g., when a boiler is drained hot), sludge deposits are often baked in place. Sludge deposits hardened in this way can be as troublesome as

  • Boiler feedwater - Wikipedia

    2019-4-30 · Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it

  • Boiler Blow Down Prevents Scale and Corrosion |

    When boiler water turns to steam, solids are left behind. Unless the condensate return is , the hardness and dissolved solids will cycle up when the boiler takes on makeup water. On hot water systems, no makeup water is generally used. The solids concentration remains the same and no blowdown is needed.
