      Mar 27, 2019 · When a boiler runs a leak, high temperature water or steam flows out at an extreme pressure. In Eskom 70% of tube failures result in a forced outage, with boiler tube failures being the leading cause in failure of generation. Fly ash erosion is the leading cause of leaks.

      The water/steam mixture from the radiant furnace tubes is collected in a steam drum. From here steam flows through the low-temperature pendant super-heaters, the super-heated radiant wall tubes and further to the pendant super-heaters. Its temperature is increased to 540ºC at a pressure of 17.24 MPa.

      To achieve this, the condensate is passed through numerous heaters before feeding it into the boiler. All the heaters are of the surface type in which the water flows through tube nests. Steam extracted from different stages of the turbine heats the water by conduction through the tube metal.

      Boiler Safety. Water-tube boilers are known to be safer than their fire-tube counterparts from an operational standpoint. The feature that makes water-tube boilers so much safer is the volume of water contained. In a water-tube boiler, it contains a minimal amount of water at any given time.

      What are the Different Components or Parts of a Boiler

      In order to increase the insulation of boilers, we use the water wall tubes. In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler. These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed

      The flue gas velocities are too high, causing excessive erosion of the burners, as well as of the furnace tubing. The change during the early contract stage from the tube mills originally specified, to vertical mills, was a major error. The change was proposed by the boiler contractor with a price reduction, which Eskom accepted.

      Yarrow boilers are an important class of high-pressure water-tube boilers.They were developed by Yarrow & Co. (London), Shipbuilders and Engineers and were widely used on ships, particularly warships. The Yarrow boiler design is characteristic of the three-drum boiler: two banks of straight water-tubes are arranged in a triangular row with a single furnace between them.

      Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

      Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
