Parthibhan Abstract This article is focused towards the author's experience in the design and trouble shooting of Boilers related to the principle of natural circulation. Inadequate circulation causes tube failures. PoorSteam Boilers - 004 - Water and Steam DrumsNatural circulation in these boilers is obtained by rising of warmer water through generating tubes and lowering of cooler water through the downcomers. When the load is reduced, some of the generating tubes may allow water to flow down (thereby behaving like downcomers instead of generating tubes) to the water drum automatically.

What are the various types of tubes used in water tube boilers: - …

Boiler Tubes. Generating Tubes. These consists of numerous small diameter tubes placed in the main flow of hot gases, so forming a large heat exchange surface; the generation of steam takes place mainly by convection. For a given rate of water circulation the minimum allowable tube diameter is limited, as below a certain value the ratio of steam
