    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

    Fire-tube boiler - Wikipedia

    A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low

    Choosing The Right Boiler: Watertube vs. Firetube - Boiler

    Jun 13, 2013 · From a cold start, the firetube boiler, due to its larger water volume, takes longer to bring up to operating temperature or pressure vs. a similar sized watertube boiler. With less water volume, a watertube boiler can follow load swings more precisely and generally has better turndown.

    Sep 14, 2015 · In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water
