Fire Tube Boiler - Definition, Construction, Working

The low-pressure range of fire tube is up to 20 bar whereas in water tube up to 250 bar. The load fluctuations in the fire tube cannot be handled whereas, in a water tube, it can be handled easily. This boiler occupies more floor area for output whereas, in a water tube boiler, it occupies less area.

Fire-tube boiler - Wikipedia

The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes

Characteristics of boiler feedwater - Lenntech

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, phosphates etc, in relation to working pressure.

Description of Boiler Tube Grades - Chicago Tube & Iron

BOILER TUBE GRADES CARBON STEEL SA178 Carbon steels show mild corrosion resistance and fair strength up to 1000F. However, their usage above 800F must take into account the susceptibility to graphitization. Graphitization has not been a significant problem in thicknesses encountered in boiler tubing. Use of heavy section pipe above 800F, however, is not recommended.
