- Field-tube_boiler abstract "A Field-tube boiler (also known as a bayonet tube)is a form of water-tube boiler where the water tubes are single-ended. The tubes are closed at one end, and they contain a concentric inner tube. Flow is thus separated into the colder inner flow down the tube and the heated flow upwards through the outer sleeve. As Field tubes are thus dependent on thermo-syphon flow within the tube, they must thus always have some vertical height to encourage the flow. In most designs they are mounted near-vertically, to encourage this.They are named after Edward Field, their inventor, and were originally developed for steam fire-engines where speed of raising steam was important. More recently, Field-tube boilers have been most widely used by French manufacturers, either for small vertical boilers, or as a marine boiler. The use of this type of Field tube has also been researched for the transfer of heat from nuclear reactors, vacuum condensers and heat exchangers.The thimble-tube boiler has some similarities, in that its water-tubes are also single-ended. The simpler thimble tube does not have the inner tube of the field-tube, therefore its flow is mixed, turbulent and dependent on random boiling. For this reason, thimble tubes can only be short, so are used in large numbers, and usually horizontally as their flow is not coherent enough to benefit from a gravity gradient. Field tubes are however more complex and expensive to manufacture. Field-tube boilers therefore use fewer and longer tubes (giving the same heating area for a reduced number of tubes).Field-tubes are always submerged, i.e. the upper end of the tube is mounted into the boiler below the water level, otherwise flow into the cold side of the tube cannot be replenished.The principal advantage claimed for Field-tube boilers is that there are none of the expansion problems experienced in boilers with simple tubes. Secondly, as Field-tubes are connected from just one end, their replacement and maintenance is simpler.One drawback of the field-tube is a tendency for mud and scale to accumulate in the bottom of the tube, potentially blocking circulation. The closed tube ends are also difficult to wash out. Providing an excessive dead space there as a mud reservoir would have poor circulation, thus risking local overheating. Efforts must thus be made to ensure that all tubes are equally heated and that all have strong circulation within them, encouraging enough flow to scour the tubes free of sludge.".
