ANALYSIS OF BOILER EFFICIENCY CASE STUDY OF

2.2.1 Fire tube boilers Fire tube boilers consist of a series of straight tubes that are housed inside a water-filled outer shell. The tubes are arranged so that hot combustion gases flow through the tubes. As the hot gases flow through the tubes, they heat the water surrounding the tubes. The water is confined by the outer shell of boiler. To avoid the need for a thick outer shell fire tube boilers are used for lower

The favoured area of nucleation is in tube holes of drums where there has been an ingress of boiler water often of high pH. In high pressure units tubes are often welded to the drum which creates a high residual stress field.
