Construction And Essential Of Water Tube Boiler

Description of Construction and Inspection Procedure

The boiler tubes are placed in the cylindrical boiler shell and enter into tube sheets at the firebox end and smokebox; they are surrounded by water and the combustion gases pass through them. Tube attachment is by rolling or prossering; the firebox tube ends are beaded and seal-welded, or just seal-welded.
