#PartQtyWhat it does
1 Boiler Barrel 1× Cylindrical steel shell forming the main water and steam space.
2 Fire Tube 140× Small fire tubes
3 Superheater Flue Tube 24× Large superheater flues
4 Superheater 2 parts 1× Bundle of elements that reheat saturated steam well above boiling point to raise efficiency and prevent condensation in the cylinders.
