Originally, only half of the smoke chamber was to be replaced. Now we have decided to replace the entire smoke chamber (bottom left). We want to reuse the chimney base, so it has to come down as well (center). A little later, the wash hatches are prepared for the installation of new wash hatch liners (right).
The bottom ring of the firebox has now been welded on. It still needs to be straightened (bottom left). First, however, the tube wall flange is heated with the welding torch and straightened with targeted hammer blows (center and right).
Since the center wash hatch behind the blowpipe is very difficult to access, two additional wash hatches are installed laterally offset. The large-caliber pillar drilling machine is used for this purpose, operated by the workshop manager under the expert supervision of the expert.
A part of the so-called bootjack plate (the lower part of the standing boiler front wall) must also be replaced. First, the new part is bent in our friction spindle press. Then the edges are given their finishing touches. What sounds filigree, however, is rough but well-dosed manual work.
