News of work on Sir Archibald Sinclair's boiler26 October 2001Work started again on Sir Archibald Sinclair's boiler some weeks ago. Several major components are being renewed, including the firebox tubeplate, inner throatplate, foundation ring corners, inner wrapper lower sides, and thermic syphon tubes.
In June the replacement firebox tubeplate and inner throatplate sections were delivered.
The front left bottom corner, showing the old corroded plate, and after cutting out the bad sections.
The inner throatplate, which forms the floor of the combustion chamber. The left picture shows the old plate which was distorted, and the right shows the bad section cut out. The two columns are the lower tube-sections of the thermic syphons.
The lower sides of the thermic syphon tubes have been cut away for replacement, and the firebox inner wrapper sides have been cut out for their whole length just above the grate.
With the firebox tubeplate removed the staying system is more easily seen.
The new firebox tubeplate ready for installation. More pictures can be found here.
