Preparatory work on the boiler of number 155 has begun in Pretoria with the old tubes being removed and the tube plates and boiler internals thoroughly cleaned. We now have the specifications for the Gas Producer Combustion System (GPCS) inlets on each side of the firebox which comprise a hollow boiler stay with a steel insert. At each outer end are “swirler” plates which rotate the air entering the firebox above the fire bed. Amazingly we have located a number of new ones in the Sandston store which must have arrived with 155 so many years ago that they were forgotten! Our picture gallery shows arrival in Pretoria and work on removing the tubes and cleaning the boiler in preparation for the retube.
