Exhausting Pipes (2)

After some time in the making, the machined new chimney bases have arrived from Mendip Steam Restoration Ltd. It's worth a look back at an earlier article for where these fit atop the boiler.

New Chimney bases, Blast Nozzles & Exhaust Pipes

The photo above shows clearly how the exhaust steam flow divides into two to feed the pairs of blast nozzles.

The short pipes showing against the orange pipes are the inlets for the blowers. More details are in this earlier article. Also try the label 'Chimneys' for all the relevant details on the subject.

The main difference between the old and new castings is the weight and hence strength. I used to be able to lift the old ones with difficulty; the new ones required help from a neighbour to get them out of my car! They are simply massive in construction and should last a very long time.

The trouble is that they will be very difficult to fit in place because of the weight! They also need the long chimney tubes to be fitted. Interesting times ahead!
