WEEK 12 - Day 46 Dismantling Furnace to Pan 5

This is getting to look like an archaeological site. With most of the superstructure dismantled we can see the flues underneath the salt pan.

The first photograph is looking east from the Stove house end looking towards the furnace front, but from the interior. The collapsed brick flue walls have been cleared to show the flue walls where they are infilled with flue ash, sand and cinder deposits. This a deliberate part of the construction to reduce the amount of bricks used in the furnace.The were four firing positions, with two 'dead-draft' flues along the outer walls to prevent the salt crystals from burning on the bottom of the pan as the crystals were drawn to the side. At the end of the pan (bottom of picture) the flue arrangement changes as the flue gasses were ducted underneath a walkway between the end of the pan and the front wall of the Stove House. The flue chamber is the wider infilled channel, with an ash filled space between each flue.

This second picture of Pan 5 furnace is taken looking west from the front of the furnace looking towards the Stove House 5. There is a clearer space within the flue at the fire end. Pan 5 was originally fired with coal or coke and later altered to burn recycled oil.
