The Greensplat engine is a Cornish beam pumping engine that was latterly used at a clay pit north of St Austell. The whole area where it was has now been mined into a big hole. The engine is displayed in the open and moved hydraulically - giving one an unprecedented view of a Cornish engine. This shows the condensing plant in its basic form. The green vessel on the left is the jet condenser and steam is fed into it by the black eduction pipe coming through the bob wall. Set in the concrete block is the coffin bottom connecting it to the air pump on the right and the air pump rod is seen coming down from the beam above. Painted red is the boiler feed pump that is also worked by a rod from the beam above. The feed pump sits on the eduction pipe - ingenious use of space and saves an extra bracket.
