Aerial view of works showing Lodge-Cottrell plant & blast furnaces. On the right of the chimneys can be seen the pig-beds where the molten iron from the furnaces is run into rectangular depressions in beds of sand. On the left is the rectangular water-cooling tower, and the circular setting tank (Dorr Thickener) for the treatment of water used in the gas-cleaning plant. In the foreground is the plant by means of which the gases from the blast furnaces are freed from dust before being used for such purposes as heating the hot-blast stoves.
