(1) Blast furnace gas from the furnace.
(2) The boiler burned coal, both as secondary heat and as a pilot light to ignite incoming gas if flow from the furnace was interrupted.
(3) Burning gas passed up one side of the boilers, heating a nest of water tubes, then flowed down the other side, heating a second set of tubes, and out through the draft stack behind the boiler.

14. Operation diagram of the boilers.
The bottom drums served as “mud” drums. The sediment in the water was concentrated by evaporation and collected here. The mud drums were connected by a single row of horizontal tubes.

16. Delivery Track along Boiler Row.
Delivery tracks used to deliver coal to the boilers, and the ladle car traverse between the two furnaces receiving the hot molten iron. Once the ladle was filled then the ladle car was moved to the pig casting machine on the other end of the plant. There the hot molten iron is poured into pigs.
