Likely to be from the oxygen steelmaking, the gas from this process is
harder to process as fuel than the coke oven or blast furnace gas. It would
also fit with the change in colour of the gas. The composition of the gas
from steel making varies a lot during the blow while the coke oven and blast
furnace gasses are more stable in composition.
