Aug 20, 2019· This allowed shale and limestone to be deposited on top of them. The fossils in the shale and limestone change from shallowwater organisms to deepwater species, then back to shallow forms. Then sandstones appear as river deltas advance into the shallow seas and another coal bed is laid down on top. This cycle of rock types is called a cyclothem.
Within a few decades, the practice was to have a "stove" as large as the furnace next to it into which the waste gas (containing CO) from the furnace was directed and burnt. The resultant heat was used to preheat the air blown into the furnace. Hot blast enabled the use of raw anthracite coal, which was difficult to light, to the blast furnace.
