Lime Kiln playlist contents.
Calculating capacity of kiln in video 1 (based on ratio of 10:3 tons limestone:coal):
Specific gravities:
Limestone, broken
1554 kg/cu.m.
Coal, Bituminous,
broken 833 kg/cu.m.
(anthracite would be too expensive for this task)
1 cu m = 35.3147 cu.ft.
Converting from kg to uk tons
1554 kg = 1.52945694 uk tons/35.3147 cu.ft.
833 kg = 0.874959603 uk ton/35.3147 cu.ft.
So,
60 tons of broken limestone fills 1385.4 cu.ft.
15 tons of broken bituminous coal fills 605.4 cu.ft.
At 56% of the weight of limestone (based on the atomic numbers CaCO3 versus CaO), each of the 2 larger kilns would yield 25 tons of quicklime.
(Presumably, the BBC researchers found the figures for the capacity of both kilns at Morwellham Quay.)
