Such work, however, has a long history (Brimblecombe, 1987). Indeed, the very first volume of the venerable Philosophical Transactions
of the Royal Academy of Science published in 1687 in London contained
a description of a woodstove that burned wood extremely cleanly
(Justell, 1687 – see Supplement 1). This J-stove would be defined as a
cocurrent combustor in modern terminology and was subjected, by
the author, to a rather unique emissions monitoring technique to
prove clean combustion. The author applied an organic, widely available, renewable odorant, “cat piss”, to the fuel and if it was not detectable by smell in the exhaust, it was considered clean.
