[Stoves] Ways of testing combustion/emissions

[Crispin Pemberton-Pigott]

Dear Frank

The practical use of your attempts to calculate the mass of fuel burned is
the testing of heavy and fixed stoves like brick institutional stoves.

>fuel burned just from the emissions.

You don't need to measure the velocity of the gases, you only need to get a
gas sample from the stove rather than a hood above it. That gives you the
total carbon and the excess air diluting it.  The rest is Gr 6 math.
Determining the velocity accurately is far more difficult than taking your
gas sample from the stove instead of the hood.
