[Stoves] Equipment required for testing stoves

[Frank Shields]

Hi Crispin,

Weighing the fuel when removed (hot and burning) and dry weight after
soaking with water, draining (screen) and drying is not a convenient
procedure to determine moisture left -and prone to error - but only method I
can think of at the moment.
Water puts out a fire by taking away its heat. So wondering if there is
another method that could be used? Combination nitrogen gas and pieces of
steel in a tumbler? Must be some way besides water.

Dear Frank

You are on the right track, in my view. The assumed energy for the wood and
char is a major source of imprecision in the test. 

As for quenching with water: unfortunately we need to know the residual
moisture content of the fuel 'as removed'. That varies a lot depending on
the stove type. Quenching it with nitrogen is an alternative. 

Regards
Crispin
