[Stoves] Fuel test procedures

[Kevin Chisholm]

Dear Frank

You raise some very good points. Manures are a very good example of a case 
where alkali pumping could materially effect the gasification and combustion 
process.

A previous poster commented that he only wanted a simple procedure... simple 
procedures are possible when there are very few variables that can influence 
the outcome of the test.  In a case where it is possible for different 
Operators to do things differently, then it is necessary to have a more 
detailed test procedure specified, so that all Operators do indeed perform 
the test in the same manner.

Best wishes,

Kevin
