[Stoves] Work for 2018

[CHRISTA ROTH]

Frank, you basically come back to what late Paal Wendelbo always said: START WITH THE FUEL, stove design depends on and should be linked to fuel substance and shape. 
The slide below is what I use in the Stoves101 for visualisation of that topic. 
and Crispin is right: we need the predictable fuel behaviour meaning standardised processed fuels so that the stoves have a chance for a predictable performance. 
There are years of science applied to the elaboration of liquid and gaseous fuels likeLPG and the fuels have to suit the elaborated standards, thus for the associated stoves it is easy to have a standardised performance if the fuel is predictable. it is not the stove that needs to be standardised. 
The clean cooking system goes well beyond a stove, but it includes more variables like the fuel, the user and the environment and ventilation space.

>> The Pellet Fuel Institute is a fine example of proper use of a biomass fuel. They have the test methods, certified labs and fuel requirements for the pellets to be used in pellet stoves. If we were to market clean burning pellet stoves to a receiving site we would need to include a pellet making machine and make sure there is available the proper feedstock that results in the quality pellets required.
>> 
>>  We need to do the same with our other biomass stoves. Write up the requirements for the biofuel to insure clean combustion, develop methods to measure them, certify labs to  test them and make sure the receiving site has the biomass suitable and a program in place to prepare and distribute the proper fuel for the stoves being used. A lot of work and Cecil will be busy preparing the people at the receiving site for the changes.
>> 
>> 
>>  I’m thinking people collect the biomass and deliver it to a location where its dried and prepared for stove use. Then deliver it where needed.
>> 
>> 
>>  The requirements for TLUDs will be different and requirements for briquette stoves different still. Biomass that is found to burn clean need be tested until we come up with limits for each stove classification. Perhaps for each stove depending how unique they are. So there is a lot of work to be done before we take them into the field.

>>  It may seem impossible but I see no other way that we can insure an improvement of air quality and most efficient use of fuel.
