[Stoves] TLUD stoves and tests

[xvr.brandao at gmail.com]

Dear Ron,

 

« I assure you that I have plenty of company - and it will appear soon. »

Sure, anytime, I am always available to have a conversation with anyone who will wish to demonstrate how the WBT is a reliable protocol, and why it should be used.

 

« But that is not sufficient reason to drop the test. »

Then I don’t know what is.

 

Best,


Xavier

Dear Ron,

 

I don’t think the new ISO standard includes the WBT, I think you are the only person claiming that.

 

                [RWL:  I guess you will trust what the South Africa group thinks on this subject.  They failed in a fight to remove the WBT. 

 

                 I could send a copy of what has been approved - but that would violate the agreement I made to be part of the process.  

 

                I assure you that I have plenty of company - and it will appear soon.  

 

                What Nikhil has is possibly/probably 99% of the final.





 

Until there exists reviews of the WBT protocol demonstrating it is valid, the « cites for inadequacy that are very old » (some are from 2016 and 2017) will be the only proofs there is.

 

« [RWL3:   Can you give cites on these three sentences?  Maybe from some group that treats char as waste? »

See the table from Riva and al., Fuzzy interval propagation of uncertainties in experimental analysis for

improved and traditional three – Stone fire cookstoves below, this is with the WBT:

Some of the stoves tested were « Micro-Gasifier Stoves with FAN »

 

« [RWL4:   I have - and I recall no statements about TLUDs or char-making. »

 

                RWL:  I agree that the word micro-gasifier was there.  They still were only arguing for more tests - that I still claim aren't worth the extra effort.  Too much depends on the operator of the test.   But that is not sufficient reason to drop the test.  Just be satisfied if you and other groups can get within a few percent.

 

Ron
