We know that the rocket burns clean, but how clean is the rocket when it comes to fine particle emissions? I have not seen any test results yet and it is an important matter if we want to develop the rocket into a mainstream heating option. That is why I invited a german company to test a batch rocket and to see if it would comply to the German standard. In Europe the Austrians and Germans have the strictest rules when it comes emissions, so when it will pass this test, it might pass anywhere all over the world. The german company used TUV certified (comparable with the ETA in the US) equipment and protocol. I was uncertain if the rocket would pass the test, rockets have a relatively high turbulence in their firebox, which is not in favor of particle emissions. But it did PASS THE TEST, with ease. It released 0,014 gr/m3 where 0,04 was allowed! For more info see: rocketstove.nl/technical-info/technical-info-fineparticlewww.youtube.com/watch?v=M1HDMwy6PRY

wonderful! what about NOx & SOx ?

pioniers, That's great news! Congrats, and what morticcio said, too! Maybe our EPeeAY can get over themselves Eric VW

Great!
I have a question which is not so important because only results count : Do you think that low measurements in small particule is due to the quality of burning, to the fact that small particules have time to fall down on the floor of the bell exchanger or both reasons?

Great Sjang. Pyrophile... The bell system bring a lot improvement allready... I was amazed that the channel system vs. the bell system has such a difference. It is interesting that ortner firebox which passes all test if it will be equipped with the bell system will have more than 2 times less PMs. stovemaster.com/html_en/testing_at_ortner_gmbH_2014.html

Is it stupid to imagine that good results in small particules could be due to the fact that particules fall at the bottom of the bell? Depending of the kind of firebox, you can find many ashes on bell's floor!
Saying that is not a critic : I am building bells! I just try to understand.

Is it stupid to ùmagine that good results in small particules could be due to the fact that particules fall at the bottom of the bell? Depending of the kind of firebox, you can find many ashes on bell's floor! The tests are made for particulate matter 2.5, which means the particle size is 2.5 micron or less. From what I've read about these, the dust is so fine it behaves like a gas in the exhaust stream. In a straight batch box there's lots of fly ash in the bell, in particular when burning soft woods because the ashes are carried out of the combustion chamber. Very little is left behind after a good burn. What is on the firebox floor feels like sand, sintered like very small clinkers. Nevertheless, it would be very intersting to know what a comparable system with p-channel would do. That way one would know whether there is or isn't improvement and what the difference might be. A batch box that passed the test is only interesting when one would like to certify that particular heater.
