Hi All


Are there scientistic papers about the rocket mass heater like excaust polution somewhere on the internet, are
the universities who did test or laboratoria in Austria.

Past wednessday I was by the judge, because one nabure complain about the steel woodstove, that is why I plan
a rocket mass, I go design a electrostatic filter to catch fine particles, that design is far ready, did the electronic
high voltage part who is done now.

If somewhone has tests with these RMH I like to see it, so I get a idea about a RMH polution in excaust. also
a Batch rocket is welcome, looks almost the same.

Thanks.

Hi Kees;
I don't know of any scientific papers published. There may be something out there & I haven't heard of it.
The next best person would be Peter van den Berg, he is a master builder and owns and uses a testo meter for emissions.  He may have some documentation  that a judge might consider "scientific" evidence.

you can read this https://permies.com/t/25954/Rocket-Mass-Heater-Compliance-Code but most authorities want to see the PM 2.5 and as far as I can tell no one has measured this from a RMH yet.

This is an interesting study https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0165529&type=printable which looks at biofuel stoves used indoor including various rocket stoves, and has some PM2.5 data but not really applicable in your case.

Thanks Graham, I go read.


Put a rocket in mine home in holland is not such a issue because a company do sell a metal woodstove with the same rocket technologie, who is certified,

So I have to call mine inshurance agent before deciding, mine home is complete stone not a wooden one like common in usa, so nothing much burnable.

I can buy a new stove with rocket technologie like in pic.

Did read, I see it get,s quite low with the PM2.5 these afrikan people has now a quite clean way of cooking with much less wood. I presume when use a more
controlled mass heater with a rizer, these are even cleaner, some say these do almost equal to gas CV type.

I'd like to bump this thread up and see if any thing has changed in the last year.

The Guardian just published this short article, acting as a megaphone for organizations in the UK that are concerned with asthma: https://www.theguardian.com/environment/2021/jan/01/avoid-using-wood-burning-stoves-if-possible-warn-health-experts

The general upshot for the TLDR crowd ... PM2.5 is really nasty, most "wood stoves" create real problems with PM2.5 in both the atmosphere and in the home.  That's not good for the region or the people in the home.

Now, I "know" that a good rocket stove/heater will be very clean as measured by the mix of gases exiting the system (basically, no oxygen or combustible gases) and any masonry-style stove that promotes a hot and complete burn, a long exhaust channel, etc SHOULD also have very low particulate counts.  But I can't prove that.

I fired up Google and SwissCows and poked around using terms such as "rocket stove pm2.5" and "rocket heater pm2.5" and some variations.  I found numerous DISCUSSIONS (mostly here ...), some numbers for cookstoves intended for use in 3rd world countries** -- so I've got nothing to share.  

Does anyone have concrete information to share?

** Idea ... recycle glass from old stovetops for use as a cook surface instead of an open flame under a pot.  Berkeley and the Livermore Lab did a whole study on air injection to PM2.5 (https://www.osti.gov/biblio/1342536) ... but an enclosed burn chamber would be a lot more effective!

You mean like these Walker Stove designs? :-)

Almost ... I'm thinking about cutting them down to a single pot size, that way they could have spare glass tops!
