biomass heating environmental concern danger

[chazvan]

There appears to be an effort afoot to go after those burning biomass (read wood heating) on the basis that the particulates emitted kill large numbers of people.  While am guessing the an RMH traps most particulate, if this public scare gets out of hand, it could become a problem for all of us.

See the link to the recently published bit below.

Maybe we will have to filter our exhaust.  I did observe my test rocket stove (not rmh) emitting tiny bits of ash and small sparks yesterday evening.

Running a different oval heat riser configuration. Different wood. Lots of fine white bits of ash out the heat riser top. If it were dusk I am sure many would be glowing as they stink when they hit my skin. Would not want to run this on a hot dry low humidity day or would likely set the country side afire. Again, this is just an open top rocket stove, not an RMH. The point is, even with a clean looking burn, there is particulate coming out. In and RMH situation, the final exhaust should be cool enough to run through a cyclone/bag filter unit if there is still particulate in the exhaust stream.

RMH is more clean then electricity.
