My first thought is to have an elaborate set of pipes that the exhaust travels through, to give it more time to "heat exchange". But if the pipes are too small diameter, I think it might not "draft" as well (breath properly, to get enough oxygen/air for combustion) 03:17 < nmz787> second thought is shorter but still longer than normal pipe, with some sort of electric arc, or something... sparking a plasma inside, getting it hotter, and thus making heat exchange more likely before the gas escapes 03:17 < nmz787> (also that would be environmentally more friendly, burning the otherwise unburnt particles) 03:21 < fenn> first concern is combustion efficiency. need to inject air that has been preheated into the flames to completely burn the soot and tar gas 03:22 < fenn> as long as it's completely combusted it doesn't matter what the airflow rate is 03:22 < fenn> once you have pure CO2 and H2O going out the chimney you can cool it off all the way without worrying about creosote buildup 03:27 < nmz787> I could just get a pile of car junkyard radiators and pipe the exhaust through them for heat exchange. Place a radiator inside the firebox to add that extra heat you're talking about too 03:27 < fenn> basically you make a counterflow heat exchanger for the secondary air inlet 03:27 < fenn> car radiators are made of copper or aluminum and would melt 03:30 < fenn> http://fennetic.net/irc/crown_royal_stoves_SG_animation_2019.gif 03:33 < fenn> for sucking the heat out you can put fins on your exhaust pipe 03:34 < fenn> a long flat box as the exhaust pipe will have a lot of internal surface area but still be easy to clean 03:34 < fenn> though it shouldn't need any cleaning if you do everything else right 03:34 < nmz787> https://hackaday.com/2019/07/20/a-microwave-kiln-from-scratch/ 03:35 < nmz787> maybe coating the heat exhanger in something like that would help shield it from melting? 03:35 < nmz787> "ceramic fibre insulation, which is bonded both to itself and to the fused silicon carbide grit by a cured solution of waterglass, sodium silicate" 03:35 < fenn> um.. then it wouldn't be exchanging any heat 03:35 < nmz787> hrmm 03:36 < fenn> just use sheet steel 03:36 < fenn> stainless will last longer but transfers less heat 03:36 < nmz787> but the exhaust will have to loop back through the stove right? 03:37 < nmz787> because the air added to the exhaust will cool it too much 03:37 < fenn> did you look at that gif? 03:37 < nmz787> yeah, where's the fire? 03:37 < nmz787> in the bottom or the middle? 03:37 < fenn> the logs sit on the bottom, and the fire is sort of in the middle 03:38 < nmz787> which is the exhaust-injection? 03:38 < nmz787> the bottom or the middle intake? 03:38 < fenn> the gray thing near the bottom is the grate 03:39 < fenn> the gray thing near the top is the secondary air inlet heat exchanger 03:39 < fenn> i'm not sure what the gray circles represent 03:41 < nmz787> wow those crown royal stoves are 99% efficient 03:41 < nmz787> I've been hearing about these "outdoor stoves" lately 03:44 < fenn> might be interesting to play around with an O2 sensor from a car exhaust 03:44 < nmz787> hmm, yeah 03:45 < nmz787> my "new" stoves are destined to be replacements for backyard campfires really, so I don't have any serious motivation to make them ultra efficient... but I'm starting to think on the topic anyway, possibly for later practical applications/projects 03:45 * nmz787 sleeps 03:45 < fenn> less smoke always seems like a plus 03:46 < nmz787> yeah 03:46 < nmz787> I can feel better about burning stuff 03:46 < fenn> rocket stoves is a project to do this cheaply fwiw 03:47 < nmz787> and more effectively make the trees above my house even more cannibalistic 03:47 < nmz787> ah, yeah I've looked into them years ago 03:48 < nmz787> I really liked the russian hearth fireplaces 03:49 < nmz787> basically huge masses of masonry, with a bunch of back and forth exhaust pathways inside it 03:49 < nmz787> https://en.wikipedia.org/wiki/Russian_stove 03:51 -!- mauz555 [~mauz555@2a01:e0a:56d:9090:b8ab:c195:3051:6360] has joined ##hplusroadmap 04:30 -!- mauz555 [~mauz555@2a01:e0a:56d:9090:b8ab:c195:3051:6360] has quit [] 04:38 < TMA> nmz787: add oxygen (force feed the air with a blower) -- this burns the fuel more efficiently and less ash remains as a result [of course this is in addition to the heat capture on the exhaust, not a replacement] 06:21 -!- filipepe [uid362247@gateway/web/irccloud.com/x-ljqdgjikjrssrtrk] has quit [Quit: Connection closed for inactivity] 07:02 -!- spaceangel [~spaceange@ip-89-177-23-46.net.upcbroadband.cz] has joined ##hplusroadmap 07:57 -!- hehelleshin [~talinck@98.29.27.253] has joined ##hplusroadmap 08:01 -!- helleshin [~talinck@98.29.27.253] has quit [Ping timeout: 264 seconds] 08:15 -!- yashgaroth [~ffffffff@172.58.22.238] has joined ##hplusroadmap 08:50 -!- CryptoDavid [uid14990@gateway/web/irccloud.com/x-pegevutcbqvrretm] has joined ##hplusroadmap 09:43 -!- yashgaroth [~ffffffff@172.58.22.238] has quit [Ping timeout: 256 seconds] 09:48 -!- aeiousomething [~aeiousome@unaffiliated/aeiousomething] has joined ##hplusroadmap 09:51 -!- Urchin [~urchin@unaffiliated/urchin] has quit [Remote host closed the connection] 10:08 -!- yashgaroth [~ffffffff@172.58.19.12] has joined ##hplusroadmap 10:56 -!- nanotube [~nanotube@unaffiliated/nanotube] has quit [Ping timeout: 256 seconds] 11:05 -!- nanotube [~nanotube@unaffiliated/nanotube] has joined ##hplusroadmap 11:36 < kanzure> .tw https://twitter.com/gregeganSF/status/1244051199638175745 11:36 < saxo> In 20 years, will nanopore DNA sequencers be as common on smartphones as cameras?
