THANK YOU Satamx!

VERY interesting! I actually learned a lot about these low profile "riser-less" stoves... (This one makes more sense to me with the short 12" riser though at least starting the upward draft.

Thanks again...

(Sitting here waiting for client to lay out some lines on some photos I sent him so I can continue styling sculpting... Going back to continue some of the internal mechanisms.)

Hi Satamax,

Do you have any links for the "broken riser" design? I'm totally unaware of what this is and I'm willing to research and learn anything and everything before starting to lay out a new design.

Thanks!

Richard

That totally fits our weather lately... and I totally understand.

It's been like this for a few days without any issues before this morning (although it has taken a little longer to get it started). I haven't been keeping track of the specific temps etc... I'm guessing we have been right on the "edge" of this phenomenon and today, it must have just crossed the line...

At least the solar heater kicks in on days like today! LOL!

Does this (can it), happen with other designs as well?

Is this where an insulated flue pipe going up the chimney or an insulated heat riser would help?

Thanks!

Richard

Just wanted to add:

I've heard where wind blowing over and down the masonry chimney can cause this type of behavior ... No wind (Under 2mph at most).

Speaking of "excellent draft"...

Today was the first time in almost a month of use, that I could not get this system going. (Note, before this morning, I've never experienced smoke back up the feed tube, while starting or re-starting.)

Cold air from the chimney, falling down and through the system was just too strong.

I usually fire this up using a propane torch (wide paint burning nozzle), to "prime" my draft instead of using paper to heat up the burn tunnel and first riser duct. The down draft was so strong that it blew the flames back from the nozzle... Not violently, but enough where I could see that if I lit anything flammable, the smoke would just enter the house, tripping off our alarms...

It usually takes about 1 to 2 minutes max (using the propane torch), to prime the system and switch over to a few light pine sticks to really get it going before switching to hardwoods... After 5 minutes of propane torch, the IR temps on the ducting would just fall rapidly when I removed the torch (I'm assuming from the cold air falling down from the chimney?)

Didn't check temps outside or barometric pressure etc.. Temps have been fairly mild the last couple of days... 39-40 at night, 55-60 day. Indoor temp is 68.

Any ideas on what's taking place?

Thanks!

Richard

Hi Glenn,

Thanks!

It's that "horizontal afterburner" (Is this the same as the burn tunnel in this riser-less design?), that I'm trying to get my hands around mentally... I thought the riser (a tall one), was the heart of a rocket stove providing the draft to bring the temps up?

As for the glass, I'm totally fine with just a glass door at the batch box opening... safety and a little view....

I need to turn off the sound of my computer in my studio.... (or not LOL!), it "rings" me every time I get an email which includes notifications to this thread! LOL!

Got my strategy down and getting tasks done.... The hard part is not creating drawings before fabricating.... Some of my best "sketching" happens during the building.... I can see complicated 3-D transnational styling better as I create it... three-view drawings don't always take into account how the three views match up! (fear of proceeding and the fun of watching it come to life. Wish me luck!

I had "assumed" that Glenn's design was a batch box... After reading through several other threads, I had planned to discard the J-tube for a batch box... "From what I've read", a batch box will have longer burns (less feeding frequency)? Within the "secondary port" design thread, I thought I had read that walker was able to get burn times as long as 2 hours? That would sure be nice. (Right now, my best is between 30 and 50 minutes when using hardwoods, from best flame/draft. down to mostly coals and maybe a few licks of flame.)

Also (after speaking with Tresa), she really liked the idea of a glass door so that we could gain the "emotional atmosphere" of a "cheery, burning fire".

Just finishing breakfast after writing down today's step-by-step agenda for working on my project... Now I have a long list of tasks to get done.

Hi Glenn,

Thanks for the added info...

I am "familiar" with the plunger tube... found it mentioned in other threads and have an "idea" as to its' function...

I also know I have a LOT of calculating to do regarding surface area, batch box feed CSA etc....

First I have to fully understand how this riser-less system works... I've seen the brick layouts (layer by layer) in photos, but no real "plans" per se....

I was thinking of hot wiring a miniature version of the brick layers to get a better view from all directions (inside and out), to get a better idea as to how it works...

Unfortunately, my current client added some details to my prototype project that really have me super crunched for time... He leaves for China on the 7th or so and I need to get this to him in LA before then...

I'll not be "gone"... Just super busy! I'll come back here to read additional posts, but don't feel you're wasting your time if I don't respond... Just time management issues.

Thanks!

Richard

Yes he is! And I'm so grateful! I finally feel like I'm on the right track to design and fit a system that will provide everything I wanted, from long burns (using the secondary port concept), to a radiant heat I can tap in with using a small fan to blow the hot air towards our central heat air intake to getting more mass heat stored for longer warming during the night.... and, having it look "nice", not being visually intrusive into our living room! =D

Not sure if I shared this before, but over the past few days, I ran a test (of sorts), to see what kind of impact my solar heater and existing rocket heater was having on our power bill.

Took a reading at the meter as my "base line". Then ran our central heating system while not running the stove and disconnecting the solar heater. Ran it for 24 hrs and took the reading again... (We have dials on our meter and I have no idea what the numbers mean, but I was looking for a % ratio. I then turned off the central heat and only heated the house with the solar and rocket. The difference was 33% LESS poser consumption... (Very happy!) The solar heater was also an "experiment" like my first stove. The final solar heater for the same location will be 400% larger using an 8" (instead of 5") duct and will probably be pushing 300 to 400 CFM of heated air... That combined with the "new" rocket design, should make an even bigger difference!
=D

Totally swamped with working on this new prototype project, but it's just too hared to step back from all of this.

Did some research this morning as I didn't understand the walker riser less concept. (Not sure that I still do! LOL!) I found about 10 pages/sites with lots of info... I'll be reading them when I can to better understand the "guts" / airflow and how it works and how to adapt to Glenn's design and how to adapt it to my fireplace.

Thanks!

Richard
