Hello everyone
Hope all are well.
I need help. My rocket mass heater suddenly has smock again. Look at this, why?



Also, I want to present my solar food dehydrator. I learn from Erica's, but hers is so complicated, need to use the electric saw to cut woods, so I alter the idea into use plastic barrel and ducts. However, I don't see the wind come into the barrel. This is the same idea as RMH. Hope you can help me. I put my hand on the top chimny and see no air flow. How do I get air to come into the barrel to dry my food. Please help

I found many of these worms in my soil. I grow vegetable in 5 gallon bucket. Yesterday I found many of this kind of worm in my bucket of soil. Are these worms good or bad for my plant. Would they come out of soil and worm up to my plants eat them?

Life is back to normal again. The flame and smoke (if any) know which direction to go, which is the burn turnnel, and they go directly to that direction, no more wondering around like lost soul doesn't know where to go and then go up the feed tube, horri... horri... ble

By your advice, I did flip the T yesterday, but the problem is my cob bench is very long 12 feet and I have only 2-3 feet of space at the end of the bench to the wall. I tried the extendable stick, but the max of the stick is still only 8 feet. So 4 feet can’t be accessed to. This time is good because I broke the bench so I have access to it. But next year I don’t want to break the bench again. 4 feet not cleaning is a lot to cause problem. As you have said only one object fall into the duct enough to cause problem. So I finally bought another T. I found a flimsy T at Home Depot. It’s kinda small so it fits in the space.

But I found out an issue. I think this is the reason cause my RMH to have problem:

Before I had this RMH, I used a conventional wood stove heater for 1 year. Because the high heat went directly from the stove to the duct out the exhaust with out going through the cob bench, made the duct deteriorated. I used that same duct in the same place as my vertical duct for my RMH. Yesterday I saw this vertical duct had a hole, big one, 2X4 inchies, right inside the CH. That’s why the CH was so smoky, and my dad keeps burning little … The old duct I used only one more year compare to other ducts. That old one was worn out terriblely compare to other ducts. So the old one is 2 years in service and the new is one year in service, yet the old duct and the new duct of one year apart look like a 70 grandma and a 13 years old little teenager. Hight heat of the conventional wood stove done terrible to the duct.

What kind of effect would that big hole in the vertical duct done to my RMH?

The place I cant reach is the new extention with the elbow. What do you think if I take out the elbow, put a 1feet duct in it and put cob around, I turn the duct so it won't stay put, when it dry out some what, I will pull the duct out so I can have a new clean out (for cleanning purpose), and I will put a cap there seal off. so that spot will not have duct but it has a clean out. The spot is too tight to put another T like the other end. It doesn't work so I have it bare with no duct. Would that work?

I do have a lot of soot. The kind of soot which hanging down like bunch of messy hair stick together into little bunch, around 1 inches long. Enclosed is the picture I took from one of my duct when clean out. So, I have to clean out all of my ducts? You mean these soots cause burn back and smoke? But why do I have soots now? Last time I clean out after 1 season of hard burn and it is much better than this, no soot. Just one month since my last clean out and this time it was horrible with soot

you are right about the extension. One last part of the duct I can't clean out, but I can put the hose of the shop vac in there and try my best.
The duct as a manifold sticks into the barrel was my original version. My RMH gone through a lot of "new model". I no longer have that kind of manifold. Mine is the hand made big manifold. My RMH is kind a "Intel Core i8" now. I mean went through a few times of upgrade and better model

I have a lid and I already opened it this morning. The heat riser is in tact and good. I have fired bricks for my heat riser. Except that it was so dirty. I forgot to take picture of it.

This year it is not that cold, but my dad likes to burn, so he burns a little bit, not a full feed tube, half a feed tube for couple of hours, since mid-Oct until now. I think it's not hot enough to burn all the inside so black black dirty. The heat riser has layer of black didn't see before. Before it had some white ashes cover the yellow fired brick, this time I opened it, it was black and dirty, I had to have something to scrape it.

But my RMH was fine until one week now the flame started to dance like lost soul doens't knnow what direction to go, think my RMH have no draft. So the flame dance around weakly and burn up, sending black smoke

What's wrong?

I am in big trouble, I need help please

The video I posted after fixing my clean outs, look pretty good. My burning is reasonable running into the burn tunnel and no smoke even my redo portion was still wet. Now my RMH totally burns up and smoke up, black smoke all over the green house. What's going wrong. Please give me advise, what would cause this burn up and smoke up, and how do I fix it please
