I ma making a rocket stove J - using fire bricks.
This is for heating water for bathing in a pot
I am doing this in two steps -
First step (is where I am) we made the basic rocket stove stacking the fire bricks, test it, make any changes if required.
After rectification i will add Cob insulation around the firebricks and around the pot too. The heat riser will continue around the pot and then via a chimney the exhaust will be let out.
We built the rocket stove using 65 firebricks of 9x4.5x2 inches size
Various dimensions are shown in pic below (all dimensions are internal). Pl note the pot and its insulation will have gap around it - to function a further heat riser.
See photos of our test construction and test fire here
The heat we are generating feels less - what could be the reasons?
Fair amount of smoke comes out of the heat riser - its not smoke less - why?
The wood sticks do not keep going inside (gravity feed) - rather some of them just stopped burning after 30min or fell inside and stopped burning
We see fair amount of ash - what could be the reason for that?
Also we found it was not easy to start the fire - the fire kept coming out of the feed chamber only inside of going into the burn tunnel?
