Thanks SWPaDon... interesting thread on stove restoration and the Rosemont design is an option.
UPDATE: I ran the stove last night with the new manometer hooked up and was somewhat surprised. Bottom line it appears that the draft is not a problem but only 20# was used for the test. Here are the draft readings
While starting the stove -- only 20# of Coal
Bottom air open slightly
.06 -.07 -- MPD wide open Baro in operation
.14 -.17 -- MPD wide open with Baro held shut
Stack temps 275-325 based on magnetic thermometer
Once the stove was up and running / volatiles burned off / all coal up and at peak of burn
Bottom air completely closed
.04-.05 -- MPD wide open with Baro wide open
.05 -- MPD closed with Baro wide open--- this was interesting that MPD did not affect it much
.1 -- MPD closed and Baro held closed
Stack temps were running 600
Did not check the stove during the late part of the burn... fell asleep.
Hence the correct draft does not seem to lower the temps to 300- 400 as thought-- I did not hold it with higher draft for long so I can not attest to higher stack temps with higher draft but would thing that would
I plan on running this test again tonight logging the draft and taking stack temps with IR thermometer to make sure the thermometer is not incorrect. Also going to add more coal to check temps and draft since want this stove to be able to handle larger amounts to decrease loading frequency.
