I understand that increasing stack height, flue gas temperature and difference in air density all increase draft. My question is that would your double barrels not increase flue gas friction by fighting the overall stack height outside the greenhouse? I love your page you have done an awesome job.Iannoreply@blogger.comtag:blogger.com,1999:blog-2976195011490524027.post-46765082361223518602012-01-13T19:50:08.743-05:002012-01-13T19:50:08.743-05:00This weekend, I'm going to try a small duct fa...This weekend, I'm going to try a small duct fan inside the exhaust to get the draft started. I got it started last weekend, but had a lot of smoke. ;-) I think it should work very well.Web4Debhttps://www.blogger.com/profile/12255603822140216725noreply@blogger.comtag:blogger.com,1999:blog-2976195011490524027.post-67172472169822309322012-01-13T19:39:44.185-05:002012-01-13T19:39:44.185-05:00Very nice series Rob, Looking forward to each addi...Very nice series Rob, Looking forward to each addition you post.<br />I was wondering about the difficulty you might have starting the draft. Have you considered a propane torch for a preheater? Use the gas valve assembly from an old furnace and a 5 gal propane bottle and run it for 15 seconds or so prior to your pellet auger starting up. It could be an over-sized pellet ignition system that serves as a preheater to get the draft started.<br /><br />Thanks a lot for taking the time and effort to post the videos man.<br /><br />Appreciated!<br /><br />EricErichttps://www.blogger.com/profile/17343492831397053341noreply@blogger.comtag:blogger.com,1999:blog-2976195011490524027.post-89714436835156608852012-01-11T11:36:48.165-05:002012-01-11T11:36:48.165-05:00I'll do more detail when I get around to the v...I'll do more detail when I get around to the video. I stacked the barrels because I wanted to see if I could get a stronger draft with a taller chimney...which I did. I'm hoping to just need the heater for about 2 months. I have no idea how long they will last. I would assume the top lid will go first since that takes the most heat.Web4Debhttps://www.blogger.com/profile/12255603822140216725noreply@blogger.comtag:blogger.com,1999:blog-2976195011490524027.post-79868957580335792402012-01-11T11:30:50.288-05:002012-01-11T11:30:50.288-05:00Hey Rob, great job documenting your work, as usual...Hey Rob, great job documenting your work, as usual. A few questions...did you stack the barrels because of the height of the dome? How many months of the year do you expect to run the heater? How often will you need to replace those barrels, if ever? <br /><br />ChrisChrishttps://www.blogger.com/profile/17350295661370595875noreply@blogger.com
