  1. 78SS, Many thanks for the WC test, I am not sure why the blower is rated in oz. of static pressure, but it is good to know what the real water column number is. Thanks again to all the feedback from everyone. Storm
  2. 78, As I said in my original post, I am not sure of this calculation, but I would be interested to know.. give it a try and let us know what your blower will do wide open? I have talked with several people about this. and I wouldn't be at all surprised if it did blow bubbles 6 ft. down. Storm
  3. I tried to post this in thread, but keep getting forbidden. sigh. As an update on the blower issue, I have done some more research, talked with one of the engineers that I work with that has done air balancing on ovens, and have come up with some helpful information. I contacted Kayne and sons about the blowers they have, which by the way will do the job in SPADES. The one piece of nomenclature that seems out of place is the way these blowers are rated with regard to static pressure. Static pressure should be rated in inches of water column. So the rating of the blowers in ounces of static pressure is deceptive. They did reply to my inquiry and stated that the manufacturer rated them that way. After 78sharpshooter posted his comment about having to choke his blower down so far, got me thinking about the nomenclature issue with the rating. I think the sp listed can be converted directly to PSI, and that in turn can be converted to water column. going on that premise, the large 164 CFM blower that 78ss has would have 2.5 lbs. PSI of output, that would translate to about 70 inches of water column pressure, which would explain why he has to choke it down so much, if the requirement of a ribbon burner is a minimum of 5 and 7.5 works better, then the wide open 70 that is available will totally exceed the requirement. On a side note, because of the way centrifugal blowers are choked with the inlet being partially ( or mostly ) covered, the motor doesn't have to work as hard, because the impeller is spinning in a negative environment. The reason this works is because the motor doesn't rely on the impeller for air circulation, it has it's own fan for that. As you can see, this is why speed controls don't work well with this type of blower, the motor can't get proper cooling at the lower speeds / higher current that use of a speed control will cause. If anyone has more knowledge about this than I do, please weigh in. These are conclusions I have reached through my research and from the real world experience with this set-up that 78ss presented in his post. Thanks! Storm
  4. I know this late to the discussion, but Frosty and Charlotte, thank you for weighing in on the amount of insulation, and the information about how each performs. This was EXTREMELY helpful. I also think is great that you "cough cough" encourage people to work things out for themselves, rather than spoon feeding them. I think it makes for a better knowledge of the "machine" (in this case - forge ) as well as a better understanding of WHY things are the way they are, rather than just shrugging and not digging deeper. Storm
  5. Thank you all for the replies! From what I have been able to determine, ( and it has been stated here and in other posts ) is to keep the air/fuel mixture velocity in the ribbon burner higher than the speed of the flame front travel back through the ribbon burner, as long as this balance is maintained, then there should never be combustion on the wrong ( manifold ) side of the burner. 78SharpShooter, Thank you so much for the observed performance of your forge and blower combination. Storm
  6. Can anyone recommend a cost effective blower that could be used with a ribbon burner? I know that most require 5 lbs. of static pressure. I also know that blowers are available from some of the blacksmith supply houses. But I would like to find a suitable alternative that didn't cost $140 per copy at the start. Like everyone I want to walk the line between spending what is necessary and not over spending. From my research, it seems I would be looking for a centrifugal blower, that has the necessary sp to run the ribbon burner. Can anyone make some recommendations on where they have sourced alternative blowers from and what type of equipment they were aquired from? Thanks, Storm
