Warped baffle

Warped baffle

PostBy: CoalBurner5 On: Mon Feb 04, 2013 9:46 pm

Running a df520 and realized that the baffle is warped badly. I'm assuming that I'm not running at top efficiency? so my questions are:
1 Is this something I have to replace now or can it wait?
2 How much heat am I losing?
3. How much for a new baffle?

If you lay it flat on the floor how big is the gap in the middle? 1" or so? That is pretty standard based on the units I have seen. You can replace it for peace of mind, but I doubt it will have a detectable impact on performance.

I recently did a controlled burn with the baffle in place, and then removed it and repeated the cycle...the stack temperature was 65 degrees higher - about the same as a unit that was overdue for a cleaning. (mine was squeaky clean at the time of the experiment).

Edit: You can probably locate a used (non-warped) baffle for considerably less than a new one.

If it's still hanging, don't worry about it.

why don't you reach in and turn it around so it bends the other way. :)

Worked on one that wasn't warped too bad. I had one that was really warped and it wasn't working. But then again,it wasn't getting fired as hot as it was to warp it in the first place. :) Chris is probably right anyway. It really wouldn't make that much of a difference if it was a little warped. Big difference without one though :)

Ever put one in a round-door boiler? Better have a good aim and strong shoulders.

Ever put one in a 700? Better have long gorilla arms. Can't imagine putting one in the 900 or 1300 :shock:

I put one in recently for a guy who had shoulder problems. I had one arm in the door and it was almost fully extended. I had enough strength to shove it up and amazingly it hooked. I don't know how many times I could tried that. If I do it again, I will have a pipe under it and another guy behind me to use the pipe as a lever.

I take my baffle down once per year for cleaning... and it is a stretch to get it back up there thru the round door.

Sometimes it takes me a bit to get it in the V holder and you arm gets tired quickly doing it! once a year is enough for me..

Im not sure the unit or design without pics, baffles certainly take the brunt of the heat so warping baffles is fairly common and should not effect anything to any large degree, i suppose if you just want a quick fix you could slap some refractory in the area of the "gap" to prevent draft/airflow from getting under the baffle do easily.

Can someone post a picture of the baffle, my 700 has nothing removable in it as far as I can tell, someone said the older ones were welded in.

Yeah, your baffle is welded in. I have had a couple that were like yours. they have a welded in water baffle. Great heat grabber. How's the boiler working out?
