preheated over the fire air in a D.S.1600 for Bit coal

PostBy: slinger100 On: Sun Jan 05, 2014 6:52 pm

Hello. I added some preheated over the fire air for burning Bit coal in my D.S. 1600. I used 3"x1.5" box tubing welding an upside down u shape. the legs are 13" and the width is 15.5" there is a series of holes across the horizontal section for the air to exit. the air comes up through the legs which sit on the grate. the burning fuel bed heats the air before it exits above the fire. It is working very well as you can see in the picture. Matt

I'm new to all of this, I don't even know what bit coal is.

yes its the 8 holes that it looks like fire is coming out of them. That is the preheated oxygen burning off the volitiles (smoke).

Cool!
Is the preheated air producing flames through the whole burn cycle or just at the beginning when most of the volatile matter is burning off?

Rockwood. no it mostly looks like that for the first part of the burn. After that it burns more like Ant. coal. Lightning, no I didn't see that. How do You like the way it operates now?

I did this a number of years ago when I was playing with hand-fired bit stoves, started first with some sch 40 SS pipe and then hollow baffles w/ small holes drilled in them. It is very effective with bituminous coal. Even after the volatiles have flared, a bit of overfire air keeps the CO from the bed of coke burning completely.

The D.S. 1600 has some over the fire air already engineered into it but it is not preheated. Preheating the oxygen seems to make a lot of difference as you can see in the picture that the volatiles are being ignited from the preheated oxygen (rear of the stove) and not from the non preheated air (front of the stove).

It's likely the gases are going up instead of moving forward.

Have you looked into the anti puffback louvers for the DS machine stoves I think forum member I'm On Fire installed them on his stove.

I did see them on this forum. I wanted to try to distribute the air more evenly across the fuel bed somewhat like the Florence hot blast were designed to do 100 or so years ago.
