Any wood burning appliance is going to produce fly ash and particles coming out the chimney which I think is mostly the elements in wood (minerals) that just can't be broken down any further. So unless your standing close to a chimney pipe and breathing in the exhaust on a continuous basis, I don't think there is any huge risk for most healthy people to be concerned with.

Maybe you can get some wind protection boards to make smaller cooking "room" outside? Atleast on some directions.
Metal is going to last long I guess.. I have read it so many times on this forum. Since almost every body tries it at first.

So, without insulation the riser isn't getting hot enough and you're getting smoke.
