Spurred by the discussion of wood firing and kiln construction in populated areas, I took a little time to look at my own city code and some Environmental Protection Agency (E.P.A.) documents.
Our city code is fairly restrictive about "wood burning appliances" used for space heating or for "aesthetic" purposes. It exempts those used primarily for food preparation. It does not mention a "kiln".
I checked with the building department of our small city and would not need a permit to add a wood burning fireplace outside our house, as might be intended for a barbecue. The exception is if the chimney were over a certain height, I think 12 ft. That point appears to be a safety issue, not one of air pollution.
I then looked at the E.P.A. document on wood stoves. For those interested, it is at http://www.epa.gov/ttn/chief/ap42/ch01/related/woodstove.pdf
The most interesting information here was that the newer designed wood stoves are almost as efficient in reducing particulate pollution as a new or "well maintained" $$ catalytic type. There is a good chart on the various types measuring lbs of pollution per ton of fuel...grams/kilo for those in the modern global economy.
E.P.A. tests indicated the efficiency of even the new stoves deteriorates over time due to the "high heat" which eventually destroys the baffles.
