<body class='hmmessage'><div dir='ltr'>I have enjoyed the information exchange on emissions control from wood burning stoves from everyone. In a previous life, I designed burners for the combustion of hazardous organic wastes and used the 3 T's as my design guide - time, temperature and turbulence. The gases were combusted to reach a sufficiently high <u>temperature</u> (1200 - 2000 degrees F) at a flow velocity of 20 - 40 ft/second to create <u>turbulence</u> and maintained at the temperature for .75 to 1 second (<u>TIME</u>).<BR> <BR>This information can be reviewed in an EPA Document on the combustion of VOC's at: <a href="http://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=5&ved=0CEEQFjAE&url=http%3A%2F%2Fwww.epa.gov%2Fttn%2Fcaaa%2Ft1%2Freports%2Fsect5-5.pdf&ei=Txi_UoEUkemgBKf1goAE&usg=AFQjCNGf4e4RAD3Cv2PlP2gS3Rg0XV-mCg">http://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=5&ved=0CEEQFjAE&url=http%3A%2F%2Fwww.epa.gov%2Fttn%2Fcaaa%2Ft1%2Freports%2Fsect5-5.pdf&ei=Txi_UoEUkemgBKf1goAE&usg=AFQjCNGf4e4RAD3Cv2PlP2gS3Rg0XV-mCg</a><BR> <BR>Thank you.<br><br>Art Krenzel, P.E.<br>PHOENIX TECHNOLOGIES<br>10505 NE 285th Street<br>Battle Ground, WA 98604<br> <br><font face="Times New Roman">
