The 4' x 8'stainless Steel, stngle,vvell-mounted canopy hood was modified toad as a <br /> dedicated hood to ensure total effluent capture. The mouth of th6 30"x 8"duct vmz reduced to <br /> an$" x 8" square to match the velocity fQr Isokinetic sampling and to fully contVn the natural <br /> pl=e(Figure 2). <br /> • � l <br /> 1� <br /> Figure 2: The$a" x 8" duct reduced to 8"'x 8'Square. <br /> $Unless-steel panels extended the ductwork from the 8'"x S"square;rnauth to ft wict of the <br /> oven. Side panels affixed to the duct extensions,the back wall and the metal table,on which the <br /> oven sits, pro%tided endosure to all sides of the overt, except the fm nt face. To prewnt eftkmt <br /> escape during the loadingfm <br /> and unloading process m the front fake, an additiinal patael was <br /> extended from the hood to the tap edge of the oven,leaving only enough room for opermtig and <br /> dosing the oven door(Figure 3). Effluent was sampled across the 8"x 8"square duct opening <br /> with the probe nuzzle directed upstream. <br /> DRAJr'r 6rz 1199 <br />
