Wout = mass emission rate of POHC in the stack prior to the release to the air.
8. The average dioxin and furan concentration in the emissions should not exceed 80ng/m3 total dioxins and furans if measured for a period of 6 to 16 hours.
Note:

6 Chimney / Stack 1. The chimney should have a minimum height of 10 meters above ground level and clear the maximum point of the building by not less than 3 meters for all roofs. The topography and height of adjacent buildings within 50 meters radius should be taken into consideration. If possible the chimney needs to be visible to the operator from the feeding area.
3. Whenever the preceding charge hasn’t been completely combusted in the case of batch feeding.
