9 Site G

9.1 Introduction

Sampling was carried out at Site G on 26 and 27 March 2003. Samples were collected from the induction furnace baghouse discharge to determine the concentration and mass emission of PCDD and PCDF present in the gases discharged to the atmosphere.

The sampling ports were after the baghouse and were at least 5 stack diameters from any disturbance to the flow.

Details of the sampling date, times and stack dimensions are:

  • Sample date and time:
    • Sample 1: 26 March 2003, 9:42-14:46
    • Sample 2: 27 March 2003, 6:32-10:00
  • Stack dimensions: 0.575 metre diameter circular duct.
