INSTABILITY IN RUGBY CEMENT KILN
THIS TIME NO FINE - WHY NOT?
HOW SAFE ARE RUGBY RESIDENTS?
Ever wondered what happens when things go wrong - as they frequently do? A typical example of a kiln being run at 9 times over the permitted emission limit for nearly an hour is shown in this Notification Schedule A Report from an "incident" on 15th September 2005. No trials of waste burning are supposed to be allowed in an unstable kiln, but the EA permitted them to start the coal and petcoke trials on 11th October, and then there was the huge pollution incident of 14/15 October during the Tyre Trials resulting in a £400,000 fine!
From the attached you see that from 14.30 to 15.15 they "estimate" that the plant ran ON AVERAGE at 458 mg/m3 instead of the maximum permitted 55 mg/m3.
This presumably takes into account the anticipated 20,000mg/m3 that occurs immediately after an ESP trip. And, so they say, at the same time 100 kilos of particulate were also emitted from the cooler and kiln inlet.
Note well that both the main ESP and the BYPASS ESP had tripped. The main ESP is to be replaced by a bag filter, but the BYPASS ESP (and CLINKER COOLER ESP) will still be there and still be subject to trips.
