Operators of many ferrous and non –ferrous foundry processes have
made significant environmental improvements in recent years fitting high
performance fabric filter dust collectors (bagfilters) to furnace, cupula,
shotblasting, sand cleaning and finishing processes. Emissions from such
processes are highly abated only when bagfilters operate to their design
condition, and therefore the current issue is how to effectively monitor the
condition of the bagfilter to ensure it is operating to design conditions and
demonstrating, on an ongoing basis, that particulate emissions are below
legislative limits.
This paper focuses on how Electrodynamic type particulate monitors are
used by foundries in the UK, Germany, Japan, and US to continuously
monitor the performance of bagfilters as well as help maintenance
personnel diagnose the location of leaking or faulty bag rows hence
reducing re-bagging costs. It also covers how such monitoring satisfies
environmental legislative requirements resulting from PPC (UK), IPC
(Europe) and MACT (US) as well as improves environmental performance.
