Soot-fire accidents in exhaust
gas economizers (EGE) after diesel engines represent a major
risk – not so
much because of an accident’s likelihood, but
due to the potential damage. Various factors such as
heat
transfer, soot deposit, soot calorific value, and flue
gas velocity contribute to the start of a soot-fire.
Such a fire may develop in three steps:
1. Soot burning and heat accumulation
2. Steam build-up and loss of heat exchange
3. High temperature oxidation of surfaces and break down
of the EGE.How to prevent this worrying and costly scenario?
The
answer
is simple: keep the economizer reasonably clean and secure
adequate water circulation at all times. This is easier said
than done. With
the SBS5xxx EGE Monitor you provide your crew with a decisive
tool to do the task. The SBS5xxx EGE Monitor continuously
measures inlet and outlet temperatures in relation to the
engine load.
This allows for a dynamic monitoring of the boiler’s
function.
