GE P&W FuelSolv FS3954: Controls Ash-Clogging in an Incinerator Boiler - Manual (Page 2)

Page 2 Case Study
In the test, two injection points were placed at the
outlet of the furnace in the first riser stage of the
boiler (smoke temperature 850°C/1560°F, the mini-
mum temperature for injection being 760°C/
1400°F).
The test was conducted from December 2002 to
May 2003.
Results
The critical parameter for validating the test is the
temperature of the smoke (T5) upstream of the
superheaters. That temperature enables the opera-
tor to determine the shutdown for cleaning of the
installation. (650°C/1200°F).
Thanks to our technology, the client achieved its
primary goal: no shutdown between the two sched-
uled annual technical maintenances.
Achieving that goal enabled the operator to make
significant gains:
 Fulfill electricity-supply commitments with EDF
 No additional cost from outside treatments of
household waste
 Reduction in operating cost
