FuelSolv* FS3954: Controls Ash-Clogging
in an Incinerator Boiler

Setting up a FuelSolv FS3954 treatment program on a 7
ton/hour household waste incinerator that produces electricity
for EDF and heats horticultural greenhouses

Challenge

During its winter season, a household waste incin-
erator faces many shutdowns due to the accumula-
tion of deposits on the boiler’s exchange surfaces.
As a result of that reduction in heat exchange, the
limit temperature acceptable for the first super-
heater is reached quickly.

Several shutdowns are necessary during the season
(5 months) for a quick cleaning of the smoke path-
ways, i.e. one shutdown about every six weeks.
Those shutdowns cause operating losses:



Treatment of household waste at an outside
site (transfer cost)



EDF penalty for not supplying electricity



Outside servicing costs

Solution

GE Water & Process Technologies offers an expan-
sive FuelSolv FS3954 treatment that limits boiler
clogging to reduce the number of shutdowns for
cleaning over the course of the season.

A laboratory study of vitrification tests was done on
ashes from stages 2 and 3 of the boiler. Those tests
show the effect of FuelSolv FS3954 for a dosing
greater than 2% with respect to ash at a tempera-
ture of 750°C/1380°F).

White 1% 2% 4%

Due to the rate of ash generated by household
waste, we recommend a dosing of 500 g of FuelSolv
FS3954/ton of waste incinerated.

FuelSolv FS3954 comes in the form of non-
hygroscopic particles that can be injected into the
boiler using a compressed-air doser.
