THE REDUCTION IN EMISSIONS OF SOOT AND INCRUSTED RESIDUES IN STEAM BOILERS RUNNING ON FUEL OIL.

IMPROVEMENTS OBTAINED IN A PLANT WITH TWO BOILERS OF 25 TM/H WHEN
TREATING THE FUEL OIL WITH THE ADDITIVE "rb bertomeu" beco F2/A

A steam generation installation, consisting of two boilers with an steam output of 25 Tm/h, both running on fuel oil, used to cause a problematic situation in relation to its surroundings, because on occasions it emitted soot along with the combustion gases released through the chimneys, giving rise to complaints from buildings in the immediate vicinity and surrounding area. The pyro-tubular boilers are equipped with a double burner operating at single speed or double speed, according to production requirements.

To find a permanent solution to the problem, a three-month test was carried out, applying the additive "rb bertomeu" beco F2/A for fuel oil used in boilers, then later, continuous additive treatment was applied when the consistent excellent results had been observed. The tests began in October 2003, and, recently, after two years of regular use of the additive, the proven results not only include significantly reduced soot emissions, putting an end to past complaints, but also, a large reduction in the usual incrusted residues on the heat exchangers and the virtual absence of coking on burners. Furthermore, heat exchangers are cleaned with greater ease and speed because the encrusted residues are more powdery and much less adhered to the tubes.

The improvements obtained in these parameters are estimated to correspond approximately to the following values:

Reduction in soot emissions per chimney

:

75-85 %

Reduction in quantity of residues in the heat exchangers

:

70-80 %

Reduction in the time needed for each cleaning operation

:

reduced by 50-70 %

Reduction in cleaning burners affected by coking

:

70-90 %

The reduction in ‘operational incidents’ with treatment applied to the fuel oil (additive applied at a dosage of 0.4-0.5 parts per thousand with "rb bertomeu" beco F2/A) has allowed the factory to eradicate the problem of troublesome emissions, to reduce stoppages for cleaning, and to increase steam production in proportion. This ensures the profitability of the additive treatment, even without taking into consideration other benefits. The improvements obtained are consistent with results obtained in other plants with steam boilers.
