| Abstract:________________________________________________ |
| The
combustion of water-fuel
oil emulsions is
presented as a method of
reducing the polluting
effects of the substances
contained in flue gases,
on the basis of 15
references.The combustion
of fuel oils, especially
of heavy fuel oil sorts,
presents more
disadvantages: (i)
difficulties of spraying,
(ii) the
risk of imperfect
combustion, (iii)
a need for the use of a
high excess air
coefficient, (iv)
formation of S, V and N
oxides.As a result of
fuel transport,
transferand storage opera-tions,
the water content may
reach up to 4...10 % , or
even more. So the
combustion process
presents disturbances.
Water removal is
difficult. It is more
efficient to turn the
water containing liquid
fuel into water-oil
emulsion By emulsion
combustion there are
advantages, as: (a)
fuel economy, (b)
decrease of environmental
pollution.The flue gases
evacuated in the
environment have got in
their composition more or
less noxious substances The
concentration shows a continuous
decrease
with the
increasing water content
(W, %) : linear,
exponential or even with
a slight minimum,
according to references. |

A
"flue gas toxicity
coefficient"-
(CT)
-
shall
take into account:
-
nitrogen oxides (CNOx,
x100 mg/m3);
- soot (CC,
x100 mg/m3);
-
carbon monoxide (CCO,
x100 mg/m3)
concentration.

By the
combustion of fuel oils there has
been reported thepresence of
organic compounds as well.
Benzopyrene is known like a
cancer-causing substance. In case
of an emulsion with
19-22 % water the benzopyrene
content has lowered with 70 %,
contrary to ordinary combustion
of heavy fuel oils.
From
all the data results presented
the combustion of
water-fuel oil emulsions has very
positive effects concerning the
reduction of the pollution of our
environment.
