Methods 
The method of testing nitrogen content of fuel oil 
Nitrogen content of fuel oil and technological fuel 
gas is determined according to the methodology and in-
strumentation mentioned in the literature [7, p.1]
The method of testing sulfur content of fuel oil
Standard test method is used to define sulfur content 
of fuel oil [8, p.1]. The determination of sulfur content 
of technological fuel gas is not needed as it is treated 
with diethanolamine before the combustion.
The method of predicting flue gas composition 
Information system was created to calculate for pre-
dicting the composition of flue gas derived from after 
combustion of fuel oil and technological gases. It was 
performed by means of Excel [9, p.620]. The infor-
mation system was given as an electronic appendix to 
this paper.

Results and discussion 
Prediction process of flue gas composition.
Firstly, created an information system that calcu-
lates the material balance of the process of combustion 
of the primary technological furnace, where fuel oil and 
technological fuel gases are combusted, on the techno-
logical installation ELOU-AVT-2/3 of Fergana Refin-
ery. At the same time, using standard methods for deter-
mining the composition of fuels, it was possible to de-
termine the amount of nitrogen and sulfur and predict 
the amount of toxic anhydrides released during combus-
tion. If the emissions of toxic and greenhouse gases are 
higher than the norm (maximum allowable emissions), 
the system indicates it (colored red for SO
2
, brown for 
NO, green for NO
2
see electronic application or Table 
2). The highest efficiency of the furnaces of primary oil 
refinery could be achieved by optimization just until 
70.68% [10, p.105]. For further increment of the effi-
ciency technological additions has to be implemented 
[6, p.60; 11, p.34]. The technological schemes for the 
process are referred as Figure 1 and Figure 2.
