Data analysis of the flue gas emissions in the thermal-power plant firing fuel oil and natural gas|
Nakomcic-Smaragdakis, B.; Cepic, Z.; Cepic, M. & Stajic, T.
The thermal-power plant with combined heat
and power (CHP) production located in the city of Zrenjanin
(Serbia) is powered by two steam boilers with nominal
power of 280 MW each. Considering the problem of
increasing pollutant emissions that occur during fossil-fuel
combustion process, which is recognized as an arising
problem in the CHP Zrenjanin, the accredited Laboratory
has been carrying out monitoring and control of the
emission production. The emissions have been measured
during winter season on boiler B1 for five working regimes
of burners, by adjusting the fuel ratio between natural gas
and fuel oil. The measurement has been done regarding
carbon monoxide, sulphur dioxide, nitrogen oxides (NOx),
particulate matter (PM), gaseous inorganic chlorine compounds
denoted as hydrogen chloride, and gaseous inorganic
fluoride compounds denoted as hydrogen fluoride.
Data acquired from those measurements have shown that
all parameters except NOx and PM did not exceed emission
limits defined under current regulatory statute.
According to data analysis of the flue gas emissions, first
preventive actions are recommended, then possible actions
that could be taken during combustion process, and as last
but not least, actions that have to be applied in case
when emission problems appears. Regarding CHP control
and management problems, some advices are given
emphasizing an integral approach to the analysis and
optimization of the CHP as the best solution.
