Background: The content of nitrogen and carbon oxides produced by
the combustion of solid or liquid fuels in the source flue gases is a serious
environmental threat. Flue gas cleaning is still an urgent problem that needs a
solution. Because of our development, it is possible to offer a flue
gas-cleaning device for sulfur, nitrogen and carbon oxides.
Aims: The study was conducted to explore one of the potential
methods to purify exhaust gases from dangerous chemical compounds and to prove
the efficiency of the study method.
Methodology: The study was based partly on experimental modelling
of the device and using data from it, a mathematical model for the general
solution. The study was conducted between 2014 and 2017 at the National Academy
of Food Technology faculty of Refrigerating Machines Plant and Air Conditioning
in Odesa, Ukraine. An experimental unit was built in the laboratory to conduct
a set of experiments with measurements of temperature, pressure and speed of
flow of specially prepared air mix with added pollutants.
Results: The results of the study demonstrate that the proposed
flue gas purification device effectively reduces the concentrations of harmful
pollutants such as sulfur oxides (SOx), nitrogen oxides (NOx), and carbon
monoxide (CO) in flue gases. Moreover, the temperature drop of the air mix flow
that lies within the estimated boundaries was calculated. That leads to a drop
of condensing pollutant from the air flow and accumulating in a special
gathering chamber, and leads to a purifying rate of 70-80%.
Conclusion: In conclusion, the results indicate that the proposed
device represents a significant improvement in the field of flue gas
purification. Using a created heat exchanger filter, it is possible to clear
flue gases from almost all polluting factors. In the initial boiler operating
modes, when the highest amount of carcinogens is released, the filter can be
used to condense them. When the boiler enters the basic operating mode and the
carcinogens decompose from high temperature into simple, non-harmful
components, oxides become the main problem in the flue gas, which can also be
cleaned with our ejector filter. Future work will focus on refining the system
to further enhance its efficiency and explore its scalability for larger
industrial applications.
