Abstract
The paper gives a brief assessment of the existing methods of purification of flue gases from nitrogen oxides and carbon dioxide. To improve the environmental safety of the heat source is proposed to consider it not only as a source of heat, but also as a chemical reactor capable of producing chemical products. Given example of innovative technical solutions for the treatment and disposal of flue gases with the release of carbon dioxide as a commercial product (RF patent â„–2371238, 2009) and given an approximate economic calculation for the implementation of this decision for the boiler capacity of 20 tons of steam per hour, running on natural gas, the average consumption of flue gases V=20000 m3/h and an average initial concentration of NOx=3·10–4 % RPM and СО2=10% RPM. With the average efficiency of flue gas treatment of NOx and СО2 equal 70%. Accordingly, if the time of the boiler in the year, Тset=8000 hours, the number of captured and recycled, ÐœNOx=40 tons/year, of carbon dioxide, МСО2= 22400 tons/year. It is shown that at current prices for produced with help heat generator heat and commercial carbon dioxide economic effect of the carbon dioxide is 3.5 times higher than the effect of the realization heat and, thus, there is a real opportunity to improve the economic efficiency of the heat generator by increasing its ecological security in the use innovative technical solutions for flue gas cleaning.
