Abstract
This paper focuses on easing the self-regulation of nitrogen oxides (NOx) as a method for improving the efficiency of power generation in MSW incinerators. It shows about degree of impact to the surrounding environment, due to differences in NOx emission levels, the improvement of power generation and the reduction of green house gas.
With recent advances in MSW combustion technology, it is expected that the NOx concentration in exhaust emissions will reach between 100 to 120 ppm, without selective catalytic reactor (SCR). Here, we simply simulated the atmospheric diffusion of NOx at about a dozen of planned plants that were randomly selected for the experiment. Our results showed that the environmental concentration of NOx, calculated using emission that does not employ SCR, is about 1-4% higher than the environmental standards of those that do employ SCR. In addition, the amount of power generated when the self-imposed restraint value was eased from 50 to 120ppm was calculated. This appears to correspond to the carbon dioxide reduction level of 1237ton⁄year, which correlates to an expected increase of 2205MWh⁄year at the MSW incinerators using 150ton⁄day×2 furnaces scale.
