ABSTRACT
The energy produced through biomass, a bio-organism, is called bioenergy. Recently, the amount of biogas generated from food waste is increased, and the development of technology to deal with food waste urgent. The main ingredient fermented from food waste is more than 60% of methane, and the generation of electricity generated by using cogeneration as fuel is more than 35% of total energy. However, the amount of NOx generated in the exhaust gas discharged from the power plant using biogas is increased significantly, and a technology for reducing the amount of emission is needed. By applying De-NOx system (SCR) applied to the vehicle, the existing diesel generator was concerted and applied to the generator for bioenergy. As NOx increases, the amount of emissions increases and the temperature of the exhaust gas increases. Especially, NOx is more exhausted and the exhaust gas temperature increases as the exhaust volume increases and in order to improve the purification efficiency, an apparatus for controlling the exhaust gas temperature is required to increase the optimal purification efficiency. This paper aims to develop a technology to improve NOx reduction efficiency when applying SCR to reduce NOx generated by using methane gas in biogas engine.
