Nitrated Phenols and PM2.5 Reduction of High-Sodium Coal Combustion by Diatomite Addition in a Typical Residential Stove
نویسندگان
چکیده
Nitrated phenols from residential combustion aggravate the greenhouse effect and endanger human health. To search for an ideal fuel which produces low nitrated phenols, high-sodium coal, conventionally used in coal-fired power plants, has been considering that construction of civil stoves makes it easy to deal with slag fouling. In this study, we investigated pollutant emissions by comparing those produced Jinyu coal 5% diatomite. It was found mixed diatomite showed most desirable emission factors (EFs) particle matter (PM) EFs. Originally, generated more PM EFs because its easily vaporized composition sodium (Na) derived Na compounds condensation nuclei particles. PM2.5 were as high 3.23 ± 0.11 mg/kJ, 11% than Jingyu coal. However, had lower whose phenol 2.3 0.2 mg/MJ, remarkably (4.0 0.4 mg/MJ). This can be explained fact less intermediate NOx generation. after dropped 60.9% 53.3%, respectively, during process. Its abundant silicon (Si) aluminum (Al) formed a high-melting-point substance Na. Consequently, considerable reduction efficiency promotion both achieved addition concluded is promising alternative domestic featuring excellent effects, easy-to-handle slagging stoves.
