| dc.description.abstract | In recent years, the market of alternative fuel to replace fossil fuel is growing rapidly. However, it is not easy to classify the recycling waste and control its quality. Some wastes can be used as fuel for achieving waste recycling, reducing the relying on fossil fuel and carbon dioxide emissions. This study investigates the air pollutants emitted from the co- firing process of solid recovered fuel (SRF) and waste rubber in the fluidized-bed boiler of plant A and the co-combustion process of raw coal and solid recovered fuel in the chain bed boiler of plant B. Concentrations of carbon dioxide, particulate matter, sulfur oxides, nitrogen oxides and dioxin in the flue gas emitted are measured to calculate the emission factors. The results show that the emission factor of carbon dioxide is 275 kg/ton of steam, particulate matter is 7.81 g/ton of steam, sulfur oxide is 28.64 g/ton of steam, nitrogen oxide is 51.27 g/ton of steam, and dioxin is 55.644 ng-TEQ/ton of steam. The emission factors measured for plant B are carbon dioxide: 292 g/ton of steam, particulate matter: 5.62 g/ton of steam, sulfur oxide: 21.39 g/ton of steam, nitrogen oxide: 104.65 g/ton of steam, and PCDD/F: 4.50 ng-TEQ/ton of steam. The emission factor of dioxin in plant A is 12.4 times higher than that of plant B. As 5% solid recovered fuel is added to plant B, the carbon dioxide emission factor is reduced to 248 kg/ton of steam. Although applying the solid recovered fuel can effectively reduce carbon dioxide emission, the PCDD/F emission should be well controlled. | en_US |
