Abstract

This study presents the design and performance analysis of a producer gas cleaning system for a downdraft gasifier used to process Segregated Dry Municipal Solid Waste (SDMSW) and biomass. The cleaning system is critical to remove impurities such as particulate matter, tars, and other pollutants from the producer gas, which can negatively impact the efficiency and longevity of the gasifier, as well as damage downstream equipment. The cleaning system was designed to include several stages, such as mechanical filtration, adsorption, and catalytic oxidation. The performance of the cleaning system was evaluated using a combination of SDMSW and biomass as feedstock, and the results showed that the cleaning system was able to effectively remove impurities from the producer gas, resulting in an improvement in the efficiency and longevity of the downdraft gasifier. This study provides valuable insights for the optimization of downdraft gasifier systems using SDMSW and biomass as feedstock, and highlights the importance of an effective producer gas cleaning system in the overall performance and cost-effectiveness of this technology. The gas cleaning system was utilized to test the producer gas by gas chromatography. Results from the analysis show a mass flow of 783 kg/hr, a lower heating value of 4.58 MJ/Nm3, a specific heat of 1.11 kJ/kg K, and a cold gas efficiency of 79.7%. Additionally, the system was able to reduce tar and ash by 50 kg/hr and 5.5 kg/hr respectively.
