| Popis: | Municipal solid waste (MSW) contains a significant amount of paper, food waste, wood and yard trimmings, cotton, and leather and is considered as a source of renewable energy. Energy could be recovered from MSW through gasification technology. Gasification experiments were conducted in a pilot-scale plant (8 ton/day) using solid refuse fuel (SRF). SRF was produced from MSW by mechanical biological treatment process consisting of crushing, sorting, and drying. Gasification pilot plant is equipped with various control systems of cyclone, scrubber, wet electric precipitator, and moisture remover for reducing gaseous pollutants and tar. Gaseous pollutants such as NH3, HCN, and HCl were sampled at inlet and outlet locations of these control units to analyse the concentrations of pollutants with checking their removal efficiencies. Korean standard methods were used for sampling gaseous pollutants. Concentrations of most gaseous pollutants were reduced by control systems. Specially, removal efficiency of wet electric precipitator was the highest in all cleaning systems, and we could calculate the conversion rate of gaseous pollutants. From analysing above results, we can conclude that this gasification plant is good in operation and the research team is now designing a scale-up plant for commercialization. |
