摘要	Plasma gasification technology has been demonstrated as one of the state of the art and environmentally friendly technologies for the treatment of municipal solid waste (MSW), due to its large volume reduction ratio, high generation efficiency and extremely low emission of secondary pollutants. This work aims to calculate and optimize process parameters for the demo plant of MSW plasma gasification in Beijing which has been made by the Institute of Mechanics, Chinese Academy of Sciences (IMECH, CAS). Duration time of the MSW in the reaction section is beyond 5 seconds, so equilibrium assumption is efficient to simulate gasification processes. Furthermore, a simplified chemical reaction model is develop that can be used to predict concentration distribution of syngas under different operating parameters including gasification temperature, excess air ratio, feeding rate and moisture content. When doing optimum design, two types of constraint conditions are considered, including: 1) fixing ratio of CO to H2 equal to 0.8, 0.9 and 1.0, respectively, corresponding optimum object is plasma torch and heating value of syngas; 2) fixing plasma torch power to 900 kW, corresponding optimum object is compositions and heating value of Syngas. The calculation results show that product distribution is strongly affected by moisture content and gasification temperature (<1,200 K). Although the equilibrium models do not represent the reactions that occur at relatively high temperatures (&asyum;1,273 K) very well, these models can be useful to show some tendencies on the working parameter variations of a gasifier.
