Description

technical field [0001] The invention relates to the technical field of municipal solid waste incineration, in particular to a key process parameter analysis method based on multi-software coupling simulation MSWI process. Background technique [0002] The generation of municipal solid wastes (MSW) is increasing with the improvement of economic development level and the acceleration of urbanization. MSW incineration (MSW incineration, MSWI) technology is widely used in the world due to its advantages of harmlessness, reduction and resource utilization. However, if the control strategy is not appropriate, it is easy to cause nitrogen oxides, SO 2 And the discharge concentration of pollutants such as dioxin exceeds the standard. Dioxin, in particular, is the main cause of the "NIMBY effect" in MSWI power plant. Generally, domestic MSWI power plants often adjust relevant operating parameters based on the cognition and experience of operating experts on the MSWI process, but t...
