“…The concentrations of trace metal (loid)s in MSWI ashes were in the range of those in other MSWI ashes of different ages [ 12 , 18 , 20 , [51] , [52] , [53] ] but higher than e.g. in fresh MSWI ashes from India [ 54 ], Vietnam [ 55 ] and China [ 56 ]. However, a high variability of their concentrations in different incinerated bottom ashes ( Table S4 ) is evident because the resulting chemical composition of MSWI ashes is determined by the composition of incinerated waste, incineration technology and conditions, e.g.…”

“…The combustion of coal releases particulate matter, including y ash, that can affect the areas surrounding power plants. Furthermore, coal combustion cannot completely destroy inorganic materials such as heavy metals (HMs), which are present in y ash and are an environmental pollutant (Nguyen et al, 2022). The winter heating season has led to a ve-fold increase in PM 2.5 in the air (Xiao et al, 2015) and an increase in HMs attached to PM 2.5 (Deng et al, 2020) compared with normal levels in many parts of China.…”

“…[20,21] show that the fly ash (FA) produced via the MSWI process is toxic with a large yield. Fine PM, constituting the primary component of the FA produced via MSWI processing, is one of the leading sources of PM 2.5 in the atmosphere [22,23]. The composition structure of the incineration FA has obvious variability, with more irregular agglomerated structures, uneven PM surfaces, and dispersive PM distribution [24].…”

A 3D numerical model of the municipal solid waste incineration (MSWI) process was constructed based on a grate furnace with a daily processing capacity of 800 tons. Fluent was used for analyzing key factors affecting the concentration and diffusion level of particulate matter (PM). According to the actual MSWI plant working condition, a 3D model of the incinerator and the waste heat boiler has been constructed under benchmarks. Key factors affecting PM generation were determined by combining mechanistic knowledge and experts’ experience. They were the combustion temperature of solid phase municipal solid waste (MSW), the wall’s PM collision mode, and the second baffle length. Subsequently, the process of resolving the 3D numerical model was delineated. Then, a univariate analysis of the aforementioned 3D model was conducted for the three pivotal factors mentioned above. Conclusively, the effect of the important factors on the number of particles at the outflow of the incinerator was analyzed via orthogonal experiments to obtain the optimal combination. PM concentration initially diminished and then rose with the increased combustion temperature of the solid-phase MSW. Furthermore, a noteworthy reduction in PM concentration was observed when the second baffle length was 12.45–12.95 m. The greatest influence on the PM concentration of the outlet was posed by the wall’s PM collision mode, followed by the second baffle length. The appropriate adjustment of the combustion temperature of the solid-phase MSW, selection of wall materials, and design of the second baffle length were beneficial for diminishing PM concentration and ensuring long-term stable operation of the MSWI process. The combinative optimality of the three key factors was acquired via orthogonal experiments, which proved the subsequent optimal control of PM concentration at the outlet.
