As a major agricultural province in China, Northeast China produces a lot of biomass while its grain yield is high. Open burning is an efficient and convenient way to remove biomass. However, air pollutants (PM2.5, CO, VOCs) will be released in the process of biomass combustion, which will have a certain impact on Regional Environmental quality, atmospheric visibility and human health. Because of the various type of biomass, their combustion products and effects are different. In this study, there collected peanut hull, rice husk, straw and wood particles, and carried out the simulated combustion experiment in the laboratory environment simulation chamber. The inorganic elements, water-soluble ions and speciation analysis of combustion products were determined. The results showed that the content of Zn was higher than that of carcinogenic element in the eight inorganic elements after combustion. The water-soluble ion emission factors of wheat straw and wood particles are larger than those of peanut hull and rice husk, and the water-soluble ions are mainly K+ and CL. Through the morphology analysis of combustion products, it can be seen that different types of biomass have different morphology after combustion, which are mainly strip, column and particle. Combined with energy spectrum analysis, it is found that the content of K and CL is high. The results lay a theoretical foundation for the study of local biomass combustion and provide data for the determination of local biomass combustion emission characteristics.
