Abstract: Disclosed is a method for calculating combustion in the bed of a waste incinerator. The method is based on a model of combustion in a waste incinerator bed and comprises a water evaporation model, a volatile matter analysis model, a volatile matter combustion model, and a fixed carbon combustion model. The volatile matter of the volatile matter combustion model comprises CO, H2, CH4, NH3, and H2S. The volatile matter combustion model comprises a combustion reaction equation for said volatile matter and O2, and respective equations for CO and CH4 reacting with water vapor. Equations governing the model of combustion in the bed of a waste incinerator comprise a continuity equation, an energy equation, a momentum equation, and a component equation. Boundary conditions of said governing equations comprise: equations of heat transfer and mass transfer from an upper boundary layer of the bed to the exterior; and equations of heat transfer and mass transfer from lower boundary layer of the bed to the exterior.

Abstract: The present disclosure provides a copper-magnesium co-doped carbonized wood sponge material, a preparation therefor, and an application thereof, and a method for converting plastics into fuel based on a Fenton-like system. In the present disclosure, a copper-magnesium co-doped carbonized wood sponge catalyst is prepared by high-temperature pyrolysis after a wood raw material is coated with polydopamine (PDA) and a copper element and a magnesium element are loaded on a wood sponge substrate, realizing the loading of a nanoreactor on a wood sponge layered structure, and forming a unique spatial microenvironment and synergistic effect by combining a superior three-dimensional lamellar structure of the wood sponge substrate with the structural advantages of the nanoreactor to promote an electron transfer pathway on a surface.
