Description

This dataset supports the research on the development and validation of a one-dimensional mathematical model of municipal solid waste (MSW) combustion in a moving grate furnace under air-fired and oxy-fuel conditions. The primary objective of the study was to investigate how oxidant composition, flue gas recirculation (FGR) ratio, oxygen distribution, and oxidizer temperature influence combustion performance, temperature distribution, fuel burnout, oxygen demand, and radiative heat transfer within the furnace.

The dataset includes:

(i) input parameters for the full-scale waste-to-energy (WtE) plant model (geometrical and operational data),

(ii) proximate and ultimate analyses of the modeled waste fuel,

(iii) thermophysical properties used in mass and energy balances,

(iv) kinetic parameters for devolatilization and char oxidation determined experimentally using thermogravimetric analysis (TGA) and isoconversional methods (Friedman and Vyazovkin), and

(v) numerical simulation outputs generated in MATLAB (temperature profiles, species concentrations, mass flow evolution, oxygen demand, and radiative heat flux).

The research aims to provide a design-oriented modeling tool for oxy-fuel waste incineration systems integrated with carbon capture technologies (BioCCS/BECCS), enabling assessment of process intensification, combustion chamber size reduction, and optimization of oxygen consumption.
