Experimental study on combustion characteristics of municipal solid waste

Area of Science:

• Environmental Engineering
• Chemical Engineering
• Energy Recovery

Background:

• Incineration is a widely adopted waste disposal method due to its safety, waste volume reduction, and energy recovery potential.
• Understanding the combustion characteristics of municipal solid waste (MSW) is crucial for optimizing incineration processes.
• Fluidized bed combustion offers efficient and controlled waste treatment.

Purpose of the Study:

• To experimentally investigate the combustion characteristics of municipal solid waste (MSW).
• To analyze the impact of key parameters on MSW combustion efficiency and emissions.
• To provide data for optimizing fluidized bed incineration of MSW.

Main Methods:

• Construction of a lab-scale fluidized bed combustion facility.
• Conducting multiple combustion runs with varying parameters: bed temperature (773-1143 K), fuel form (scrap/whole), and fuel moisture.
• Monitoring flue gas emissions (CO2, CO, SO2, O2, NOx) and in-reactor temperatures.

Main Results:

• Detailed experimental data on flue gas composition and temperature distribution were collected.
• Analysis of combustion behavior under different operational conditions was performed.
• The study provides empirical evidence on the influence of parameters like temperature and fuel type on MSW incineration.

Conclusions:

• The experimental investigation yielded valuable data on MSW combustion in a fluidized bed.
• Results contribute to a better understanding of emissions and thermal profiles during waste incineration.
• Findings can inform the design and operation of more efficient and environmentally sound waste-to-energy systems.
