Abstract
Biomass is the only carbon-neutral fuel, the development and utilization of biomass are crucial for achieving carbon neutrality. However, the combustion of biomass in boilers is often unstable due to the heterogeneity of biomass raw materials, leading to a decrease in combustion efficiency and an increase in pollutant emissions. Continuous online monitoring is essential for the safe, stable and efficient operation of boilers. Traditional measurement methods typically rely off-line analysis to study the kinetics of biomass oxidation and pyrolysis. These methods struggle to accurately capture transient parameters during combustion due to changes in reaction pathways and oxidant products. Optical diagnosis is a non-contact, instantaneous and efficient method that can achieve in-situ, online and rapid measurement of multiple parameters. This technology has been extensively applied by researchers in the field of biomass combustion diagnosis. The current status and applications of online measurement methods for biomass ignition/combustion behavior and soot generation are reviewed. The problems and development trends of existing optical diagnostic technologies for biomass combustion are also been proposed. The review suggests that the future development of more diverse and effective optical diagnostic techniques, as well as the combination of various diagnostic technologies, is beneficial for comprehensively analyzing the key issues in biomass combustion, so as to realize the efficient utilization of biomass.
期刊介绍:
Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials.
The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy.
Key areas covered by the journal:
• Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation.
• Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal.
• Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes
• Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation
• Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
