Fly Ash Particle Size Distribution from Coal and Biomass Co-firing Experiments

Laboratory and field test data on fly ash particle formation from co-firing biomass, inferior coal, and solid waste in a 330 MW utility boiler. The dataset includes results correlating coarse particle proportions with coal sulfur content, ignition temperature, and burnout rates, leading to optimization strategies that reduced particles larger than 45 μm from 52.2% to 36.0%. The research was authored by zixiu jia and last updated on 2026-05-10.

Use Cases

• Modeling the relationship between coal sulfur content and fly ash particle size based on described correlations.
• Optimizing combustion parameters like oxygen concentration and air flow to reduce coarse fly ash based on field test results.
• Analyzing the adhesion mechanism of molten (Fe-O-S) eutectics in particle agglomeration as described in the study.

Strengths

• Includes specific quantitative results, such as reducing particles >45 μm from 52.2% to 36.0% through optimization.
• Describes correlations between particle size and multiple fuel properties like sulfur content (1.04%) and ignition temperature (>680°C).
• Combines laboratory-scale investigations with field tests on a 330 MW unit, suggesting a practical validation component.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's 13.6 MB size suggests it is relatively small in scale.
