Design of Domestic Pellet Burners: A Comprehensive Review

The rising demand for sustainable and energy-efficient heating solutions has propelled significant advancements in domestic pellet burner technology.Utilizing biomass pellets as a renewable energy source, these systems offer high thermal efficiency, reduced emissions, and cost-effectiveness, positioning them as viable alternatives to traditional biomass stoves.This review comprehensively explores recent developments in pellet burner design, combustion technology, material selection, control systems, environmental impact, and economic viability.Key findings reveal that forced-draft pellet burners outperform natural-draft models by achieving up to 25% higher efficiency through optimized airflow control [3,7].Additionally, circular burner designs demonstrate enhanced combustion stability and lower emissions compared to rectangular counterparts [7,13].Despite notable progress, challenges such as fuel variability, emission control, and cost barriers persist, necessitating further research.The future of pellet burner technology lies in optimizing combustion processes, standardizing fuel quality, and enhancing thermal performance to ensure consistent efficiency and broader adoption [20].
