This study analyzes the fuel conditions and environmental effects of converting heating in rural villages that rely on fossil fuels into wood fuel. Inparticular, we tried to derive the most important considerations when using wooden chips as fuel in aging agricultural villages where various variablessuch as weather, facility characteristics, fuel quality, and maintenance capabilities work. Above all, an experiment was conducted by comparing it withoak trees to determine whether Italian poplar, a representative attribute water created to supply fuel wood in Korea, is suitable for heating fuel. Through experiments, 1) Even though the supply of poplar wood chips during 10 hours of operation was 60.74 kg less than that of hardwood chips,the production of hot water was 140 kWh higher. 2) The higher the ex haust gas temperature, the proportional (increase) ox ygen concentration andinversely (decrease) PM and CO emissions. 3) Poplar has twice as much ash content as hardwood and three times more fine dust has been detected,but it meets all the standards for wood quality at the Korea Forest Science Institute. 4) Under the condition that there is a difference in water content(7.7%), hardwood cost 1.13 times more wood chips per 1 MWh than poplar, and even if the water content is corrected equally, hardwood cost 1.05times more per 1 MWh than poplar. 5) In conclusion, it was proved that the fuel possibility, economic possibility, and environmental possibility ofpoplar wood chips are sufficient.
