Co-combustion, co-densification, and pollutant emission characteristics of charcoal-based briquettes prepared using bio-tar as a binder

In this study, charcoal-based briquettes prepared using bio-tar as a binder are proposed substitute for conventional coal in rural China; furthermore, the fuel properties of blends charcoal, semi-coke, and co-densification pollutant emission characteristics investigated. The addition charcoal improved heating value combustion index; however, small amount did not have any significant effect on semi-coke blend. blending with mass ratio 1:1 increased integrated from 7.73 × 10?12 (only semi-coke) to 16.92 K?3min?2. Results experiments suggest that effectively physical stability briquette. By increasing 0 9 wt% at densification temperature 20 °C, strength compaction drop resistance by 8.6% 13.9%, respectively. Increasing 50 °C resulted negative effects mechanical strength. Pollutant emissions were observed during ignition, stable combustion, burnout phases stove. had distinct influences, total suspended particle VOC emissions, which could be weakened or eliminated adding 3 hydrated lime. Herein, applied chain technical summarized. study provides support industrial application China, replication potential elsewhere.
