| Description |
Beehive charcoal briquettes were produced from powdered charcoal in which soil was added as binder. It was found to be an eco-friendly, clean and economic alternative source of household fuel for the people of Eastern Himalayan Region. Experiments were conducted to determine natural drying behaviour, normalised burn rate, temperature profile and emission of CO, CO , UBHC (unburnt hydrocarbons) and NOx of beehive briquettes prepared from 60:40; 50:50 and 40:60 ratios of charcoal and soil. It was observed that under natural drying conditions (temperature, humidity) briquettes took 433 hr to reach equilibrium moisture content of 5.56–10.29 %. Page's model was found suitable to describe the drying characteristics of all three combinations. Normalised burn rate varied between 0.377–0.706 % of initial mass min-1. Total burning time of briquette ranged between 133–143 min. The peak temperature attained by briquettes ranged from 437 ºC to 572 ºC. All the briquette combinations were found suitable for cooking and space heating. Emission of CO, CO , UBHC, NO and NO ranged between 68.4–107.2, 922–1359, 20.9–50.8, 0.19–0.29 and 0.34–0.64 g kg-1, respectively which were less than firewood.
