Abstract
The aim of this study was to produce a charcoal from bamboo and partial substitution for coal required in cement pyro processing to attain energy consumption. The effect of temperature and residence time on the yield of bamboo charcoal, mixing ratio of charcoal to binder ratio on the best binding mixture, and the ratio of mixing natural coal with bamboo charcoal to determine which percent of blending was promisingly substitute coal required in cement pyro processing was being investigated. Research sample collected from local and prepared. 60g of bamboo was be used as a basis for different trials with temperatures of, 350℃, 450℃ and retention time of, 10min, 15 min, and 20min. After six trials, we conclude that at a temperature of 450℃ and a retention time of 15min gives a yield of 32.5% that was be better compared, to the other trials. Then clay was be used as a binder and making briquette at different mixing ratio of charcoal to binder ratio (90:10, 80:20, 70:30) charcoal with better binder ratio and good combustion characteristics, was determined at 80:20, ratio. Finally we under take the proximate analysis by mixing natural coal with bamboo charcoal at different % ratio (90:10, 85:15, 80:20) here, concluded that 85% to 15% of natural coal to bamboo charcoal was promisingly substitute for coal required in cement pyro processing with fuel standard characterization limit . We have used design expert for data analysis. Generally, we were get high yield of charcoal briquettes by using clay as a binder at; temp 450ºC, retention time 15 min, charcoal to binder ratio 80:20 and 85:15 coal to bamboo charcoal that promisingly partial substitute for coal required in cement pyro processing to attain energy consumption with rate on return 48.7% and payback period of 1.84.
