CO-COMBUSTION SLUDGE IPAL PLTU TANJUNG JATI B UNIT 1&2 DENGAN BATUBARA : TINJAUAN ENERGI TERMAL PEMBAKARAN DAN PENGARUH TERHADAP EMISI SOX DAN SLAGGING PADA BOILER

摘要: Abstract Electricity production process at TanjungJati B unit 1&2 Power Plant is also producing B3 waste (sludge) obtained from water treatment plant. E-Green principles can encourage company to reduce amount of generated. A co-combustion (re-combusting the sludge with coal in boiler) be applied waste. Previous study literature shows there no experiment related between and coal. Moreover, characteristic (proximate, ultimate, chemical composition temperature ash fusion) effective for combustion are unknown. The aims this research find characteristic, evaluate caloric value combustion, effect coal-sludge emission potential slagging formation. carried out by proximate analysis (moisture, ash, volatile matter, sulfur content), ultimate (C, H, S, N, O), ( SiO 2 , Al O 3 Fe CaO, MgO, K O, Na TiO P­ 5 ), fusion temperature.

Based on existing boiler requirement conditions, mixing (20:1) (15:1) applicable due have enough low index, not exceed limit emission.The optimum condition (15:1).
