Pengaruh Penggunaan Broke System Terhadap Pemakaian Steam
The broke system is a system for reprocessing rejected or defective pulp stock that is collected in the broke tower tank. In the broke tower, stock from wet broke and dry broke (pulp rejects) is utilized to the maximum extent possible to minimize industrial waste, so that broke becomes an additional raw material in the production of pulp sheets in the pulp dryer. The objective of this final project is to study the effect of the use of broke on steam consumption in the dryer section, particularly analyzing the effect of using different broke ratios on steam consumption. In the Final Project, it was found that the broke system has an impact on steam consumption in the pulp dryer. Based on the analysis results, the higher the use of broke pulp ratio, the less steam is used. Increasing the broke ratio in the slush pulp mixture in the high-density tower tank results in minimal steam usage. At a broke ratio of 0–10%, there is a significant impact on steam consumption efficiency, but when exceeding 15–90%, steam usage decreases significantly. This is due to the extremely high use of the broke ratio. Optimizing the broke ratio above 15% can reduce steam usage and lower operational costs.
