Optimization of Bottom Ash Water Slurry Flow Characteristics by using Commercial Additive
Authors: , , , , , ,
Abstract: In this study, the rheological feature of bottom ash-water slurry was investigated by using NaCl as an additive. The additive was added into the bottom ash suspension with proportions of 0.2, 0.4, and 0.6% (by weight). The range of solid concentration in the suspension varied from 10 to 60 % (by weight). When compared to the normal condition or without additive, the addition of NaCl results in a very obvious reduction in the apparent viscosity of the solution. The addition of 0.4% additive shows good agreement with the reduction of energy consumption as compared to the rest of the range of velocities. Because of the reduction in energy consumption, the required pump power decreased up to a remarkable limit of approximately 20%. Sensitivity analysis demonstrates that increasing NaCl concentration reduces apparent viscosity, pressure drop, and specific energy consumption, leading to improved flow efficiency. According to the findings of the investigation, the suspension of bottom ash slurry described in the above manner has the potential to be transported in a slurry pipeline using the least amount of energy.
