Abstract

Cyclone Suspension preheater is an important part of the kiln unit which aims to separate materials and hot gases. The Suspension preheater consists of two strings, namely strings A and B and consists of 4 stages with stage 4 and stage 3 of string B not having a center tube. The efficiency calculation is carried out to determine the ability of the cyclone to separate material and gas and compare the efficiency of the cyclone which has a center tube with a cyclone without a center tube. The efficiency calculation is calculated using the Bohnet calculation. The efficiency calculation was obtained at stage 1 string A of 92.15%, stage 1 string B of 92.16%, stage 2 string A of 87.71%, stage 2 string B of 87.627%, stage 3 string A of 81.987%, stage 3 string B of 78.008%, stage 4 string A of 72.877%, and stage 4 string B of 73.459%. There was a decrease of 4% from stage 3 string A to stage 3 string B. A reduction in efficiency was observed in cyclones without a center tube. The gas flow in the cyclone is more regular with the presence of a center tube and has a longer residency time compared to a cyclone without a center tube. Acyclone without a center tube has a chaotic flow and turbulence can increase so that the separation between particles and gas is inefficient. The presence of a center tube effectively improves both separation efficiency and gas flow stability in the cyclone.
