Abstract

Bir kömürün kalitesini belirleyen en önemli içeriği kül ve kükürttür. Bu bileşenler genellikle kömür içerisinde, ince taneler halinde dissemine şekilde bulunmaktadır. Dolayısıyla kömürlerden kül ve kükürdün uzaklaştırılması oldukça zordur. Falcon konsantratör, özellikle ultra ince kömürlerin yüksek merkezkaç kuvvetleri ile zenginleştirildiği yeni teknolojilerden biridir. Bu çalışmada, Konya Ermenek linyitinin Falcon Konsantratörü ile zenginleştirilme olanakları incelenmiştir. 1,5 l/dk besleme hızı sabit tutularak, -75+38 µm tane boyutlu linyite, farklı katı oranları (%20, %30, %40 ve %50) ve farklı merkezkeç kuvvetlerinde (20G, 100G, 176G ve 300G) testler uygulanmıştır. En iyi sonuçlar, %40-50 katı oranı ve 100G’den büyük merkezkaç kuvvetlerde elde edilmiştir.

Removal of Ash and Sulfur from Ermenek Lignite with the Falcon Concentrator

Year 2021, Volume: 21 Issue: 4, 927 - 933, 31.08.2021

Abstract

Ash and sulfur are the most important ingredients that determine the quality of coal. These components are generally found in coal in a disseminated form as fine grains. Therefore, it is very difficult to remove ash and sulfur from coals. The Falcon concentrator is one of the new technologies in which ultra-fine coals are enriched with high centrifugal forces. In this study, enrichment possibilities of Konya Ermenek lignite with Falcon Concentrator were investigated. By keeping the velocity of 1.5 L/min constant, -75+38 µm particle size lignite have at different solid ratios (20%, 30%, 40%, and 50%) and at different centrifugal forces (20G, 100G, 176G, and 300G) tests have been applied. The best results were obtained with 40-50% solid rates and centrifugal forces greater than 100G.
