Abstract

In this study, experiments have been carried out to investigate the effect of temperature on final product yield of pyrolysis of municipal solid waste. In addition, rotary kiln is numerically modeled, mass, energy and momentum equations are derived. At the same time, a finite element model was constructed for a pyrolysis reactor designed at three different aspect ratios. A total of 81 computational fluids dynamics analyzes were carried out by using different values for inlet temperature, particle size and rotation speed with data from Kocaeli province environmental situation report' 2015. According to the analysis conditions, where the maximum methane gas yield is obtained, the energy potential that can be obtained from the municipal solid wastes was calculated. It has been observed that the experimental data overlaps with the analysis in terms of methane yield.

Hesaplamalı Akışkanlar Dinamiği Kullanılarak Kentsel Katı Atıkların Pirolizinin Deneysel ve Nümerik İncelenmesi

Abstract

Bu çalışmada, sıcaklığın kentsel katı atık pirolizinin nihai ürün verimi üzerindeki etkisini araştırmak için deneyler yapılmıştır. Ayrıca döner fırın sayısal olarak modellenmiş, kütle, enerji ve momentum denklemleri türetilmiştir. Aynı zamanda, üç farklı en-boy oranında tasarlanmış bir piroliz reaktörü için sonlu elemanlar modeli oluşturulmuştur. Kocaeli ili çevre durum raporu 2015'ten alınan verilerle giriş sıcaklığı, tane boyutu ve dönüş hızı için farklı değerler kullanılarak toplam 81 adet hesaplamalı akışkanlar dinamiği analizi gerçekleştirilmiştir. Maksimum metan gazı veriminin elde edildiği analiz şartlarına göre, kentsel katı atıklarından elde edilebilecek enerji potansiyeli hesaplanmıştır. Metan verimi açısından deneysel verilerin analiz ile örtüştüğü görülmüştür.
