“…By adopting waste heat recovery technology, factories can improve energy utilization efficiency and reduce environmental pollution [8]. For the waste heat recovery of stenter exhaust, various types of heat exchangers and heat recovery methods have been developed [9]. Some researches show that using waste heat of stenter exhaust to preheat air can save 10% and 13.6% energy comsumption [10][11].…”

In this study, combined with the exhaust adsorption, desorption and catalytic combustion technology, a waste heat recovery scheme using stenter exhaust to heat desorbed air and preheat stenter suction air was proposed. Using Aspen Plus to design the waste heat recovery system, and using Aspen EDR to design the structure of heat exchangers. The energy utilization efficiency of waste heat recovery system was evaluated through the exergy analysis, and the influence of exhaust flow rate variation on exergy efficiency of heat exchanger under different exhaust temperatures were discussed. Moreover, the influence of fluid parameter variations on the heat transfer process was also analyzed. Finally, the economic calculation was carried out and the overall energy-saving effect of waste heat recovery system was demonstrated. The results showed that the utilization of this waste heat recovery system can recover 537 kW, the exergy efficiency of desorbed air heat exchanger and preheating air heat exchanger were 51% and 58.9% respectively. In terms of the economic evaluation, the annual energy-saving economic benefits was about $ 89,312, and the static investment payback period was 1.17 years.

“…Baxi et al [13], using MATLAB SIMULINK software (https://www.tutorialspoint.com/matlab/matlab_ simulink.htm, accessed on 17 January 2024), developed a mathematical model for mass, moisture, and heat transfer balance for rotary dryers that can be used in different industries and demonstrated the applicability of the model in a stenter machine. Patel et al [14] conducted a comparison study based on energy modeling for two different stenter machines and belt conveyors. Based on their energy modeling, it was shown that cotton and wool fabrics could be dried and transported with ten percent less energy consumption when using stenter machines and belt conveyors.…”

Stenter machines are used to remove moisture from fabrics produced in the textile industry. Following the drying process, the cooling process, which is applied to fabrics using injector channels, is conducted in the last section of a stenter machine, preventing fabrics from expanding and the degradation of their quality. The present study mainly aimed to investigate the fabric-cooling process in a stenter machine used actively in a textile company. First, industrial data were obtained with some experiments, and computational fluid dynamics (CFD) simulations were then conducted by validating the industrial data. All CFD models were simulated using ANSYS Fluent commercial CFD software. A total of four parameters, including two geometric and two operating parameters, were considered in order to investigate their effects on the fabric-cooling performance of the stenter machine. While the geometric parameters were the porosity (β) and injector angle (α), the operating parameters were the velocity of the airflow that cools the fabrics and fabric velocity, representing the movement of the fabric. As outputs of CFD simulations, fabric surface temperature values, the distributions of fabric surface temperatures, and some streamlines were illustrated. Although low values of porosity (β1 = 0.05) and injector angle (α1 = 0°) provided better performance, airflow velocity could be increased one or two times for the range of these constant parameters.

Bu çalışmada, bir tekstil fabrikasında aktif olarak kullanılan bir ram makinesindeki hava akışı Hesaplamalı Akışkanlar Dinamiği (HAD) yöntemi ile modellenmiştir. Sayısal akış simülasyonları ANSYS Fluent paket programında gerçekleştirilmiştir. Akış rejimi daimi ve türbülanslı akıştır. Reynolds Ortalamalı Navier -Stokes (RANS) denklemleri Fluent'te çözdürülmüş, analizlerde Standart k-ε türbülans modeli seçilmiştir. Akış alanına ait hız verileri görsellerle sunulmuş ve akış verimliliğini etkileyen parametreler karşılaştırılmıştır. Analizler farklı düze geometrileri için gerçekleştirilmiştir. Geometri değişiklikleri düze açıklık oranı (B) ve düze açısı (α) değiştirilerek sağlanmıştır. Mevcut düze geometrisi ile farklı geometrilerin akış alanına ait hız değişkenleri üzerinden karşılaştırma yapılmıştır. Düze açıklık oranının %20-30 civarında ve düze açısının 0 o (ki bu düzenin yatay konumda olduğu anlamına gelir) olmasının ram makinesinde daha verimli bir akış sağladığı sonucuna varılmıştır.
