A Research on the Determination of the Gasification Performance of Grass Pellets
Öz: The gasification is the process of converting fuels which mainly contain hydrocarbon such as coal, petroleum, biomass, and solid wastes, into syngas which have combustible gases mixture such as CO, H2, CO2, and CH4 by partial oxidation. In this research, grass pellets were gasified in two different equivalent air coefficients of ER= 0.26 and ER=0.39, and gasification performances of pellets were determined. Gasification was carried out in a micro-scale gasification system in the gasification laboratory of the biosystem engineering department. Performance values as a result of gasification obtained at ER = 0.29 and ER = 0.36 equivalent air ratios are as follows: Biomass fuel consumption rates (FCR) were 8.6 kg/h and 6.5 kg/h. The lower heating values of the syngaswere 3831.7 kJ/Nm3and 3925.5 kJ/Nm3.The gas output rates (GFR) were calculated as 10.01 Nm3/h and 9.23 Nm3/ h. The amounts of syngas produced per unit biomass (GMb) were 1.57 Nm3/kg and 1.96 Nm3/kg. The thermal efficiencies of gasification process were 39% and 50%. During the gasification process, the temperature at the core zone varied between 700-800 oC. The performance values obtained as a result of gasification of grass pellet were compared with the performance values obtained from the previous studies on the gasification of biomass. It has been observed that the performance values obtained with 0.36 of equivalent air ratio (ER) are closer to the performance values obtained in previous studies.
Anahtar Kelime: Çim Peletlerinin Gazlaştırma Performansının Belirlenmesi Üzerine Bir Araştırma
Öz: Gazlaştırma, esas olarak kömür, petrol, biyokütle ve katı atıklar gibi hidrokarbon içeren yakıtların, kısmioksidasyon ile CO, H2, CO2 ve CH4 gibi yanıcı gaz karışımlarına sahip olan sentez gaza dönüştürülmesi işlemidir.Bu araştırmada çim peletleri ER=0.26 ve ER= 0.39 olmak üzere iki farklı hava fazlalık katsayısındagazlaştırılmıştır ve gazlaştırma performansları belirlenmiştir. Gazlaştırma işlemleri biyosistem mühendisliğibölümüne ait gazlaştırma laboratuvarında bulunan mikro ölçekli gazlaştırma sisteminde gerçekleştirilmiştir.ER=0.29 ve ER=0.39 hava fazlalık katsayılarıyla gazlaştırma sonucunda elde edilen performans değerleriaşağıdaki gibidir: Biyokütle yakıt tüketim oranları (FCR) sırasıyla 8.6 kg/h ve 6.5 kg/h olarak bulunmuştur. Eldeedilen sentez gazların alt ısıl değerleri 3831.7 kJ/Nm3 ve 3925.5 kJ/Nm3 olmuştur. Gaz çıkış oranları (GFR) 10.01Nm3 /h ve 9.23 Nm3 /h olarak hesaplanmıştır. Birim biyokütle (GMb) başına üretilen sentez gaz miktarı 1.57 Nm3 /kgve 1.96 Nm3 /kg olmuştur. Gazlaştırma işleminin ısısal verimi % 39 ve % 50 olarak hesaplanmıştır. Gazlaştırma işlemi sırasında kor bölgesindeki sıcaklık 700-800 oC arasında değişmiştir. Çim peletinin gazlaştırılması sonucuelde edilen performans değerleri, biyokütlenin gazlaştırılması ile ilgili olarak daha önce yapılan araştırmalarda elde edilen performans değerleriyle karşılaştırılmıştır. ER =0.36 hava fazlalık katsayısında elde edilen performansdeğerlerinin önceki çalışmalarda elde edilen performans değerlerine daha yakın olduğu görülmüştür.
