Biyoyakıt için mandalina budama atıklarının peletlenmesi

Amaç: Bu çalışmanın amacı, mandalina bahçesi budama artıklarının pelet şeklinde biyoyakıt potansiyelini değerlendirmektir. Yöntem ve Bulgular: Peletler, üç farklı parçacık boyutundan (4, 6 ve 8 mm) ve M10 (% 8 - 10) nem içeriğinde üretilmiştir. Peletlerin bazı ısısal ve fizikomekanik özellikleri güncel AB (Avrupa Birliği) standartlarına göre incelenmiş ve kontrol edilmiştir. Pelet yığın yoğunlukları 474 kg m-3 ile 507 kg m-3 arasında değişirken, pelet yoğunlukları 1230 kg m-3 ve 1270 kg m-3 arasında gerçekleşmiştir. Mekanik dayanıklılık (MD) değerleri %79.46 ile %92.14 arasında, sertlik değerleri 2039.34 N ile 2807.40 N arasında değişmiştir. Kül içeriği %5.64 ve peletlerin alt ısıl değeri 18.66 MJ kg-1 olarak tespit edilmiştir. Genel Yorum: Üretilen tüm peletlerin ölçülen fizikomekanik özellikleri katı biyoyakıt standartları açısından uygun bulunmuştur. Ayrıca, baca gazı emisyonları, çevre koruma için ısıtma yönetmeliklerinde belirtilen sınırlarlar arasında çıkmıştır. Peletlerin ısıl değerleri katı yakıt olarak kabul edilebilir düzeydedir. Çalışmanın Önemi ve Etkisi: Elde edilen sonuçlar, mandalina ağaçlarının budama artıklarının biyoyakıt kaynağı için hem teknik hem de çevresel açılardan uygunolduğunu göstermiştir.

Pelleting pruning residues of mandarin for bio-energy

Aims: This study evaluates the biofuel potential of mandarin orchardpruning residues in the form of pellets.Methods and Results: Pellets were produced at M10 (8 – 10%) moisturecontent, from three different particle sizes (ground by sieves having 4, 6and 8 mm). Some thermal and physical-mechanical properties of thepellets were studied and checked according to the recent EU (EuropeanUnion) standards. Pellet bulk densities varied between 474 kg m-3 and 507kg m-3, while the pellet densities varied between 1230 kg m-3 and 1270 kgm-3 Mechanical durability (MD) values varied from 79.46% to 92.14%.Firmness values changed from 2039.34 N to 2807.40 N. Ash content was5.64% and heating value of the pellets was 18.66 MJ kg-1.Conclusions: The measured physical-mechanical properties of theproduced pellets were in line with the related standards. In addition, fluegas emissions of all the produced pellets were in limits mentioned inheating regulations for the environmental protection aspects for bioenergy resource. Thermal values of pellets are very good as a solid biofuel.Significance and Impact of the Study: Results showed that the pruningresidues of mandarin pruning residues were suitable both in technical andenvironmental.
