Sustainable thermal insulating materials produced from cellulosic fibers provide a viable alternative to plastic insulation foams. Industrially available, abundant, and inexpensive mechanical pulp fiber and recycled textile fiber provide potential raw materials to produce thermal insulating materials. To improve the fire retardancy of low-density thermal insulating materials produced from recycled cotton denim and mechanical pulp fibers, bio-based fire retardants, such as sulfonated kraft lignin, kraft lignin, and nanoclays, were coated onto sustainable insulating material surfaces to enhance their fire retardancy. Microfibrillated cellulose was used as a bio-based binder in the coating formula to disperse and bond the fire-retardant particles to the underlying thermal insulating materials. The flammability of the coated thermal insulating materials was tested using a single-flame source test and cone calorimetry. The results showed that sulfonated kraft lignin-coated cellulosic thermal insulating materials had a better fire retardancy compared with that for kraft lignin with a coating weight of 0.8 kg/m2. Nanoclay-coated samples had the best fire retardancy and did not ignite under a heat flux of 25 kW/m2, as shown by cone calorimetry and single-flame source tests, respectively. These cost-efficient and bio-based fire retardants have broad applications for improving fire retardancy of sustainable thermal insulating materials.

In this study, insulation thickness has been optimized by using exergy method and life-cycle cost concept for the case of using different lignites and natural gas separately. As a result, combustion parameters such as excess air, stack gas temperature, and combustion chamber parameters are much more effective on optimum insulation thickness. But fuel types, depending on its carbon and moisture content, are designative parameters on optimum insulation. The optimum insulation values are varied between 0.291 m and 0.1352 depending on the fuel types, wall types, and combustion parameters.

ÖzBu çalışmada, Tunceli, Hakkâri ve Kars illeri için derece-gün (DG) yöntemi kullanılarak dış duvarlara uygulanacak optimum yalıtım kalınlığı araştırılmıştır. Faiz ve enflasyon oranları dikkate alınarak toplam maliyet ve yalıtım maliyeti hesaplanmış ve bu değerlerin optimum yalıtım kalınlığı ile değişimi incelenmiştir. Duvar kalınlığına, yalıtım malzemesinin ısıl iletim katsayısına, yakıt tipine ve derece-gün değerine göre maliyet eğrileri oluşturulmuş ve geri ödeme süreleri hesaplanmıştır. Isı kayıplarını en aza indirmek ve maliyeti en düşük düzeyde tutmak amacıyla, binalarda yapılacak yalıtımın enerji verimliliği, sağlık, güvenlik, konfor ve bütçe konusunda nasıl bir etkiye sahip olduğu araştırılmıştır. Neticede Tunceli için optimum yalıtım kalınlığı 7.9 cm hesaplanırken, Hakkâri ve Kars için 8.2 cm ve 10.4 cm olarak bulunmuştur.Anahtar Kelimeler: Optimizasyon, yakıt türü, yalıtım kalınlığı The Calculation of the Optimum Wall Thickness for Heat Isolation in TheProvinces of Tunceli, Hakkâri, and Kars Abstract Optimum insulation thickness to be applied on outer walls using degree-day (DD) methods for the cities of Tunceli, Hakkâri and Kars was researched in this study. Total cost and insulation cost were calculated taking interest and inflation rates into account and the change of these values depending on insulation thickness was examined. Cost curves were created according to wall thickness, thermal conduction coefficient of the insulation material, fuel type and degree-day value and payback periods were calculated. To minimize heat abductions and to keep the cost at the lowest level, the effect of insulation in the buildings on energy productivity, health, safety, comfort and budget. As a result, while the optimum insulation thickness for Tunceli was obtained to be 7.9 cm, the optimum insulation thickness for Hakkâri and Kars were obtained to be 8.2 and 10.4 cm.
