TARIMSAL ATIKLARDAN ELDE EDİLEN KATI YAKITLAR

Doğrudan veya dolaylı olarak biokütleden elde edilen yakıtlara yeniden elde edilen katı yakıtlar denilmektedir. Bu çalışmanın ana amacı tarımsal atıklardan elde edilen briket haline getirilmiş seçilmiş bazı katı yakıtları incelemektir. Katı yakıtların kimyasal ve stokiyometrik kompozisyonları ile enerji dengeleri incelenmiştir. Isısal verim ve emisyon parametrelerinin belirlenmesinde ČSN EN 13229 (Katı yakıtlarla yakılan açık yanmaları da kapsayan ısısal donanımlar, araç ve gereçler – Gerekli şartlar ve test yöntemleri) teknik standartları esas alınmıştır. Denemelerde yoğuşmalı yanmalı bir soba prototipi (8 kW) SK-2 kullanılmıştır. Denemelerde kullanılan katı yakıtlar 65 mm çapında bio-briketlerdir. Bunlar; % 33 bozulmuş atık maya bulamacı ile % 67 odun talaşı karışımı, tahıl temizleme atıkları, 1:1 oranında karıştırılmış tahıl temizleme atıkları ile çayır ve 1:1 oranında karıştırılmış tahıl temizleme atıkları ve kanarya otundan oluşan mayalanmış karışımlardır

SOLID RECOVERED FUELS FROM AGRICULTURAL WASTES

Solid recovered fuels are fuels produced directly or indirectly from the biomass. Main goal of this work is to analyze some selected solid recovered fuels from agricultural wastes which were in form of briquettes. They were analyzed in order to find out chemical and stoichiometric composition and energy balance. Technical standard ČSN EN 13229 “Inset appliances for heating including open fires fired by solid fuels – Requirements and test methods” was performed to determine the basic assessment of thermal efficiency and emission parameters. A prototype of combustion accumulation stove SK-2 (nominal heat output of 8 kW) was used. Tested materials were the bio-briquettes with a diameter 65 mm from mixture of fermented mixture 33 % (rotten fermented waste treatment slurry) and 67 % wood ships, cereals cleaning residues, mixture of cereals cleaning residues and meadow grass in a ratio 1:1 and mixture of cereals cleaning residues and energy sorrel in a ratio 1:1.
