Abstract:
Experimental data on the effect of heat treatment (torrefaction) on thermotechnical properties of chicken litter pellets are presented. Initial raw material was heated in a nitrogen atmosphere with the rate of 10оС/min up to the torrefaction temperature Tt and then was held at this temperature during some time. Process of heat treatment lasted 60 minutes. Experiments were carried out at three temperatures Tt = 230, 250 и 270оС. To investigate the properties of the initial and torrefied materials the thermogravimetric analysis and differential scanning calorimetry were used. As a result, the data on the influence of torrefaction on devolatilization, ash content and combustion value of the granulated chicken litter were obtained. In addition hygroscopic properties of initial and torrefied material was measured. Listed thermotechnical characteristics were compared with similar characteristics of granular fuel made of wood. As a result of executed investigations it was shown that the torrefied granulated chicken litter can be used as a solid fuel for autonomous heating systems.
