“…The most accurate and well defined approach for the modelling of biomass pyrolysis is to adopt the distributed activation energy model (DAEM) (Burnham et al, 1995;Burnham and Braun, 1999;Ferdous et al, 2002;Galgano and Blasi, 2003). The distributed activation energy model also applies to the pyrolysis of other materials, including fossil fuel, residual oils, resin chars (Zhu et al, 2009), medical waste (Koreòová et al, 2006), waste car tires (Folgueras et al, 2003), sewage sludge (Lakshmanan et al, 1991) and kerogen (Brown, 1988). DAEM has proven to be very successful in describing pyrolysis of various types of biomass under varying temperature ranges.…”

The paper focuses on the influences of some factors significant to pyrolysis of forestry biomass on the asymptotic solution of the non-isothermal n th -order distribution energy model (DAEM) using Gaussian distribution. Investigated parameters are the integral upper limit, the frequency factor, and the heating rate parameters of the Gaussian distribution. The influence of these factors has been used for evaluating the kinetic parameters of the non-isothermal n th -order Gaussian distribution from thermogravimetric analysis of forest waste.

“…One key feature of the TGA is its ability to determine the solid state reactions in a combustion process for which the mathematical descriptions are commonly defined in terms of their kinetic parameters, activation energy, E, and the Arrhenius parameter, A. An algebraic expression of the kinetic model for the solid state reactions related to the experimental data were previously proposed by many resources [3], [4], [9], [10], [13], as a function of the fractional conversion α, whereby f (α) can be written as:…”

Abstract. Dewatered sewage sludge is one of the largest contributors of waste material in Malaysia and it indirectly elevates local environmental problems. Previous studies have indicated sewage sludge as a potential alternative fuel based on its higher heating values. To explore sewage sludge as an alternative solid fuel will not only address energy demand issues, it will also mitigate long term disposal problems related with the waste material. Further information on combustion characteristics of this material is required before any links to power generation applications can be established. In this work the combustion characteristics of Malaysian sewage sludge was studied by means of thermogravimetric analysis (TGA) under different heating rates (10, 20 30 and 40 K/min). Non-isothermal thermogravimetric data were used to assess the kinetics of the combustion of sewage sludge by the application of Ozawa-Flynn-Wall and Vyazovkin kinetic models. The average activation energies were found to be 82 and 79 kJ/ mol respectively. The average reaction order corresponding to sewage sludge combustion was 0.11.

“…Thermogravimetric analysis is one of the instrumental methods used to analyse sewage sludge (Folgueras et al, 2003;Nowicki et al, 2008;. In the present study thermogravimetry (TG) and differential thermal analysis (DTA) were carried out on the tested sample.…”

Waste disposal is imposed by the European Union under Treaty of Accession concerning waste management order. One of the waste disposal methods is thermal utilisation. The paper presents an investigation of sewage sludge briquettes used as a fuel in combustion process. The research study was carried out on samples taken from the Municipal Wastewater Treatment Plant in Bochnia. Briquettes with lime were formed. The analysis of the elementary chemical composition of municipal sewage sludge, the composition of the ash and thermogravimetric analysis were carried out. The results indicate that the prepared briquettes had sufficient fuel properties.
