“…The calorific value of the finer test sample was higher than that of the coarser SRF test sample. These discrepancies emphasize the heterogeneous nature of the SRF and how its characterization results can be affected by sampling and preparation methods [10]. 28.9 ± 0.1 NCV (as received)…”

“…Two main challenges have been identified in the REVaMP project for the use of a WDF in the aluminium scrap preheater combustor: (1) to condition the polymeric fraction from the automotive shredder residue (ASR) to prepare a suitable Solid Recovered Fuel (SRF) in accordance with the requirements of the standard EN ISO 21640:2021 for the specifications and classes of solid recovered fuels; and (2) to design a preheating system for the scrap metal based on the characteristics of the aforementioned recovered fuel and the heating requirements of the aluminium scrap. Although the SRFs obtained from ASR are fuels with an appreciable energy content (18-36 MJ/kg) [8][9][10][11], their incineration in an industrial plant may have several limitations, due to the ash produced and due to the potential emissions of heavy metals, furans, and dioxins [12,13]. Therefore, the operating combustion conditions and the flue gas cleaning systems will have to be specifically adapted to allow the incineration of SRF, as laid down by the Industrial Emissions Directive 2010/75/EU (IED).…”

“…Several authors have highlighted the convenience of conducting further investigations into SRF combustion reactions at a pilot and industrial scale [8,9,14]. It is necessary to go beyond the standard laboratory methods developed specifically for SRF properties and the commonly used thermo-gravimetric analyses [8,10,15,16] so that larger quantities of SRF can be investigated at the original grain size.…”

The use of alternative fuels derived from residues in energy-intensive industries that rely on fossil fuels can cause considerable energy cost savings, but also significant environmental benefits by conserving non-renewable resources and reducing waste disposal. However, the switching from conventional to alternative fuels is challenging for industries, which require a sound understanding of the properties and combustion characteristics of the alternative fuel, in order to adequately adapt their industrial processes and equipment for its utilization. In this work, a solid recovered fuel (SRF) obtained from the polymeric fraction of an automotive shredder residue is tested for use as an alternative fuel for scrap preheating in an aluminium refinery. The material and chemical composition of the SRF has been extensively characterized using proximate and ultimate analyses, calorific values and thermal degradation studies. Considering the calorific value and the chlorine and mercury contents measured, the SRF can be designated as class code NCV 1; Cl 2; Hg 2 (EN ISO 21640:2021). The combustion of the SRF was studied in a laboratory-scale pilot plant, where the effects of temperature, flow, and an oxidizer were determined. The ash remaining after combustion, the collected liquid, and the generated gas phase were analysed in each test. It was observed that increasing the residence time of the gas at a high temperature allowed for a better combustion of the SRF. The oxidizer type was important for increasing the total combustion of the vapour compounds generated during the oxidation of the SRF and for avoiding uncontrolled combustion.

“…The separate slopes of constant mass loss can be obtained from TGA [9,16,17]. Combustion reactivity studies by TGA can be found in the literature for both coal [18][19][20] and biomass fuels [21][22][23], but there exist a few comparison studies [24,25] and even fewer related studies about coal-biomass blends (CBBs) [26]. However, it is not enough to research biomass combustion properties only, because biomass itself cannot produce enough power in the current society.…”

This paper presents comparative research on the combustion of coal, wheat, corn straw (CS), beet residues after extracting sugar (BR), and their blends, coal–corn straw blends (CCSBs), coal–wheat blends (CWBs), and coal–beet residue blends (CBRBs), using thermogravimetric (TG) analysis under 10, 20, 30, 40 and 50 °C/min. The test results indicate that CS and wheat show better combustion properties than BR, which are recommended to be used in biomass combustion. Under the heating rate of 20 °C/min, the coal has the longest thermal reaction time when compared with 10 and 30 °C/min. Adding coal to the biomass can improve the burnout level of biomass materials (BM), reduce the burning speed, and make the reaction more thorough. The authors employed the Flynn–Wall–Ozawa (FWO) method and the Kissinger–Akahira–Sunose (KAS) method to calculate kinetics parameters. It was proven that overall, the FWO method is better than the KAS method for coal, BM, and coal–biomass blends (CBBs), as it provides higher correlations in this study. It is shown that adding coal to wheat and BR decreases the activation energy and makes conversion more stable under particular α. The authors selected a wider range of biomass raw materials, made more kinds of CBB, and conducted more studies on different heating rates. This research can provide useful insights into how to choose agricultural residuals and how to use them.

“…Combustion and oxy-combustion refers to an exothermic chemical process in which fuel reacts with air and oxygen, respectively. Burning of carbonaceous fuels usually takes place in the temperature range of 230–800 °C producing gaseous products mainly, CO 2 , CO, etc. − Assessment of combustion of rice, wheat, straw, char, coal, biomass fuels, and raw pet coke using thermogravimetric analysis (TGA) techniques is well reported in the literature. − A summary of work carried out by various researchers on the aforesaid systems is shown in Table .…”

Investigation on Kinetic Parameters of Combustion and Oxy-Combustion of Calcined Pet Coke Employing Thermogravimetric Analysis Coupled to Artificial Neural Network Modeling

et al. 2018

The objective of the present study is to understand the combustion behavior and to estimate kinetic parameters for combustion and oxy-combustion of calcined pet coke (CPC) employing thermogravimetric analysis (TGA), which is crucial for subsequent design and modeling of the combustion systems. In order to estimate the kinetics, the onset reaction temperature (ORT) is estimated using TGA for both the systems, and all subsequent experiments are conducted at temperatures higher than the ORT. The kinetic parameters viz., activation energy (E a ) and pre-exponential factor (A), are estimated using the shrinking particle model (SPM) and weight fraction model (WFM). While SPM assumes uniform particle size and first-order intrinsic kinetics, WFM is used to estimate even order of reaction besides E a and A. Prediction from SPM fits better to the data obtained from TGA, albeit with WFM estimating the order of the reaction as 0.6 in this case. The present study will be useful in employing the predicted kinetic data to design an industrial scale pet coke combustor. Artificial neural network (ANN) modeling is applied to isothermal TGA data to predict the TG curves of combustion and oxy-combustion of CPC. The ANN model predicted the TG curve with a high degree of accuracy, i.e., with a coefficient of determination in the order of 0.99999. The agreement between the experimental and predicted data substantiates the accuracy of the ANN model.
