“…To achieve stable power output, fuel comprised of mixed biomass sources, such as wood and straw, wheat straw and pine, stem wood and softwood bark, cassava rhizome and eucalyptus bark, peanut and tamarind shells, has been introduced and utilized in many power plants [4−7]. This technique is intended to not only overcome the fuel supply problem, but also to minimize emissions and reduce slagging and fouling propensities [5,8,9].…”

Biomass plays an important role in mitigating greenhouse gas (GHG) emissions. However, the major problem in using biomass is that inconsistent amounts are available throughout the year. The use of mixed fuels is one way to solve this problem. Based on the lumped system analysis method, this experimental study investigated the effects of excess air and energy fraction on the heat transfer coe cients of co-ring eucalyptus bark (EB) and peanut shell (PNS) in a twin-cyclonic swirling uidizedbed combustor (TS-FBC). The blended fuel was red at a xed heat rate for various energy fractions of secondary fuel (EF 2 ) and excess air (EA). The radial and axial heat transfer coe cients were observed: the average heat transfer coe cient of each operating condition showed signi cant effects for EA, while the effect for EF 2 was not obvious. The heat transfer coe cient could be improved by up to 11% in the bed region and by as much as 22% in the freeboard area when EA was increased from 40-80%.

“…Sustainable agricultural biomass residues produced by the Thai agricultural sectors on a large scale can be treated as CO2-neutral with regard to their combustion, i.e., reducing the CO2 net emission from the domestic power generation. Another benefit of biomass utilization through combustion is a quite low emission of SO2, typically due to insignificant sulfur content in biomass (Ninduangdee, Arromdee, Se, & Kuprianov, 2020).…”

This study aimed to experimentally investigate the effects of dry flue gas on biomass torrefaction. In this work, an oil palm frond (OPF) was torrefied in a laboratory-scale horizontal torrefaction reactor at temperatures of 240, 260, and 280 °C, with a residence time of 20 and 40 min, using dry flue gas with variable compositions (N2/CO2/O2: 76/16/8, 80/14/6, and 74/12/4). In addition, the experiments of conventional torrefaction were conducted for comparison. The effects of operating parameters on mass yield, the proximate and ultimate analysis, and the heating value of the fuel were investigated. The proposed method improved the fuel property of OPF substantially. With dry flue gas, OPF had lower moisture and volatile, and higher fixed carbon. The heating value of the selected biomass increased from 14.6 MJ/kg to 25.8 MJ/kg. Therefore, torrefaction using dry flue gas exhibited a potential for practical use for the biomass fuel pre-treatment method. However, this method resulted in a decreased mass yield and, consequently, the energy yield of the sample compared to conventional torrefaction.

“…The rate of waste accumulation in many regions of the world significantly exceeds the technological and economic possibilities for waste processing. The scale and high risk of environmental pollution determine the need for the developing waste-to-energy technologies in different countries ( Ninduangdee et al, 2020 ; Xiang et al, 2020 ). The current directions of these technologies are co-incineration, pyrolysis and gasification of various waste ( Medina Jimenez et al, 2019 ; Zhao et al, 2015 ).…”

Multiple-criteria decision analysis to substantiate the prospects of industrial and solid municipal wastes as slurry fuel components

This article investigates the recovery of typical wastes (coal slime, sawdust, cardboard and tire pyrolysis residue) as part of high-moisture slurry fuels. Using a laboratory furnace, the ignition and combustion characteristics of fuels as well as NO x and SO x emissions were determined. Using multiple-criteria decision-making (MCDM) methods and experimental results, we access the performance of four different slurry fuels in comparison with bituminous coal. The novelty of the study is based on the following features: we consider a unique set of parameters of the fuels (economic, environmental, safety and energy indicators), as well as three countries for their potential use (the USA, India and Russia); three different methods for calculating the efficiency indicator of each fuel were used. Despite rather low energy performance, the summarizing efficiency indicator of waste-based slurries was 53–93% higher than that of coal. The use of cardboard in the composition of a fuel blend showed the best complex result (the increase in the efficiency indicator was 80–93% relative to coal). The least promising additive was the pyrolysis residue of automobile tires. Its addition resulted in a 10–15% decrease in overall efficiency relative to a slurry without additives. The research results are useful for optimizing the component composition of waste-based slurries, technical and economic development of projects for the incineration of various wastes in the form of high-moisture fuel slurries.
