Abstract
In this work, the bamboo ash fusion and sintering characteristics were studied to evaluate its potential application in combustion for the production of heat and power. Poplar and wheat straw were used in the experimental test as the reference fuels for comparison. Standard ash fusion tests and ash sintering tests were carried out at elevated temperatures. The results indicate that bamboo has a low ash melting temperature of 862 °C, much lower than that of poplar. In spite of the high K content in bamboo ash, no severe melting and sintering was observed under the temperature lower than 1000 °C. The ashes after the tests were analyzed using SEM/EDX, XRF, and XRD techniques to illustrate the ash transformation behavior. Standard ash fusion tests indicated that the melting temperatures of bamboo, wheat straw, and poplar ashes are 862 °C, 770 °C, and 1088 °C, respectively. No severe sintering can be observed for poplar due to the large existence of refractory compounds. Ash sintering occurred when the tempera...

Abstract Biomass fuels differ in many ways from the conventional fossil fuels used in combustion processes, such as coal. They often have high moisture contents, lower heating values, and a variety of minor constituents, such as chlorine, sulfur, phosphorus, nitrogen, and a variety of ash-forming metals. These special properties of biomass fuels cause several challenges, but in many cases also provide advantages, to their use in combustion processes. Design of the combustion devices and choice o...

Solid biomass ash related issues and adequate fuel characterization, especially for fuels with similar thermochemical properties, are still major challenges in combustion. As a consequence, the fuel switching and the valorization of unconventional available fuels are hazardous. An integrated strategy to characterize biomass fuels for ash related issues is applied to four residual woody fuels, namely, a mesquite wood mixture, rubberwood, an invader bush wood, and bamboo wood. The characterization...

Abstract This study focuses on the impacts of minerals naturally existed in different carbonaceous materials on the thermal processing of their blends with bamboo. Combustion characteristics, such as ignition temperature, peak temperature and burnout temperature, were studied using Thermogravimetric Analysis (TGA) to understand how thermal processing was affected by blending with different types of carbonaceous materials. Kinetic parameters, i.e., activation energy and pre-exponential factors, w...

To investigate co-combustion behavior of bamboo/coal blends, thermogravimetric analysis (TGA) was used to determine combustion characteristics of bamboo, torrefied bamboo, coal and their respective blends with five mixing ratios and three air flows. The results indicated that torrefaction was an effective way to improve physical properties of bamboo materials. The combustion process of bamboo and torrefied bamboo included drying, oxidative pyrolysis and char combustion. Torrefied bamboo had a lo...

Abstract Bamboo is one of the mostly fast growing natural resources and has great potential to be used as a valuable feedstock for biorefinery. The hemicelluloses, next to cellulose, represent a diverse group of polysaccharides in plant cell wall. Elucidation and understanding of the hemicelluloses from bamboo play an important role in the efficient conversion of bamboo into biofuels and bioproducts. This review summarized the recent reports on hemicelluloses from bamboo, including immunohistoch...

Abstract Bamboo is perennial woody grass, which distributed widely in the world and belonged to the Gramineae family and Bambuseae subfamily. It may be consider as a candidate lignocellulosic substrate for bio-ethanol production for its environmental benefits and higher annual biomass yield. The conversion of bamboo into bio-ethanol, bio-methane, natural food, flavonoids, and functional xylo-oligosaccharides production were reviewed in this paper. Future prospects for research include pretreatme...

Abstract The thermal behaviour and chemical characteristics of the bamboo species, Bambusa multiplex (BM), sourced from South Africa were investigated using thermogravimetric analysis (TGA). Torrefaction and low-temperature carbonization conditions were applied to samples of this plant at temperatures between 250 °C and 380 °C. The burning profiles for the raw and thermally treated bamboo samples co-fired with coal A at different ratios of coal inclusion were examined. The raw BM was found as th...

Abstract null null Biomass can be torrefied to improve the fuel quality prior to its utilization. In addition, a large number of soluble alkali metals can be removed by water washing, to solve slagging and other ash-related problems. In this study, computer-controlled scanning electron microscopy (CCSEM) was used to analyze the mineral composition and elemental distribution of straw, torrefied straw char, and torrefied-water washed straw char. The mineral transformation behavior and the distribu...

Abstract null null Combustion of agricultural residues for heat and electricity production is an efficient way to reduce amount of such waste source and emissions due to inappropriate treatment of them. However, unlike other biomass materials, agricultural residues often have high content of ash and certain ash forming elements with low meting temperatures, resulting in sintering and slagging during combustion processes. It complicates combustion of agricultural residues and restricts further ut...

Atlantic areas of southern Europe have low water restrictions but are also characterized by acid soils with low intrinsic fertility, so the selection of clones that have adapted to these characteristics is essential. In this study, biomass yield data for eight poplar clones established in two trials were evaluated after the first rotation. Both sites were representative of acid soils that had previously been used for agriculture and had low levels of alkali and alkaline earth elements. The first...

Combustion characteristics were determined using thermogravimetric and cone calorimeter. The results showed that pyrolysis temperatures significantly influenced the combustion features of bamboo charcoal. The increase of pyrolysis temperatures decreased the absolute content percentage of carbon, sulfur, oxyge...

Abstract The ash fusion behaviors of corn stalk (CS) and its variation mechanisms by two sludges [municipal-water sewage sludge (MW) and textile dyeing sludge (TD)] additions in an oxidizing atmosphere were investigated. Increasing the MW mass ratio led to an initial slow rise in the ash fusion temperatures (AFTs), but then they slowly decreased. The four characteristic temperatures for CS-TD all gradually increased as the TD proportion rose. An increase in the MW percentage led to changes in th...

The use of natural resources as an energy source is a well-studied alternative to fossil fuels. Some studies present bamboo as promising biomass for energy generation, and its transformation into briquettes can be a way to take advantage of its production residues. This study’s objective was to determine the physical and chemical properties of two bamboo ages (two and seven years old) of Bambusa vulgaris species to evaluate biomass quality and its briquettes for energy generation. Regarding the ...
