“…The temperature inside the boiler is higher than when using spent coffee grounds to heat water with a capacity of 40.1 kg, producing a maximum temperature of 78.5 °C (Kang et al 2017). Compared with wood pellets and domestic wood pellet boiler, where the water outlet temperature was 70 °C (Euh et al 2016) (Carlon et al 2016) and 79 °C (Kang et al 2013), respectively, a much higher water outlet temperature of 99 o C was obtained from using coconut shells. This experiment also shows that a high water flow rate reduces the temperature of the water outlet, which is caused by a reduction in the heat absorbed by the water.…”

Agricultural waste products, such as wood, rice husk, corn waste, and coconut shells, are abundantly available and can potentially be used as an energy source, particularly for direct combustion in boilers. Because coconut production increases every year, it would be useful to find an alternative use for coconut shells, which are a type of coconut waste. As coconut shells can be used as fuel in boilers, the aim of this study was to evaluate the thermal characteristics of coconut shells in this regard. This study used experimental results to evaluate the performance of a boiler when coconut shells were used as solid fuel. The variations in feed rate were 5, 7.5, and 10 kg/h, and the water flow rates varied between 1 litre per minute (lpm), 2 lpm, and 3 lpm. Temperature data were collected every second via data acquisition , and the mass flow rate of the flue gas was collected every 5 min using a pitot tube equation. One of the parameters evaluated in determining the success of coconut shells as boiler fuel is the thermal efficiency of the boiler. The results showed that the maximum thermal efficiency reached approximately 62.04%, and the maximum flue gas temperature was approximately 500 ℃ for a biomass mass flow rate of 7.5 kg/h. The maximum water temperature of the boiler was 99 ℃, which was reached at a minimum water flow rate of 1 lpm. The results showed that coconut shells are suitable for use as boiler fuel.

“…Biomass is one of the important renewable resources to be developed for energy utilization. The demand for biomass fuel is increasing due to its carbon-neutral and renewable properties [1,2] and the importance of the increased demand in the energy market [3]. Biomass is mainly composed of wood, short-rotation woody crops, agricultural residues, herbaceous species, municipal solid wastes, food processing wastes, aquatic plants, and animal wastes [4].…”

“…Biomass is mainly composed of wood, short-rotation woody crops, agricultural residues, herbaceous species, municipal solid wastes, food processing wastes, aquatic plants, and animal wastes [4]. Woody biomass is densified into pellets from sawdust and waste wood after the milling, drying, and compression processes [1,5]. The purpose is to improve the physical and mechanical properties of wood biomass by producing a homogeneous quality regarding the particle density, moisture content, and uniform shape and size.…”

“…The purpose is to improve the physical and mechanical properties of wood biomass by producing a homogeneous quality regarding the particle density, moisture content, and uniform shape and size. Wood pellets have some advantages, such as being suitable for transport and storage, and their high energy density, durability, and use in a heating system [1]. As an interesting biomass fuel, the demand for wood pellets is predicted to increase continuously and become mostly supplied both domestically and internationally, which will also be increased in the coming years, such as in the EU countries [6].…”

Studying the thermal decomposition of wood pellets is an important subject in order to understand the behavior of wood pellets during the combustion process. In fact, wood pellets have become an important fuel used in boiler combustion. The objective of this study is to investigate the mass loss and elemental analysis of pine wood pellets at various times and temperatures. Commercial pellets with a diameter of 6 mm were used. The experiment was conducted in the laboratory of the Engineering University of Minho. The pellets were burned in a small reactor of 1.36 kW with a maximum temperature range of 1150 °C. The data were observed at different temperatures: 264, 351, 444, 541, 650, and 734 °C, and at time intervals of 30, 60, 120, 180, 240, 300, 600, 900, 1200, and 3600 s. The results of the experiment revealed that the reaction rate increases with the temperature, and the higher the combustion temperature applied, the higher the mass loss of all substances observed. The remaining mass, as fixed carbon and ash or unburned substances, is about 3%. The residence time and temperature influence the species concentration of wood pellets.

“…The advantages of biomass, besides being a renewable and inexhaustible fuel source [1], is that it provides employment opportunities in rural areas [8]. Global utilization of biomass is increasing because being considered carbon neutral [9] can address the pressing need to reduce greenhouse gas emissions [10]. Biomass can be obtained from agricultural waste or fast-growing plants [11], industrial residues and process waste, sewage, and animal wastes [12].…”

This paper assesses the potential of biomass energy resources in Timor-Leste (TL). Although other renewable energy sources are mentioned in this article, such as wind energy, solar energy, hydropower, bioenergy, including bioethanol and biogas, the main goal is to gather the data on biomass in TL and provide such data as useful information for a wide range of end-users. The current evaluation is based on various sources which include previous assessments on biomass and other renewable sources. The energy potential of biomass in TL apart that resulting from vegetation or flora and animals is also derived from agricultural waste, such as waste from rice, corn, and coffee. The analyses also include the contribution of agricultural waste, animal waste, and that from urban waste. The results from this article show that the potential of usable biomass energy in TL from forestry and agriculture is 1.68 × 106 toe/year, animal waste is 4.81 × 103 toe/year, and urban solid waste amounts to 9.55 × 103 toe/year. In addition, it is concluded that biomass alone can fully replace fossil fuels for electricity generation.
