“…Regarding the gas products, Huchon et al [49] showed that an increase in feedstock moisture content from 11 to 23 % in a xed bed gasi cation reactor decreases the overall e ciency of the system and reduced the lower heaving value (LHV) of the product gas. This was caused by a decrease in CO and CH 4 and an increase in CO 2 in the product gas.…”

“…While there is no water present as the material is dried at this temperature, H 2 O is formed during the oxidation of the material ). This oxidation takes place at higher temperatures, in the smouldering front, which is situated below the WGS zone; and therefore this might be responsible for the slight increase in the WGS reaction and H 2 concentration [49].…”

Smouldering combustion has shown to be an effective application for soil remediation and as a waste treatment method for solids with high moisture content. The experimental set-up of smouldering combustion reactors is similar to autothermal fixed-bed gasification, updraft reactor configuration. In this study, smouldering experiments were conducted using lignocellulosic agricultural waste. The moisture content of lignocellulosic biomass was varied between 10 % to 50 %. Air flux was varied between 1.8 and 7.4 cm/s. Experiments were also conducted with varying oxygen concentration in the airflow (3.6 – 21 %), addition of sand (4 and 8 g/g) and other lignocellulosic material (wood pellets, and residual berry plant). Fuel gas with maximum H2, CO, CH4, CO2 concentrations of 7.7, 32.6, 2.3, and 57.4 % (N2 free) respectively were obtained with 10 % moisture content and 7.4 cm/s air flux. The smouldering yielded 1.24 Nm3/kgfeed_dry of gas with calorific value of 1.82 MJ/Nm3 (HHV).

“…For the needs of particleboard factories, combustion in boilers, gasification, and pyrolysis processes, the moisture content of woodchips is very important to be considered [17,18]. Dry biomass provides considerable benefits for combustion [19], such as increased boiler efficiency, lower flue gas emissions, and improved boiler operations, compared to fuels with high moisture [20,21]. Several attempts and methods have been carried out to reduce the MC of woodchips.…”

This paper is to study the drying method to reduce the moisture content (MC) of the woodchip. The methods used are to utilize the heat from solar and waste heat from the Biomass Power Plant (BioPP). By using a 250 °C heat waste from the BioPP, and stirring on the woodchip inside the drying equipment, the results obtained to reduce the MC from more than 40 % to MC around 20 % will take 2 h and 4 h faster than that which was not done on woodchips. Reducing MC from 40 % to 20 % will save 25.44 % on the woodchip consumption for combustion in the boiler of the BioPP. An analysis related to MC, CV, and woodchip consumption in generating electricity is also carried out. When MC is 26.70 %, the CV is 13.5 GJ T-1, and the woodchip consumption becomes 4.62 T h-1 and 1.31 T MWh-1, the energy produced is 764.7 kWh T-1. When the MC is higher, 47.68 %, causing the CV to become 9.8 GJ T-1, it is found that the consumption of the woodchips becomes 6.41 T h-1 and 1.81 T MWh-1, the energy produced is 551.3 kWh T-1.

“…Also, the combination of the last two can be implemented in a test bench. Taking into account that the power factor is a direct measure of the fuel conversion efficiency, it should be noted that the reactive loads lead to a decrease in the power factor [9]- [11].…”

Implementation of a 3.5 kW resistive load bank for a single-cylinder diesel engine test bench

This article presents the implementation of a 3.5 kW resistive load bank applied to a four-stroke single-cylinder diesel engine test bench that operates with an alternator. With this experimental test bench, it is possible to perform mechanical, thermodynamic, and polluting emissions studies in compression-ignited or induced internal combustion engines. Applying the quantitative research methodology, the design of the electric charging system is carried out. Power control circuits and safety elements are designed for the load back. CAD software is used to design the structure and casing considering anthropometric measurements. Also, finite element analysis (FEA) is incorporated to verify the structural and thermal design criteria. he implementation of an electrical and instrumentation acceleration system for sensing power and torque in low-displacement engines showed a measurement error of less than 1%. Similarly, the FEA allowed to quantify the maximum efforts and guarantee a safety factor above 5. With the characterization of the implemented sensors, a correlation coefficient of up to 99.97% was achieved. The power measurement displayed an error lower than 3%, which leads to a high characterization capacity of any thermal machine with equal power or less than the designed one.
