The biomass of fast-growing hybrid plants can be an effective source for energy conversion. The biomass of energy plants: hybrid poplar, hybrid willow etc., is a potential fuel for obtaining thermal and electrical energy. It should be noted that a small size downdraft gasifier, which is economically available and the most reliable equipment, is the most suitable for the use in small or medium production conditions for energy conversion of fast-growing willow biomass. The experimental confirmation of the mathematical model of fast-growing willow biomass gasification rate is proposed to carry out in the paper. According to the model, the rate of biomass gasification is proportional to the amount of biomass remaining ungasified. The gasification rate coefficients of four fractions of fast-growing willow biomass pieces and pellets were determined by the research results. During the research, the supply of oxidizer (air) to the working area (zone) of the downdraft gasifier was changed. When the air supply into a gasifier is minimal, the gasification rate coefficient is actually the same for all biomass fractions of fast-growing willow Salix Viminalis, L. and is 4.1·10-5 ± 0.1·10-5 s-1. With an increase in air supply the gasification rate coefficient increases and reaches its maximum value at an air supply of 9·10-3 m3·s-1, further increase in the air volume does not lead to an increase in the gasification rate coefficient. As the size of fuel pieces decreases, the rate coefficient also increases and is 9.476·10-5 s-1 for the fraction with the smallest pieces.

Real-Time PM2.5 Monitoring in a Diesel Generator Workshop Using Low-Cost Sensors

et al. 2022

Particulates from diesel generator operation are a known air pollutant with adverse health effects. In this study, we used low-cost particulate matter (PM) sensors to monitor PM2.5 in a diesel generator plant. We compared the measurement results from a PM sensor and a reference instrument (DustTrak), and we found a high correlation between them. The data overestimation or underestimation of PM sensors implied the need for data calibration. Hence, we proposed a data calibration algorithm based on a nonlinear support vector machines (SVM) model, and we investigated the effect of three calibration factors on the model: humidity, temperature, and total volatile organic compounds (TVOC). It was found that the TVOC correction coefficient has great influence on the model, which should be considered when calibrating the low-cost PM sensor in diesel generator operation sites. A monitoring network with six low-cost sensors was installed in the diesel generator plant to monitor PM2.5 concentration. It was found that normal diesel generator work, diesel generator set handling work, and human activity are the most dominant ways of producing particulate matter at the site, and dispersion is the main cause of increased PM2.5 concentrations in nonworking areas. In this study, PM2.5 emissions from two different diesel generators were tested, and PM2.5 concentrations at monitoring points reached 220 μg/m3 and 120 μg/m3, respectively. This further confirms that diesel generators produce many respirable particles when working.
