Abstract Proximate analyses and decomposition profiles of solid fuels commonly used in Kenya were studied to determine their relative suitability for use as a clean efficient source energy households. The moisture, volatile matter, ash, fixed carbon content firewood, charcoal, briquette samples investigated, well under various temperature regimes. Except the ash sample, which deviated slightly ...

In solid biofuel manufacture technological and material variables influence the densification process and thus also the final briquette quality. The impact of these technological variables, especially compression pressure and compression temperature, and also of the material parameters (particle size and moisture content) can generally be observed during biomass densification in the quality ind...

ECBM displacement experiments are a direct way to observe the gas displacement process and efficiency by inspecting the produced gas composition and flow rate. We conducted two sets of ECBM experiments by injecting N2 and CO2 through four large parallel specimens (300 × 50 × 50 mm coal briquette). N2 or CO2 is injected at pressures of 1.5, 1.8, and 2.2 MPa and various crustal stresses. The chan...

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during boro season of 2014 to evaluate the effect of deep placement of nitrogen (N) fertilizers on N use efficiency and yield of BRRI dhan29 under flooded condition. The soil was silt loam in texture having pH 6.27, organic matter content 1.95%, total N 0.136%, available P 3.16 ppm...

In this study, charcoal-based briquettes prepared using bio-tar as a binder are proposed substitute for conventional coal in rural China; furthermore, the fuel properties of blends charcoal, semi-coke, and co-densification pollutant emission characteristics investigated. The addition charcoal improved heating value combustion index; however, small amount did not have any significant effect on s...
