Through the millennia wood stoves for cooking have been notoriously inefficient and slow. Electricity, gas or liquid fuels are preferred for cooking when they can be obtained. In the last few decades a number of improvements have been made in woodstoves, but still the improved wood stoves are difficult to control and manufacture and are often not accepted by the cook. Gasification of wood (or o...

Increasing global concern over the environmental issues and depletion of fossil fuels, significant interest has been shown by the researchers to develop alternate energy technologies like biomass, biogas, solar to meet the future energy demand. The prediction of the performance of different biomass energy sources in gasifiers is needed for the implementation of this technology to fulfil the nee...

Thermal gasification of densified sludge/wastepaper fuels has been shown to be technically feasible for the co-disposal of sludge and source­ separated wastepaper. The performance and economic feasibility of a downdraft packed-bed gasifier system fueled with densified sludge/wastepaper and W的tepaper fuels has been evaluated. To assess the performance of the gasifier, a series of gasifier runs w...

The correlation between thermochemical provenance and biochar functionality is poorly understood. To this end, operational reactor temperatures (spanning the reduction zone), pressure and product gas composition measurements were obtained from a downdraft gasifier and compared against elemental composition, surface morphology and polyaromatic hydrocarbon content (PAH) of the char produced. Pine...

This work presents the modeling and thermodynamic analysis of two novel small-scale polygeneration systems that are capable simultaneously converting residual biomass to methanol (MeOH), electricity, heat a CO2-rich stream for agricultural greenhouses. The first system is based on downdraft gasifier, while second relies dual fluidized bed (DFB) gasifier. Both configurations leverage H2, O2, ele...
