The Effect of Biomass Physical Properties on Top-Lit Updraft Gasification of Woodchips
(2016-04-12)
The performance of a top-lit updraft gasifier affected by biomass (pine wood) particle size, moisture content and compactness was studied in terms of the biochar yield, biomass burning rate, syngas composition and tar ...
The Effect of Gasification Conditions on the Surface Properties of Biochar Produced in a Top-Lit Updraft Gasifier
(2020-01-19)
The effect of airflow rate, biomass moisture content, particle size, and compactness on the surface properties of biochar produced in a top-lit updraft gasifier was investigated. Pine woodchips were studied as the feedstock. ...
Airflow and insulation effects on simultaneous syngas and biochar production in a top-lit updraft biomass gasifier
(2017-10-11)
The objective of this study was to understand the effect of airflow and insulation on syngas and biochar generations of rice hulls and woodchips in a top-lit updraft gasifier. Biochar yield decreased with increasing airflow. ...

Remote sensing of temperature changes in Panama canal watershed from landsat
(2010-09)
La temperatura de superficie es un factor central, como variable de control en los estudios de cambio climático, balance de calor y modelos climáticos. El conocimiento de la temperatura de superficie es importante para ...
Influential factors affecting inherent deformation during plate forming by line hating (Report 1) - the effect of plate size and edge effect
(2007-09)
The authors aim to propose an accurate and practical method to predict the deformation of actual plates of large size such as those used in shipbuilding. This method is to be used to improve the accuracy of an automatic ...
Numerical study of inherent deformation produced in thick plates through bending by line heating
(2006-06)
In ship building, line-heating is widely employed as an effective method to form steel plate with complex 3-dimensional carved geometries. However the plate bending by line heating is strongly dependent on skills. To ...
