The importance of extractives and storage for sawdust as raw material for wood pellet production was analyzed. Sawdust prepared from eastern white pine (Pinus strobus L.), white oak (Quercus alba L.) and yellow-poplar (Liriodendron tulipifera L.) together with two commercial raw materials were extracted with acetone or stored at 60°C for 21days. The effects of the treatments were measured on the pellet...
The sawdust tar was generated from air–steam gasification in the fluidized bed reactor at atmospheric pressure. The gasification temperature and mass ratio of steam to sawdust were used as adjustable variables with which the amount of sawdust tar formation and the corresponding tar properties. Gel permeation chromatography (GPC) coupled with diode array detector (DAD) was employed to analyze the tar...
This article describes an experimental study on ash deposition during the co-firing of bituminous coal with pine sawdust and olive stones in a laboratory furnace. The main objective of this study was to relate the ash deposit rates with the type of biomass burned and its thermal percentage in the blend. The thermal percentage of biomass in the blend was varied between 10% and 50% for both sawdust...
