Charcoals were produced from spruce and beech wood under laboratory conditions at different pyrolysis temperatures (300–1300 °C). Characterization of these charcoals was conducted using eight analytical methods. Each method describes specific changes in the temperature range until 1300 °C. Therefore, combination methods provides comprehensive information on stages. Fourier transform infrared (FTIR) spectroscopy, NMR thermogravimetry display 700 A prediction model for 800 °C is presented...
The influence of size and temperature on the heating auto-ignition beech (fagus sylvatica) spruce (picea abies) wood cubes were studied. Experiments conducted in a furnace at five isothermal temperatures (240 °C, 270 300 330 °C 360 °C) with four cube sizes (5 mm, 10 15 mm 20 mm). Temperatures inside recorded thermocouples (TC). Arising from experiments compared to mass-losses exothermic reactions measured simultaneous thermal analysis (STA). While up phases approx. can be seen curves due...
Abstract Opposed to piloted ignition, where a substance is ignited by an external flame or spark, the term auto-ignition describes onset of combustion spontaneous ignition without source. In this study, influence size spherical wood samples and temperature surrounding was investigated performing experiments in muffle furnace with beech spruce wood. On specially constructed rig, spheres four different diameters (8 mm, 12 18 25 mm) were put into preheated at five isothermal temperatures (240...
Abstract Oak heartwood usually darkens during and after drying. This darkening can be heterogeneous, leaving non-colored areas in the wood board. These light discolorations have been linked to heterogeneous distribution of tannins, but compelling evidence on microscale is lacking. In this study Raman fluorescence microscopy revealed precipitations crystalline ellagic acid, especially ray cells also lumina, cell corners walls (NCA), which had higher density. these denser free water longer...
