Combustion properties of Rowan wood impregnated with various chemical materials
The common use of Rowan wood (Sorbus aucuparia Lipsky) in the forest products industry of Turkey, was evaluated for some of the combustion properties after impregnation with various chemical materials. For this purpose, the wood test samples prepared from Rowan wood materials according to TS 345 were treated with Tanalith-E, Vacsol-Azure, Imersol-Aqua and Boron compounds (Borax and Boric asid) by the vacuum impregnation process in accordance with ASTM D-1413 standards and directives of the manufacturer. After impregnation, each sample was tested for observation of retention amount and combustion properties (ASTM E 160-50). It has been proven that combustion properties of the impregnated Rowan wood materials were affected by impregnated materials. As a result, combustion temperature was measured as highest in Imersol Aqua (458.686°C) and the lowest in Borax (439.023°C). The impact of impregnation material decreases after the ignition and the main impact was in flame sourced combustion. In addition, boric acid reduces the material loss in combustion, ensuring that the material is more resistant to sudden collapse and destruction. As a result, it appears that impregnation of wood material with appropriate boron treatment will further increase combustion temperatures and provide additional fire resistance and a degree of security.

Combustion properties of wood impregnated with commercial fertilizers
The objective of this study was to determine some combustion properties of Calabrian pine (Pinus brutia Ten.) wood specimens impregnated with aqueous solutions of commercial fertilizers. Ammonium sulphate (AS) and diammonium phosphate (DAP) were used as commercial fertilizers. Diammonium phosphate and ammonium sulphate fertilizers were impregnated into wood at 10, 20, and 30% concentrations prior to combustion test. Then, combustion test method containing flame source, without flame source and glowing stages was performed according to the ASTM E 160-50. Results indicate that fertilizer treatments improved the combustion properties of Calabrian pine specimens. In terms of mass loss, duration of without flame, and glowing stages as well as and the destruction time, Calabrian pine specimens impregnated with 30% DAP gave the best results. Higher concentration levels of fertilizers resulted in better combustion properties of wood.
