The Effects of Wood Preservatives on the Combustion Characteristics of Sessile Oak (Quercus Petreae L.)

This study carried out to determine the combustion properties of the sessile oak wood (Quercus petraea L.) which impregnated with wood preservative and subjected to surface treatments. For this purpose, the samples, which were prepared from sessile oak wood according to ASTM–E 160-50 combustion principles,  impregnated with wolmanit-CB (WC) and tanalith-E (T) in accordance with ASTM-D 1413-76 and then synthetic (St) and Water-based (wb) varnishes were applied according to ASTM-D 3023. The combustion test was carried out in 3 stages, combustion with flame (CWF), self-combustion without flame source (CWOF) and ember combustion stage (ECP). It was aimed to determine the combustion temperature values in CWF, CWOF and ECP stage, weight loss, total combustion time and demolition time. As a result, impregnation applications have increased the total combustion time to between 15-18% and reduced the demolition period. The exact opposite results were obtained for the varnish types, the total combustion time was reduced by 19-21% and the demolition time increased by 10-22%. In CWF stage, the highest temperature was obtained in water-based varnished samples (490 °C), the lowest in non-varnished samples (458 °C); in CWOF stage the highest temperature in water-based varnished samples (572 °C), the lowest in synthetic varnished samples (544 °C); and in ECP stage the highest temperature in non-varnished samples (306.5 °C), the lowest in the samples with the synthetic varnished (262.7 °C).
