The purpose of this study is to analyze fundamental combustion characteristics of woods used for indoor applications. The combustion characteristics such as heat release rate, total heat release, gas yield, and mass loss were analyzed by the method of cone calorimeter or thermogravimetry. These analysis results show that material properties of wood are closely related to flammability. It was shown that the relationship between the mass loss and gas emission. The results of combustion properties of woods would be useful for fundamentals of guiding the safe use of wood indoor application.

The aim of this study is to analyze the combustion and thermal properties in order to establish baseline data for the fire safety evaluation of domestic timbers. The combustion properties such as heat release rate, total heat release, gas yield, and mass loss were analyzed by the method of cone calorimeter test and thermogravimetry (TGA). Thermal decomposition temperatures of the specimens by TGA were recorded as 359.83°C for White pine, 359.80°C for Red-Leaved Hornbeam, 363.14°C for Carolina poplar, 358.59°C for Konara oak, and 362.11°C Sargent cherry. Red-Leaved Hornbeam showed the highest value of heat release rate, but, Carolina poplar wood showed the lowest value. In case of the total heat release, Red-Leaved Hornbeam wood showed the highest value and Carolina poplar wood showed the lowest one. The gas analysis results showed that Sargent cherry wood had the lowest value of 0.021, and Konara oak had the highest at 0.031 in the CO/CO2. The minimum value of mass reduction was recorded as 87.57% for Sargent cherry, but, on the other hand, it was 95.03% for Konara oak. There was a correlation between the gas generation of CO and CO2, and combustion behavior of woods. These results are expected to be usful for providing a fundamental guideline with the fire safety of wood use in interior applications.

The aim of this paper is to analyze combustion characteristics of treated woods by fire retardants which are prepared by several borate and phosphate compound solutions. The combustion characteristics for flame retardant treated wood were carried out using thermogravimetric analysis (TGA) to measure their combustion heat and flame retardant test using cone-calorimeter. The result of TGA and flame retardant test showed that single chemical solution affected the char forming and flame delay. The mixed retardants solutions was believed to be related to the efficacy and property of single chemical. The retention value and concentration of the retardants also affected the performance of fire retardant treated woods. The fire retardants FR1 and FR2 satisfied the requirement of The 3 Grade of Korean building codes.
