Abstract
In this study, experiments were carried out to evaluate the fire risk of a firewood boiler, which is mainly used as a winter heating apparatus in rural areas. The ambient temperatures of the combustion chamber and the duct were measured. The fire risk of tar inside the duct was also investigated. The temperature decreased less than $40^{\circ}C$ in the region more than 40 cm from the combustion chamber. Fire- flakes were scattered in the range of less than 60 cm from the combustion chamber. The temperature inside the rose to above $600^{\circ}C$. At 2 m from the boiler body, the temperature inside the duct was increased to about $420^{\circ}C$. The ignition temperature of tar was about $398^{\circ}C$. The temperatures of the boiler and duct surface were above $300^{\circ}C$. Combustible material ignited when it contacted the boiler surface or duct surface.
