Article discusses effect of environmental condition on heat transfer from wood sample during burning process. The aim of the paper is to characterize temperature vs time dependence of irradiated wood surface as a function of heat source distance , total heat transfer coefficient and thermal diffusivity . From temperature vs time dependence on the irradiated side is possible to compute heat ignition temperature of wood as one of the most important characteristics of wood burning. All measured values of studied parameters are in very good agreement with table values.
