The aim this study was to adjust the general model for determining log steaming time, proposed by Steinhagen et al. (1980), for Eucalyptus grandis wood. In order to do so, logs with diameter from 20 to <25, 25 to <30 and 30 to <35 cm were collected from 14 trees of Eucalyptus grandis derived from the `Horto Florestal' nursery, Manduri, São Paulo. A thermocouple was inserted into each log near its center. The logs were steamed during 20 hours at 90ºC and 100% relative humidity. A data logger recorded the temperatures during the thermal treatment. It was concluded that the Steinhagen et al. (1980) model cannot be directly used for this species in study and corrections factors are proposed for the utilization of the general model for log steaming time, developed by Steinhagen et al. (1980), for Eucalyptus grandis wood.
