The combustion system for mixture of bio-mass fuels was improved to be set air heater between the combustion furnace and the rotary dry kiln. Then, thermal energy for the boiler is gotten from combustion gas of higher temperature. Furthermore, the temperature at the entrance of the dry kiln become to lower, and production of tar in drying air is avoided. To calculate of energy balance of this system, velocities and temperature of air in ducts are measured at 6 positions and 16 points. Results for a Long-term (24 hours) testing is compared to results of short-term (6 hours) testing. About 40 % of input energy is able to get out from this combustion system to the external system as thermal energy.
