FABRICATION AND EVALUATION BIOMASS OVEN PERFORMANCE

Biomass oven, which worked with agriculture waste, was fabricated for drying. Hot air was pureed with chemical materials to not be effect dried products with emission. Four rates combustion (12.5, 25, 50 and 60%) from combustion chamber volume, the best combustion rate was 25% as the highest temperature in drying chamber in less time and less  CO2 concentration. After chosen the best combustion rate, biomass oven was worked with three air velocities (1.4 - 2 and 2.5 m/s) to choose the best velocity, which achieves the highest temperature and less relative humidity in drying chamber in less time. It was actuated with the best combustion rate and velocity, thereafter chemical materials were used in the filters to reduce carbon dioxide concentration in the drying chamber air and increase the temperature at an average of 4.5 Co is higher than the use without them in filters.
