PENGARUH SUHU KARBONISASI DAN VARIASI KECEPATAN UDARA TERHADAP LAJU PEMBAKARAN BRIKET CAMPURAN SEKAM PADI DAN TONGKOL JAGUNG

Abstract

Biomass can be utilized as an alternative energy as fuel. Biomass contains the main elements of carbon atoms(C) derived from the content of cellulose, hemicellulose and lignin. Characteristics of briquettes can be seen from several things incluiding the carbonization temperature and air velocity affect the burning rate of briquettes, so the purpose of this research is to know the effect of carbonization temperature and air speed variation of the burning rate briquette mixture of rice husks and corn cobs. The research methodology includes material drying, carbonization at 200 ° C, 225 ° C, 250 ° C, 275 ° C, refining and filtering of 40 mesh materials, briquette printing and pressing with concentration of material mixing rice husks and corn cobs 50:50, and briquette drying. Further testing of flame briquettes with air veloci- ty 0,8 m/s, 1,1 m/s, 1,2 m/s, 1,3 m/s and 1,4 m/s. The results showed the briquettes are made by high carbonization temperature then the slower burning rate because of the low volatile matter with burning rate 0,46 gr/menit on carbonization temperature 225°C with air speed 1,4 m/s. The greater the air velocity, burning rate will be smaller because temperature heat will be wasted along with increasing air speed and optimum burning rate 0,42 gr/menit was found on speed 1,4 m/s with carbonization temperature briquettes 225°C
