- The research constitutes the form of an investigation to achieve the particular co-combustion characteristics of coal and rice husk by a fluidized bed combustor. An investigation was carried out using low rank coal of lignit type with particle size in the range of 1-2mm and rice husk by the size of 1-3mm. The fuel for combustion to be tested in the trial is provided at the combination of 10%, 20%, 30%, and 40% containing rice husk (dry basis). Experiments were conducted at fixed rates of 13.50 kg/hr. To obtain the combustion temperatures and gaseous pollutant emission a test was carried out by varying the excess air and the blending ratio of rice husk. The result of this study shows that the combustion temperatures and gaseous pollutant emissions such as CO, CO2, NO2, and SO2 were reduced substantially with the increase of the blending ratio of rice husk in coal. At blending of 40% rice husk in the coal fuel, the combustion temperature could reach up to 7850C at 40% excess air and produce the lowest temperature compared to the other. At 10% excess air, combustion of fuel with the content of rice husk of 10-40% results of CO emission reduced of 26%, CO2 of 35%, SO2 of 36%, and NO2 of 6%. Thus, a mixture of coal with rice husk can be used as fuel by burning simultaneously to the needs of environmentally friendly energy.
