Study and Evaluation for the Double-Chambered Incinerator Using Biomass Gas-Derived From Gasification

This research aims to study for the double-chambered incinerator using biomass producer gas derived from gasification process by adjust the optimal combustion characteristics that can efficiently prevent emissions from being released. 30 kilowatt-thermal of gasifier that can generate an average of 18 m 3 per hour of producer gas at the maximum fuel input rate of 15 kg per hour. The incinerator prototype consists of 2 combustion chambers with 2 gas burners installed, one for sample meat combustion and one for pollution elimination. The calculated proper volume of the primary chamber and secondary chamber were 0.10 m 3 and 0.03 m 3 , respectively, in order to maintain an adequate combustion residence time. The experiment shows the temperature of the primary and secondary rooms can achieve a maximum of 750 o C and 500 o C, respectively, when 100% of excess air condition was carried out. Meanwhile, a large input of excess air decreased the temperature inside the combustion chambers and also increased the flue gas opacity, which meant an increase of exhaust pollution in the atmosphere. In addition, an evaluated efficiency of the incinerator was 29-32 percent if only the primary chamber was operated. Accordingly, biomass producer gas is a feasible and appropriate renewable energy source to utilize as the main fuel for a double-chambered crematory in order to cremate the corpse and eliminate pollution simultaneously.
