For gas-fired incinerators and biomass is the "integration" of the advantages of both direct biomass burning methods when excess air l > 1 with gasification means anaerobic, meaningful that excess air l < 1. In fact, when experimenting with this "sample", this furnace will cost a lot of money/cost and time. In order to minimize the cost of the experiment and shorten the experimental time, the experimental planning model used by the authors in this paper. The content of the paper refers to the study of the factors affecting the combustion and gasification process and the corn cobs based on the experimental planning model. The result of finding the maximum heat capacity value is 930.02 kWth and the temperature of the kiln achieved is 717.7°C corresponding to the moisture content of the fuel (corn cobs) is 24.89%; fan flow is 1127.3 m3/h; the amount of raw materials supplied is 199.96 kg/h.
