The Design and Build Husk Furnance Heat Automatic Shut-Off

Abstract

This article aims to study and research the design of a high quality rice husk furnace built with a high temperature furnace and an automatic-lid. In order to improve the design and construction process of the furnace lid, the design concept was
based on lower costs, user-friendliness, movability and a solution to the time consumption in checking the combustion process of black rice husk ash. In the first experiment, 18 kilograms of raw rice husks were burned in the original furnace for 5 hours. The amount of black rice husk gathered from the burning was 7.5 kilograms or 41.67%. Then the process was redone using the re-designed rice husk furnace, which has an automatic-lid and was operated by a set of solar power generators. The temperature of the burning was set at 280°c. The experiment was tested by burning 18 kilograms raw rice husks until the heat reached the bottom of the tank at 280°c. The furnace was automatically shut off by a sensor. The collection of black rice husk was 8.3 kilograms or 46.12%. The results showed an increased number of black rice husk compared to the first method, with a decrease in the amount of time needed to check the burning process. In addition, the results found that the quality of the black rice husks greatly improved, which can be measured by the percentage of the ash. In general, the percentage of good quality black rice husks can be indicated by the amount of ash, which should not exceed more than 10%. Likewise, the results showed that there was only 5% of the ash from using the redesigned rice husk furnace.
