Development of Biochar Stove from Agricultural Residue is a research project under the Research, Development and Engineering. The project was supported by. National Science and Technology Development Agency (NSTDA) Northern Region 2011. This research focuses on encouraging community Bring agricultural waste utilization. In the form of fuel The factors that directly impact on the economics, Biochar is the use of char in the form of solid fuel for cooking instead of fossil fuels such as gas, including reducing the use of firewood or charcoal, and is considered one of the major costs in the household is considered. that creates a sustainable development approach. As a result of lower costs and increase revenue by developing products that can be used in the form of reduced fuel costs, energy and bio-char can be sold to generate income for distribution back to the community.

            Production technology, Biochar stove in the study. As a guide in the development of renewable energy by means of chemical heat. So-called Pyrolysis. The nature of the stove can be used to produce bio-char, then. It can also use the stove, small household. This can be considered as non-complex technologies to the benefit to the actual user. For the attractiveness of Biochar design in this project. Is developing biologically active charcoal to cooking with charcoal producing Biochar. The nature of the stove are designed to form a cylinder, two layer in a place of burning. By entering fuel and heating the furnace normal stove.          The surrounding area is the area of ​​control of the reaction by Pyrolysis. Or thermal decomposition of biomass for heat transmission from the wall of the combustion zone.

            In addition, the area is still a shell casing is perforated ventilation holes. For the gas from the Pyrolysis process flow into the cavity of burning extra fuel during combustion. Thus, in a Biochar stove was designed so it is not necessary to enter the fuel. Reduce fuel consumption of the furnace, usually 40-50% and improves the thermal efficiency of the furnace is more than 30% of the active furnace to provide heat normally. Such stoves also provide products that can be utilized in the future, namely bio-char produced in the furnace shell. Including wood vinegar made from condensation. Products in the volatile by connecting pipe from the furnace shell to capture the substance itself.

The results of the research have knowledge and transmission of knowledge at Ban Nong-Ngeuak Community Pua District Nan and present the research in collaboration with a research group NSTDA* Northern Region. In Conference Research to solve local problems, the year 2015 which has been the focus group participants.
