To provide a rice hull heater which has a structure for utilizing rice hull combustion energy, and in which fumatory combustion effect of rice hull is stable for a long time and minimum necessary heating can be achieved, and further to provide the rice hull heater capable being easily assembled, easily moved and installed at a place where the rice hull exists, and easily operated.

This rice hull heater is a simple device capable of suppressing use of fossil fuel and holding down expensive equipment investment by applying the rice hull as agricultural waste defecated in large amounts, as a raw material. By using the rice hull as the agricultural waste as the raw material of the fuel, regional circulation type resources can be utilized, which builds regional agriculture and develops regional industries.
