Rice Husk Gasifier Stove-Energy for Thai Agriculturalist

Abstract

A prototype of an inverted downdraft rice husk gasifier strove are designed and invented. The agricultural wastes such as rice husk have been used as the energy source. The thermal efficiency and real usage test are investigated. The results show that the maximum fuel loading is about 1.659 kg and the thermal efficiency is about 10.36%. The maximum power output of the strove (about 1.28 kW) was obtained when the input power value of fuel is 12.50 kW feeding into the strove. The average value of the fuel startup time, operating time, flame temperature and fuel consumption rate (FCR) are 2.87 min, 27.59 min, 416 – 684 °C and 3.184 kg/hr, respectively. This type of gasifier strove can be generated heat for cooking in many kinds of menus for example Tom Yum Gai (chicken Tom Yum). This menu can be finished within 25 min. To boil 2.0 liters of water for making hot beverages such as hot-coffee or hot-milk can be achieved within 8 min.
