This paper introduces an energy-saving biomass stove. The principle of energy-saving biomass stove is gasification. It is a chemical process, transforms solid fuel into a gas mixture, called (CO + H2 + CH4) gas. Emission lines in the stove chimneys typically remain high temperatures around 90° to 120°C. The composition of the flue gas consists of combustion products of rice husk which are mainly CO2, CO, N2. A little volatile in the rice husk, which could not burn completely, residual oxygen and dust will fly in airflow. The amount of dust in the outlet gas is a combination of un-burnt amount of impurity and firewood, usually occupied impurity rate of 1 % by weight of dry husk. Outlet dust of rice husk furnace has a normal size from 500μm to 0.1 micron and a particle concentration ranges from 200-500 mg/m3. Gas emissions is created when using energy-saving stove and they will be used as the main raw material in combustion process Therefore the CO2 emission into the environment when using the stove will be reduced up to 95% of a commonly used stove. Bài báo giới thiệu một bếp tiết kiệm dùng năng lượng sinh khối. Bếp tiết kiệm năng lượng thực hiện nguyên lý khí hóa sinh khối. Đó là một quá trình hóa học, chuyển hóa các loại nhiên liệu dạng rắn thành một dạng hỗn hợp khí đốt, gọi là khí Gas (CO + H2 + CH4). Dòng khí thải ra ở ống khói của bếp thông thường có nhiệt độ vẫn còn cao khoảng 90° ~ 120°C. Thành phần của khói thải bao gồm các sản phẩm cháy của trấu, chủ yếu là các khí CO2, CO, N2, một ít các chất bốc trong trấu không kịp cháy hết, oxy dư và tro bụi bay theo dòng khí. Lượng bụi tro có trong khói thải chính là một phần của lượng không cháy hết và lượng tạp chất không cháy có trong củi, lượng tạp chất này thường chiếm tỷ lệ 1% trọng lượng trấu khô. Bụi trong khói thải lò đốt trấu thông thường có kích thước hạt từ 500μm tới 0,1μm, nồng độ dao động trong khoảng từ 200-500 mg/m3. Lượng khí thải được sinh ra khi sử dụng bếp tiết kiệm năng lượng, sẽ được dùng làm nguyên liệu đốt cháy chính của quá trình đó. Do đó lượng khí CO2 thải ra môi trường khi sử dụng bếp tiết kiệm sẽ được giảm xuống 95 % so với sử dụng bếp thường.

This paper describes work directed at characterizing the dynamic behaviour of a small gasifying fixed-bed biomass stove. The system comprises a primary gasification chamber, followed by a multi-stage secondary combustor which can allow for the considerable variation in quantity and calorific value of fuel gas produced by forming a series of flamelets which move along the length of the secondary combustor as a function of the local mixture ratio. The typical cycle time is about 60 minutes and once warmed up the unit is capable of operating with low emissions, providing appropriate guidelines are followed. Correlation of temperature and gas concentration measurements on the unit with velocity and flow visualization measurements on a perspex model of the secondary combustor show that improvements can be made to the flow patterns in the bottom of the secondary combustion chamber by reducing the size and shape of the recirculation zones formed and revising the location of the mid-section secondary air inlet. Control of the system is indicated using a simple measurement of temperature in the secondary combustor to determine appropriate air supply rates.

The stove is one technology that plays an important role in the utilization of energy at the household scale. The biomass stove studied was a blower system gasification stove. In the blower system, oxygen entering the combustion chamber flows continuously according to the needs of combustion. In this biomass gasification stove study, researchers will also use the biomass stove wall or thermal energy into kinetic energy for grinding blowers and charging systems. This study aims to obtain fuel by utilizing biomass or organic waste as biomass stove fuel and get the energy driving the blower and charging system by utilizing a thermoelectric generator system. biomass stoves used in this study use the principle method of Top-Lif Up Draft (T-LUD) Gasifier, a type of gasifier that matches the characteristics of biomass that has high volatile matter, where the stove is designed intended for biomass fuel from agricultural waste products and industry, boiling 1 kg of water is done using wood chips by varying the area of ​​the air flow door, which is 50%, 75%, and 100%. Can be analyzed Comparison of the performance of the biomass cooker stove and the power generated by the thermoelectric generator, at each door width of the air flow results are different, this is due to the mass of fuel consumption and fire temperature. After calculating the highest thermal efficiency results obtained in the area of ​​50% air flow ventilation and obtained power generated 1.83 watts with 100% ventilation flow door area using wood chips.

This study aims to characterize the combustion of the biomass stove filled with a porous medium for air pre-heating to enhance the biomass decomposition. An equivalence ratio, one of the important parameters for the combustion, was investigated to evaluate the completeness of the combustion process. Thermal efficiency was used as the indicator to reflect the performance of the biomass stove. Which was divided into two parts namely the pre-combustion (PCC) and the combustion chamber (CC). The CC volume was 28 liters for fuel storage, and it was insulated for reducing heat loss. The stove was made of 2 mm steel plate and the porous medium was a round-shape ceramic with a diameter of 10 mm. The boiling test was performed using corn cobs as a single solid fuel to boil water in the vessel. The temperature of the stove was measured using a thermocouple Type-K and a data recorder was used to collect the experimental data. The airflow rate was determined using an airflow meter and the fuel consumption rate was calculated using the aforementioned experimental data. Finally, the designed biomass stove will be demonstrated at the community to simultaneously enhance the community-scale energy and reduce the environmental issues.

This study aims to design a biomass stove as a solution for lack of LPG gas in the community in Batu Panjang, Rupat Island, Riau. The Quality Function Deployment (QFD) method is used in this study by elaborating consumer needs through public opinion needs (questionnaire survey) and elaboration of the characteristics of consumer needs. A House of Quality (HoQ) matrix was created to determine the technical characteristics for design analysis of biomass stove and designed using the Design for Manufacture and Assembly (DFMA). The result was a development of "Biomass Stove", which consists of a funnel for fuel, a fire funnel, a filter and an air chamber. The funnel chamber, which the fuel was made the insulation channel and the joining of the fire connector, forms an angle to increase the heat flow to funnel fuel and reduce the heat loss during cooking. The stove design is made safe, comfortable for users and environmentally friendly due to the existence of a filter and air chamber cover. The biomass stove was designed portable, and then it was light and easy to move around.
