Clean gas stove 'Made in Vietnam' environment

The new type of stove built by the amateur inventor Bui Trong Tuan in Phu Tho is considered a new solution while saving and contributing to clean the environment.

The work of 'Stove without smoke' of Science Department, Vietnam Television Station won 1 in 2 first prizes of Science and Technology Press in 2012 out of 21 prizes of all kinds voted from 591 works. participation.

This documentary 'Smokeless straw stove' is about 9 minutes long, introducing the product of saving and clean gasification kitchen of an amateur inventor Bui Trong Tuan in Ho Chi Minh City. Viet Tri, Phu Tho province.

According to the film's author, this is a new type of stove, using burning materials as agricultural waste such as: straw, stems, sawdust, sugarcane and corn residues . but there is no soot and flame on the fire as strong as gas stove, infrared stove.

Stoves do not consume too much fuel but high cooking efficiency. Using cheap, easy-to-find materials, contributing to reducing environmental pollution due to straw burning, widespread agricultural waste of people today.

The housewife is operating a smoke-free straw stove.

The product is very suitable for the cooking needs of households and especially with small production facilities in rural areas that need to cook continuously, while using gas cookers is extremely expensive (according to VTV2 / VTV).

In terms of technology content, the author of the invention said: Gasification kitchen is produced based on the principle of aerodynamics, heat transfer through the use of complete air harmony between air and steam to prevent the production. produces tar, which extends the combustion time without ash and soot. With a recirculating technique, it compresses the flame to increase the thermal radiation, improving the thermal efficiency to the utmost, making the combustion completely clean with high productivity.

Gas stove includes parts: fuel tanks, gas and direct burners, clean filtration equipment, pipes and stoves. Fuel tank is made of steel, inside is a fire-resistant special intestine. Material is put into the gas volume chamber of 0.3 cubic meters.

After applying desiccated desiccation and oxidation reaction, a gaseous gas is produced with the help of nitrogen and oxygen. The kitchen features an input fuel that ignites and produces CO (carbon dioxide), CH4 (Methane), H (Hydrogen), CH3CH3 (Ethane) .

All of this exhaust gas is automatically collected into the separator system through the following steps: equipment for removing tar, smoke, ash, steam, thereby creating a clean gas, then passing through the gas pipe to the kitchen surface and transformed into infrared heat radiation.

The infrared ray itself has a source of energy that does not need to be derived from air, it itself has very strong penetrating power, so the heat is greatly increased, the energy conversion efficiency is enhanced many times. compared to direct burning materials.

The use of the kitchen is also very simple. Users put fuel into the gas tank and cover it. Open valves according to instructions and lighters (like gas stoves). Cooking can increase or decrease the fire on the stove by adjusting the fan speed or adjusting the kitchen lock.

In fact, if given 2kg of fuel, it can burn about 3 hours; If you give 10kg of fuel, you only need to burn once, after use, turn off the fan, close the compost valve and use the next 7 days. Usually 2 to 3 days of refueling once, 5 to 7 days of discharge once. Ordinary families only need 2 - 3kg of fuel to meet the daily needs, saving up to 70% compared to regular kitchens (according to network tietkiemnangluong).

If you put 2kg of fuel, you can burn for about 3 hours; 10kg of fuel only needs to be burned once, after use, turn off the fan, close the compost valve and use the next 7 days. Normally 2 - 3 days of refueling once, 5 - 7 days of discharge once.

The science and technology initiative of the inventor Bui Trong Tuan was granted an exclusive patent at the National Office of Intellectual Property, Ministry of Science and Technology.
