SUPER BLUE FLAME RICE HUSK GAS STOVE (BIOMASS GASIFIER STOVE)

The super low-cost, blue-flame rice husk gas stove was developed in
Indonesia by Engr. Alexis Belonio, Ir. Bima Tahar & Bonny Minang under PT. Minang Jordanindo Approtech in 2010.

Design objective: 

The goal was to provide households with an affordable clean-burning cooking device
using rice husks as fuel. The stove can be sold at a selling price of US$10 to US$15, very cheap compared to other stove models.

The stove consists of only few parts. It was designed and made so simple to maximise the use of cheap materials and to simplify the production using locally available resources.

Parts of the stove

The (3) basic parts of the stove model:

1. Casing - is made of tin can which is sold at a very low price from a Can Factory.
2. Reactor - can be subcontracted from a sheet metal manufacturer as well as the stove cover and the burner.
3. Fan - DC 12 volt, 2 watt supplies the required air to gasify rice husks. 

Flame Color/ Quality

The flame coming out of the burner is bluish in color, which indicates a
very clean gas. It has low black carbon emission of about 50 ug/m3 and below.
The CO2 emission is about 0.6 kg CO2 per kg ricehusks.

Performance: 

Results of the performance testing and evaluation using a water boiling test:

Fuel consumption: 400 grams/load
Ignition time: 1 minute
Operating time: 18 to 25 minutes of cooking
Boiling time: 13 minutes for 1.5 litres of water
Gasification rate: 72 kg/hr-m2
Fire zone rate: 2.2 cm per minute
Thermal efficiency: 20.2%
Power input: 4.56 kWt
Power output: 0.96 kWt

Additional features: 

• The intensity of the flame can be controlled
•  In case of power failure, the stove is adaptable to either a 9-volt rechargeable dry cell or a sealed lead acid battery from motorbike or from automobile.  
• The use of thermo-electric chip can also be adopted for the stove, if needed.

Other Benefits

•  In the users’ perspective, payback period for the stove is within a month as compared with kerosene or LPG stoves. 
•  A CO2 saving of 0.40 and 0.27 ton per year can be derived from the use of the stove against the use of kerosene and LPG fuel, respectively.
