Alpha improved wood gas stoves works on the principal of Gasification. By using a gasification solution for combustion of biomass heat transfer characteristics are improved greatly. The gasification / combustion process runs via two step process, whereby the biomass is gasified first with the resulting gas then combusted .
Air is drawn through a bed of burning wood which consumes volatiles. The gas then passes trough the resulting charcoal and is reduced to a low energy fuel gas.
Essentially due to thermo-chemical processes such as pyrolysis, combustion and reduction, gives wood gas stove high efficiency.
In Alpha wood gas stove biomass is burned with insufficient air in a gasifier, thus it makes producer gas containing primarily CO, H2, CO2, H2O and CH4. The charcoal then further reduces the CO2 and H2O combustion products back to CO and H2 fuel .
Our wood gas stove operates on correct air/ fuel ration thus it produces maximum flame temperature. The emissions from the close coupled gasifier burner are quite low and the stove can be operated indoors.
It will generate respectively 3 to 5kw of clean heat depending upon the biomass. This heat is equal to electrical hot plate.
In start up, wood gas gasifier is filled to nearly top with biomass. Fire is started on the top with dry leaves, grass or any thing like waste paper. Once the tinder is started, the air flow is started on low. With-in 30 seconds to 1 minute, it is turned on to full power and will run normally until all the fuel is consumed. A clean yellow- blue gas flame just like Natural gas is produced as air gasifies the charcoal to CO which gives hotter temperature at the grate.
If longer cooking is required, more fuel can be added judiciously in an updraft mode in which charcoal combustion supplies heat to pyrolysis the new fuel for gasification.
Our design reduce wood consumption through greater efficiency which in return reduces the time and cost for the user of the wood gas stoves.
Alpha’s wood gas stove is light enough and portable yet it is a well deign small gasifier which has the excellent heat transfer to the pot. It is large enough to cook a proper meal for a household of 4-6 persons.
The wood gas stove will bring a liter of water to boil in 4 minutes and can be turned down to the simmer level for longer cooking and increased efficiency.
All current wood cooking stoves require the user to blow on the fire with a small pipe for an extended period before the fire is ready for cooking. This can be especially taxing when trying to start a fire with damp wood during monsoon season. Alpha wood gas stove user does not have to do this, as fan is supplying combustion air in the correct amount to get the fire started. Full flame will be visible in less than 1 minute and effortless.
There is no major set up required. The unit comes ready to go. Fill the wood and it is ready to do the cooking.
This is a very low maintenance device with simple operation. There are no skills required in operations .
As our stove operates on clean combustion of wood with consistent heat output on gasification principles it has a blue flame and very little smoke in the beginning at the start of fire only. The complete combustion also eliminates polluting byproducts.
Metal stove walls keep themselves cooler than fuel, since they are typically free to radiate to the outside and conduct the heat away
Aluminum reflector panels are used inside the stove to reflect infrared heat back to the fire – increasing efficiency and decreasing outside metal temperatures.
