This invention describes a new type of stove that in situ converts solid fuels into synthetic
(syn) gas and thereafter burns the gas cleanly to produce a bluish flame similar to gas
combustion of natural gas stoves. The types of solid fuel suitable as fuel include, but not
limited to, coal, charcoal, pelleted/briquetted sawdust, rice husk and other agro-wastes
products. To increase the versatility of the stove an automatic control system is designed for the automatic supply of air.
solid fuel gasifier stove comprising an upper part and a lower part.
A solid fuel gasifier stove of claim 1 in which the two parts are joined to maintain an air tight fit.
A solid fuel gasifier stove of claim 1 in which the lower part houses the ashes and can be disengaged to dump the ashes.
A solid fuel gasifier stove of claim 1 in which an air intake assembly is attached to the lower part
A solid fuel gasifier stove of claim 1 in which the upper part contains the grate which serves to hold the solid fuel while allowing the ashes to pass through.
A solid fuel gasifier stove of claim 6 in which air is admitted into the combustion and gasification chamber through the grate.
A solid fuel gasifier stove of claim 1 in which the upper part walls are lined with refractory materials.
A solid fuel gasifier stove of claim 1 which is integrated with a burner and a syngas filter materials.
A solid fuel gasifier stove of claim 9 in which the gas burner consists of a series of pen ended steel tubes perforated at the sides.
A solid fuel gasifier stove of claim 10 in which air is admitted into the burner through the open ends of the tubes then through the perforations to mix with the generated syngas from the combustion and gasification chamber for complete combustion.
A solid fuel gasifier stove of claim 1 in which the air intake into the combustion and gasification chamber is electronically controlled.
A solid fuel gasifier stove of claim 12 in which the said control of the air intake is achieved by a low power switched - mode DC power circuitry
A solid fuel gasifier stove of claim 2 in which a thermoelectric generator (TEG) device can be integrated to power the blower fan and at the same time provide power for cellphones for rural dwellers
Significance of Invention
We have described a new type of stove that coverts various types of solid fuel into synthetic gas for a clean combustion. The invention also includes an automatic control system to supplies air to the combustion chambers to provide regulation for combustion. The invention is a vast improvement on the existing liquid (kerosene) or charcoal stoves, in terms of performance and clean combustion.
Environmental Friendliness and Merits over Existing Stoves
Ability to utilize several types of cheap solid fuels, such as agro-waste, saw dust, coal, etc.This makes it environmentally friendly and cheap when compared to cost of kerosene
Combustion can be controlled automatically and a pure blue flame achieved
Ease of ignition and operation
Suitable for rural areas and urban areas
The stove can be made more functional by adding a Thermo-Electric Generation (TEG) device that will enable rural dwellers charge their cell phones.
Ease of manufacturing, using locally available materials
