It will cost you anywhere between 100 and 1,500 to convert your wood stove to a multifuel or gas stove. The actual cost will depend on the type of stove you have, the type of fuel you want to use, and the cost of labor in your area. If you have a basic wood stove, you can probably convert it to a multifuel stove for around 100.

The water remaining in the wood to be carbonised, must be evaporated in the kiln or pit and this energy must be provided by burning some of the wood itself which otherwise would be converted into useful charcoal. The first step in carbonization in the kiln is drying out of the wood at 100°C or below to zero moisture content.

A comparison of efficiency of conversion of natural gas, coal, and wood waste is shown in Figure 2. Conversion of coal to methanol, while considerably more efficient than that of waste wood, involves more processing facilities because of the greater amount of ash and sulfur (wood has no sulfur). Coal conversion to syngas is more efficient ...

Carbonization Process. In the carbonization process, coal, as a result of the thermal effect in an inert atmosphere and slow heating rate, undergoes structural modifications that produce a raw gas (known as COG, which amounts to around 25wt% of the coal charged) and a molecular rearrangement of the carbon cluster, the result of which is a highly carbonaceous and graphitizable coke.
