The copyrolysis of coal and biomass has proven to be a promising route to produce liquid and gaseous fuels as well as specific valueadded chemicals while contributing to mitigating CO 2 emissions. The interactions between the coprocessed feedstocks, however, need to be elucidated to support the development of such a thermochemical conversion process.

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.

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.
