Carbonizing Furnace (patented)
The charcoal having carbon purity of 80% or above can be produced.
In case of carbonizing at a low temperature, pyroligneous acid and wood tar will be generated in
addition to charcoal. These impurities will cause the serious trouble of blockades of piping, etc..
In order to solve this serious trouble, a carbonization furnace must be constantly operated at the
temperature of 1200 ℃(2192 °F). The feature of TESNA's Carbonizing Furnace is to provide the heat storage
pot of heat resisting steel which can be maintained at the temperature of around 1000 ℃(1832 °F).
By the combustion of wood tips in the furnace, the internal temperature of the furnace is risen up to
1200 ℃(2192 °F), and the carbonizing furnace is allowed the operation temperature of 1200 ℃(2192 °F).
Reforming Furnace (patented)
Water gas of 60% of hydrogen content is generated.
Hydrogen concentration is governed by the temperature at the part where the charcoal and steam
are contacted and mixed in the Reforming Furnace. Therefore, it is necessary to uniformly stabilize
the temperature of this part. In this furnace, the temperature control is realized to provide the heat
storage pot and to supply the high temperature gas from the carbonizing furnace.
Biomass Gasification Unit (patented)
This is biomass gasification equipment which generates water gas after carbonizing the biomass.
It can be prevented to stick the unreacted residue in the equipment by uniformly becoming
stabilized the temperature of thermal decomposition and gasification furnaces with less heat loss by
developing two (2) patented furnaces mentioned the above.
Thereby, a miniaturization can be realized.
