Horizontal Bed Kiln

Horizontal bed pyrolysis kiln


The pyrolysis kiln by CarbonZero decomposes carbon to various forms of biochar, humic and fulvic acid with an efficient, affordable and reliable technology.

The solution is designed to extract as much value as possible from biomass waste streams in a simple, reliable way, to enable carbon recycling. The device generates value by (a) producing biochar or torrefied biomass from nearly any feedstock, (b) condensing wood vinegar from the gas stream, (c) cracking and filtering the raw syngas remaining after condensation to produce clean syngas, (d) optionally burning the syngas in a genset to produce electricity, and (e) pre-processing biomass to be converted to humic and fulvic acid in a secondary process.
