Our Range

Pyrocal offer three sizes of BiGchar Continuous Carbonisers. Each of these can be adapted to optimise the production of carbonised products (chars) and/or heat. The table below describes the potential for heat from each model systems. Char production from these systems can be expected to range between 5 and 35% of dry feed, depending on the biomass characteristics and machine settings.

All of our models can be configured as fixed, relocatable or mobile plants. Units can be ganged to provide higher throughputs and processing redundancy.

All of our models can be configured to comply with a wide range of emissions standards.

The chars produced by our systems typically have a high porosity and surface area, however Pyrocal can also offer integrated sizing, conditioning, activation, functionalisation, de-ashing and coking equipment processes to produce a wide range of carbon based products.

Nominal footprint of supplied equipment (excl. biomass & char handling) m (ft) 6 x 2.3 (18 x 7'6") 9 x 2.7 (30 x 9) 9 x 2.7 (30 x 9)


Hot water production requires the addition of a heat exchanger, which is not included in the standard scope.

Actual performance is subject to the specific type and quality of biomass provided.

* Value available for direct heating. Values depend on biomass and operating mode (char or heat bias). Please consult Pyrocal.
