Frequently Asked Questions
Is it a continuous or batch process?
Pyrocal CCT (Continuous Carbonization Technology) system is fully continuous and capable of running 24/7.
Is it an automated process?
Our systems typically use PLC controls, instruments and protection systems that allow push button start/stop and extended periods of unattended operation. Operators can view and control the systems via an internet connection.
Is it mobile?
The system can be configured to be fixed or relocatable.
What raw materials can be used?
Without pre-drying, most biomass based feedstocks with a lower heating value (NCV) greater than 11 MJ/kg. That typically means feedstocks with a moisture content of less than 30%. With pre-drying the limit on initial moisture content is around 78%.
Biomass contaminated by heavy metals, toxic compounds and “compounds of concern” such as pesticides, CCA and halogenated chemicals cannot be processed.
Do Pyrocal systems produce syngas / bio oil?
No. Pyrocal’s CCT process produces an off-gas which is not a syngas and is not suitable for running engines, except for large two stroke low speed diesel engines (typically 200 rpm).
How much biochar is produced, how much ash, how much oil?
The typical yield of biochar for biomass feedstocks is 25% on dry mass, however this varies depending on the feedstock and the bias of the operating system towards biochar or energy.
The system does not produce oil or any other condensates.
What do they cost?
Cost is influenced by feedstock preparation, heat recovery options and emissions control requirements. Contact us to discuss your requirements.
What are the maintenance intervals?
The major overhaul service interval is 8000 hours/one calendar year. Inspections and lubrication activities are recommended for every 250 hours/two calendar weeks of operation.
What is the maintenance cost?
Approximately 3.5% of the installed cost of the system, per annum, labour inclusive. Most of this is expended at the major service.
How many operators are required?
0.25 full time equivalent (FTE) for systems co-located to facilities producing the feedstock and utilising the heat that have automated feed handling and biochar outloading arrangements. For standalone systems not sharing operators with another facility, one full time operator is required.
Where do you manufacture and sell the equipment?
Pyrocal’s CCT system is manufactured in Australia and sold world-wide. Local certifications (e.g CE marking) are performed on a project by project basis.
