Peripheral Equipment

A screw (auger) conveyor is a rotating helical blade inside a trough or tube that moves the biomass feedstock steadily from one point to another.

It is typically used for conveying dried feedstock to the pyrolysis reactor in horizontal or vertical directions. The exact specifications depend on the site layout and feedstock properties. However, they typically have a limitation on the length and are preferred for short distance transport of feedstock.

A belt conveyor is a continuous moving belt supported by rollers that carries loose biomass feedstock over longer distances.

It is typically used for conveying wet feedstock to the dryers. The belt conveying allows for transportation over longer distances. The exact specifications depend on the site layout and feedstock properties.

A chain-drag conveyor uses heavy-duty chains with attached flights to drag biomass through an enclosed trough.

It is typically used to move dried feedstock to the pyrolysis reactor or quenched biochar out of the reactor. It’s great for moving coarse, hot, or abrasive material over medium distances while keeping dust contained. The exact specifications depend on the conveyed material's properties and throughput (kg/hr).

Walking Floor systems are a type of feeding mechanism where biomass is fed via a hydraulic slatted system that "moves" the floor to deliver biomass uniformly. It can come in a 20 ft or 40 ft container system or as custom moving floor system in bunkers.

The wet feedstock is hauled into the containers or bunkers and the moving floors deliver the feedstock to the dryers via discharge chute conveyors in a controlled manner. The exact specifications depend on the required throughput (kg/hr or t/hr) and the feedstock properties.

A rotary feeder is a type of feeding mechanism that consists of a rotating arm in a bunker. It rotates uniformly to deliver biomass through a discharge chute.

It is typically used to feed dried feedstock to the pyrolysis reactor via screw conveyors fitted in the discharge chutes. While they're good for high density feedstocks like woodchip, they may not be suitable for low density feedstocks like AD digestate. The exact specifications depend on the required throughput (kg/hr or t/hr) and the feedstock properties.

A bunker feeder is a type of feeding mechanism which consists of a moving overhead system with a scraper blade that sweeps biomass across a bunker floor and pushes it toward a discharge point.

The wet feedstock is hauled into the containers or bunkers and the overhead moving arms deliver the feedstock to the dryers via discharge chute conveyors in a controlled manner. The exact specifications depend on the required throughput (kg/hr or t/hr) and the feedstock properties.

A drum (rotary) dryer is a large rotating cylinder with internal flights that lift and shower material through a heated gas stream to evaporate moisture.

It is typically used to dry biomass feedstock to the required moisture content levels.

Programmable Logic Controller (PLC) cabinets house power supplies, I/O modules, motor starters, wirings, etc that run the machines. They protect and organise control hardware for reliable and safe operation.

It acts as the brain of the pyrolysis machine and the entire plant, allowing us to not only control every individual component but also decide how they will interact with each other to optimise throughput. The specifications of the cabinet is usually decided by enclosure rating, I/O count, power/UPS capacity, cooling needs, physical size and required certifications.

Human Machine Interaction (HMI) screens are the operator touchscreens or panel displays used to monitor and control the process, set recipes, view alarms and run manual overrides. Often HMI screens come integrated with the PLC module. Their specifications are typically decided based on required screen size & resolution, touch type, ingress rating (IP), connectivity (Ethernet/Modbus/OPC), panel/flush mount options and compatibility with the PLC stack.

A heat exchanger is used to transfer heat between process streams (hot flue gas, hot oil, vapour or cooling water) to recover energy.

The combusted hot flue gases carry significant amount of heat energy that is difficult to tap as is. Heat exchangers capture this energy and transfer it to water. It can then be utilised as per the site's requirements. The exact specifications of the heat exchanger depend on the amount of energy coming out from the flue gases and the desired efficiency and budgetary constraints.

An Organic Rankine Cycle (ORC) unit converts heat into electricity using an organic working fluid and a turbo-expander.

The energy captured from the flue gases, after being captured by the heat exchanger can be further converted into electricity using an ORC unit. The exact specifications of the ORC unit depend on the amount of energy captured by the heat exchanger and the desired efficiency and budgetary constraints.

A wet scrubber uses a liquid (usually water) spray or packed-bed contact to capture soluble gases, acid vapours and fine particulates from pyrolysis flue gas. It’s used where efficient gas cooling and high removal of condensibles or soluble pollutants is needed before emission or further treatment.

The flue gases need to cleaned before being released into the atmosphere. Wet scrubbers capture WHAT GASES and are essential for adhering to the emission limits set by authorities. The exact specifications of the wet scrubber depend on the flow rate of the flue gas, its composition and properties and the method of scrubbing.

A cyclone separator uses centrifugal force to remove coarse particles and char from hot gases before they reach filters or heat recovery. It’s rugged, low-maintenance, and ideal as a first-stage solids interceptor in a pyrolysis line.

The exact specifications of the wet scrubber depend on the flow rate of the flue gas, its composition and properties and the method of scrubbing.

Flue stacks and ductings are steel bodies that safely convey exhaust gases from the reactor through cleaning equipment and out to the atmosphere.

The exact specifications of the ductings and flue stacks depend on the exhaust gas flow and temperature, required stack height (dispersion/regulatory), duct diameter & layout, material (corrosion/temperature resistant), etc

A chain-drag conveyor uses heavy-duty chains with attached flights to drag biomass through an enclosed trough.

It is typically used to move dried feedstock to the pyrolysis reactor or quenched biochar out of the reactor. It’s great for moving coarse, hot, or abrasive material over medium distances while keeping dust contained. The exact specifications depend on the conveyed material's properties and throughput (kg/hr)

A bagging system is used to fill, seal and label finished products into bags of different size options. The quenched biochar can be directly bagged in required size and format (50L, small consumer bags, or bulk sacks) for retail or bulk dispatch. It’s used to automate packing, control weights, and speed up dispatch.

The exact specifications of the bagging system will depend on the discharge rate, sizing and labelling requirements.
