A variety of machines can be used for biomass pyrolysis, with the most common being rotary kiln reactors and fluidized bed reactors. Rotary kiln reactors are cylindrical and rotate around a central axis to evenly distribute heat to the biomass. Fluidized bed reactors use a stream of air or gas to fluidize the biomass, providing even heat distribution and flexibility in feedstock. Both types of reactors are equipped with safety and control systems, including temperature and pressure control, to ensure safe and efficient operation. Other types of machines used for pyrolysis include screw pyrolysis reactors, vibrating pyrolysis reactors, and microwave pyrolysis reactors.
The heart of the pyrolysis process is the reactor, where all reactions occur. For flash pyrolysis, special reactors are required, with an oxygen-free atmosphere and a temperature range between 475 and 550°C. The solid behaves like a liquid when the gas flows through the bed. Pyrolytic reactors are designed to maximize the main product of pyrolysis, bio-oil. Common types of reactors include fluidized bed (bubbling and circulating), fixed bed, jet bed, rotary cylinder, cyclonic reactor, rotary cone, and others. Reactors can be classified into batch systems or continuous systems (continuous flow of biomass and continuous collection of products).
Fixed bed pyrolysis systems are simple, reliable, and proven for fuels that are relatively uniform in size and have a low content of coal fines. They consist of a reactor with a gas cooling and cleaning system and were traditionally used to produce charcoal. Fixed bed reactors generally function with high carbon preservation, low gas velocity, and low residue conveyed over a long solid residence time. A major problem of fixed bed reactors is the formation of tar, although recent advancements in thermal and catalytic conversion of tar have provided feasible opportunities for tar confiscation.
