Surface Contact: Difference between revisions

[[Surface contact]] reactors are a key type of ATT ([[Advanced Thermal Treatment|advanced thermal treatment]]) reactor and are generally used in [[Pyrolysis|pyrolysis]] systems<ref>[https://ifrf.net/ifrf-blog/energy-from-waste-technologies-advanced-thermal-treatment-pyrolysis-and-gasification/ Energy-from-Waste Technologies]</ref>. The application of this technology is to maximise the rate of [[Pyrolysis|pyrolysis]]. These reactors can process only small-sized [[Waste|waste]] and so pre-treatment of [[Feedstock|feedstock]] is required. This process runs at high temperatures of 600-850°C and the small [[Feedstock|feedstock]] size results in high heating rates<ref>[https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/221035/pb13888-thermal-treatment-waste.pdf Advanced Thermal Treatment of MSW]</ref>.

An example of the application of this reactor type in waste-to-energy plants is Beston's [[Pyrolysis|pyrolysis]] plant which can process [[Waste|waste]] tyres, [[Waste|waste]] rubber, oil sludge, and [[Waste|waste]] [[Plastic|plastics]]. The chamber of this plant is heated to provide [[Surface contact]] and [[Pyrolysis|pyrolyze]] [[Feedstock|feedstock]] into industrial fuel oil, steel wire, and [[Flue Gas|combustible gas]]<ref>[https://www.bestongroup.net/waste-tyre-rubber-oil-sludge-prolysis-plant-for-sale/?gclid=CjwKCAjw_o-HBhAsEiwANqYhp0BOZyIXDZ2wC-79P6D0JoMW22ctMeKv1Jk09DoVJJAGz907c4g2eBoC9F8QAvD_BwE Beston Pyrolysis Plant]</ref>.
