What Greens Combustion does
Greens Combustion Limited is a privately held industrial combustion OEM founded in 2011 and headquartered in Poole, United Kingdom, with research and development facilities in southern Italy and manufacturing reach through sister company AFG Combustion in India (parent HS Group of Companies). The company designs and manufactures low NOx burners, flares, thermal oxidisers, and incineration systems for the refining, gas processing, petrochemical, and fertiliser industries, with installations delivered to customers in more than sixty countries. Its core technology is grounded in physical combustion engineering rather than software: state-of-the-art hydrogen and ammonia test rigs in Italy (including 4MW ammonia firing capability) and proprietary Flare-in-a-Box emissions testing enable development and validation of 100% hydrogen-capable burners (under license from Honeywell UOP Callidus), smokeless ammonia flares, and low-emission thermal oxidiser packages.
The business operates across multiple revenue streams: one-time equipment sales (burners, flares, thermal equipment, ignition systems) into large capital projects, recurring aftermarket support including spare parts and replacement components, professional services covering testing and commissioning (FAT and on-site) plus multi-team training, and licensing royalties from the exclusive Honeywell UOP Callidus license that covers Europe, Africa, India, and Asia. Go-to-market is enterprise field sales with technical specialists, supported by a global agent network trained at the Italian test facility, with major end customers including Saudi Aramco (approved vendor since September 2024) and large Middle Eastern and European polyolefin complexes. Pricing is quote-based and project-specific, with no public list pricing.
