What ECOMB does
ECOMB AB (publ) is a Södertälje-headquartered, publicly listed Swedish engineering firm (NGM Nordic SME, ticker ECOM) founded in 1992 that develops, markets and supplies the patented Ecotube combustion-optimization system to operators of industrial and utility boilers. The core technology consists of retractable tubes fitted with nozzles that are installed inside a boiler to inject secondary air at high pressure and velocity, improving mixing of combustion gases to reduce NOx (30–70%), CO (10–90%) and VOC emissions while raising thermal efficiency and boiler load capacity. The product family has been extended to Ecotube DOS (Deep Oxygen Staging) for precision oxygen injection and the conceptual Ecotube Zero oxyfuel platform that recycles flue gas to enable near-zero atmospheric emissions and a step-change reduction in CCS cost. ECOMB also offers complementary modules (SNCR urea injection, FGR) and services (parameter analyses at ~30–100 TSEK and furnace inspections using a proprietary 45mm water-cooled camera) that double as the first step of the sales funnel.
The business model is project-based: revenue comes primarily from complete Ecotube system deliveries to existing boilers (5–20 MSEK per installation per disclosed contracts including 15.5 MSEK Reunion, 8 MSEK Grenoble, 6 MSEK Poland and 20 MSEK Martinique) plus licensing of IP, spare parts and the entry-point engineering services. Distribution is partner-led internationally — territory partners (BioC in UK, ICS in Poland, AIXPROCESS and KS Ingenieurbüro in Germany) and a 2021 co-operative partnership with RJM International for Scandinavia — with direct sales engagement in Sweden. Customers span district heating, waste-to-energy, pulp & paper, sugar processing and biomass power across Sweden, France, the UK, the Netherlands, Poland, Finland, Germany, Italy, Reunion, Martinique, the USA and China, with 38 completed projects and 72 installed Ecotubes over the company's 30+ year history. A 2016-incubated subsidiary, ECOMB Ocean Recycle AB, extends the oxygenation IP into lake/ocean restoration and PFAS remediation, and recent strategic positioning (a 2026 NDA with a global industrial gas company, alignment with the STEGRA hydrogen project, and an Energimyndigheten grant for Ecotube DOS) targets the hydrogen and carbon-capture markets.

Product offeringCore offering
ECOMB AB designs, markets and supplies the patented Ecotube System — retractable tubes with nozzles installed inside industrial boilers that inject secondary air at high pressure and speed to improve gas mixing. The system reduces NOx, CO and VOC emissions while increasing thermal efficiency, and is delivered as full hardware installations (5–20 MSEK) bundled with engineering services (parameter analyses, CFD simulations, furnace inspections, commissioning). The portfolio has been extended to Ecotube DOS (oxygen injection), Ecotube Zero (oxyfuel with full flue gas recirculation for near-zero emissions and cheaper CCS), complementary SNCR and FGR modules, and a proprietary water-cooled inspection camera, plus licensing of the technology to international partners.
Product overview
ECOMB offers a suite of combustion optimization products and services centered on the Ecotube System. The core Ecotube System is a patented technology using retractable tubes installed inside boilers to inject secondary air at high pressure and speed, reducing NOx, CO, and VOC emissions while improving thermal efficiency. This platform has been extended into advanced variants: Ecotube DOS (Deep Oxygen Staging) for precision oxygen injection, and Ecotube Zero, an oxyfuel-based concept that recycles all flue gas back to the boiler, enabling near-zero emissions and significantly cheaper CCS. ECOMB also provides complementary modules including SNCR (urea injection) and FGR (flue gas recirculation), as well as consultancy services such as Furnace Inspection using proprietary water-cooled cameras and Parameter Analysis as the first step in its sales process. The company's subsidiary ECOMB Ocean Recycle addresses water remediation. The Ecotube System has been installed in approximately 38 completed projects across 72 installed Ecotubes.

Products and services
- Ecotube System Patented combustion optimization system of retractable tubes (Ecotubes) equipped with nozzles installed inside industrial boilers to inject secondary air at high pressure and speed, improving gas mixing to reduce NOx, CO and VOC emissions and increase thermal efficiency; sold as complete hardware projects (5–20 MSEK) to boiler operators.
- Ecotube Zero Advanced oxyfuel-based Ecotube concept in which all flue gas is recirculated to the boiler, eliminating chimney emissions and substantially reducing the cost of downstream Carbon Capture and Storage (CCS) by substituting nitrogen with CO2 in the combustion process; aimed at industrial operators considering carbon capture.
- Ecotube DOS (Deep Oxygen Staging) Ecotube-based oxygen injection technology for boilers that enables more precise delivery of oxygen to increase output and further reduce emissions; serves as the bridge between the conventional Ecotube retrofit and the Ecotube Zero oxyfuel system, and is the technology connecting ECOMB to the green-hydrogen economy by consuming byproduct oxygen.
- Parameter Analysis (Parameteranalys) Initial combustion engineering study (priced around 30 TSEK) analyzing how fuel quality, furnace temperature, air flows and emissions interact across operating conditions; serves as the first step in ECOMB's sales funnel, with approximately half of parameter analyses converting into subsequent Ecotube contracts.
- Furnace Inspection (Eldstadsinspektion) Inspection service using ECOMB's proprietary ultra-compact (45mm diameter) water-cooled camera for in-furnace visualization during operation; priced around 35 TSEK for typical waste-boiler visual documentation; used for tube-damage inspection, corrosion monitoring, and combustion-condition assessment.
- Ecotube SNCR Integration (Selective Non-Catalytic Reduction) Standalone SNCR product that uses the Ecotube's high-pressure air to distribute urea/ammonia efficiently into the furnace for further NOx reduction beyond what air-staging alone can achieve; sold as a combined hardware-and-chemical system to boiler operators.
- FGR (Flue Gas Recirculation) Flue gas recirculation hardware system installed alongside SNCR or Ecotube Systems to reintroduce a portion of flue gas into the combustion process in order to optimize for low-NOx combustion.
- Combined Combustion & Emissions Technology Packages Joint technology packages combining ECOMB's Ecotube emissions-reduction systems with partner technologies (RJM International combustion solutions, IGS, PowerPlus) into comprehensive combustion-plant offerings delivered into Scandinavia and other partner markets.
- Ecotube Technology License Rights Sale of license rights for the Ecotube technology to international markets through partnerships, enabling licensees to deploy and operate Ecotube systems in territories covered by the partnership.
- Spare Parts and Replacement Equipment Sale of replacement Ecotubes, cooling systems, pumps, fans and other auxiliary equipment to existing customers to maintain and refresh the installed Ecotube base.
- ECOMB Ocean Recycle Wholly-owned subsidiary of ECOMB AB that oxygenates over-fertilized lakes and seas with dead bottoms using a proprietary mobile technology, while simultaneously collecting PFAS for destruction from drinking water sources and contaminated leachate ponds.
