Combustion plants worldwide face growing pressure to reduce emissions while keeping operating costs under control. Stricter regulations and environmental commitments make improvements more urgent. We identify your boiler's operation today, all key combustion parameters are assessed and reviewed/analysed in the first phase.

Our own developed Ecotube System reduces emissions, improve efficiency and lower operating costs in boilers fired with all kinds of fuels. Installations carried out for boilers ranging from 10 to 270 MWth. Founded in 1992, ECOMB brings decades of experience in combustion optimisation. We design, market and supply the Ecotube System and also offer licensing opportunities.

The Ecotube System uses water-cooled retractable lances equipped with nozzles for injection of combustion air and de-NOx agents, such as ammonia or urea, into the furnace with high pressure and velocity. OFA and SNCR are combined in one system. Gas mixing is significantly improved resulting in reduced emissions of nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs) as well as keeping the ammonia-slip low.

Ecotube DOS (Deep Oxygen Staging) is an add-on technology where pure oxygen is injected through the Ecotubes. The aim is to increase boiler load, further reduce NOx emissions and improve combustion efficiency.

Ecotube Zero is ECOMB's oxyfuel combustion concept. All combustion air is substituted with oxygen-enriched recirculated flue gas. The CO₂ concentration in the flue gas will be dramatically increased, from 13-15 vol-% up to 90 vol-%, making CCS significantly more cost-effective - both CAPEX and OPEX will be significantly reduced. In the ultimate solution the stack will be shut-down - Zero emissions.
