Ecomb AB

The invention, now protected on all essential markets around the world, implicates a new concept for optimising the combustion process in boilers.

Not only because of standards and claims from the authorities but also from the companies own environmental policies.

By installing retractable tubes, equipped with nozzles, (Ecotubes) inside the boiler, secondary air can be added with high pressure and high speed improving the mixing of the gases. The result is a remarkable reduction of pollutants like nitrogen oxides, carbon monoxide and VOC (Volatile Organic Compounds) in the flue gas. At the same time the thermal efficiency increases which implies not only lower fuel costs but also a reduction of carbon dioxide, the main source to the greenhouse effect.

The purpose for ECOMB is to develop, market and supply the Ecotube-system as well as selling license rights.
