FGR® works as an efficient particulate filter, preferably delivered in a standard container, ready to plug in.
The system is modular and can be customized for heating installations between 100 and 1000 kW. A 10-feet container contains an FGR suitable up to c:a 500 kW. To fit larger heating systems, a 20 feet container is needed.
The product consists of a heat pump with cooling unit, condensation unit with heat exchanger and a control system. It is either mounted in a stand-alone small container, placed close to the boiler room, or inside existing boiler room.
Due to the high level of condensation, most of the particulate matter ends up in the condense water. But the smallest most dangerous particulates has a tendency not to stick to water and will remain in the flue gas flow. We have solved this by adding an air filter that will capture around 90% of the smallest as well. We have run time measurements showing a level below 20 mg/Nm3 particulate matter in the FGR chimney.
Maintenance of the FGR includes rinsing the heat exchanger in the same interval as boiler sweeping. The interval of air-filter replacement depends on the boiler load, but approximately once a month.
