Wood pellet burner BIOTERMEC 100.
Pellet burner consists of a burner body (which is to be mounted on the lower boiler door) and a screw-feeding system (which is put in the pellet stock beside the boiler). Flexible plastic tube is used to connect the two parts.
The control panel of the burner is on the front side of the burner body. Burner works automatically and can be programmed for each day in a week separately.
Unlike other products on the (Serbian) market, BIOTERMEC pellet burner has two feeders (controlled by two different motors). One is the main feeder that transports pellets to the burner body from the pellet storage. The other lies inside the burner and facilitates pellet feedind process to the boiler. It also acts as a protection from backfire.
BIOTERMEC 100 also has an automatic scrap tool for mechanical cleaning of the burner tube.
