USE FOR A BOILER SYSTEM, BOILER SYSTEM AND METHOD FOR OPERATING THE BOILER SYSTEM

摘要

The flame tube (21) of the burner (22) extends through the boiler door (23). The combustion chamber (24) of the boiler (25) is limited by a heat exchanger (26) with its outer walls (27) and by the rear wall of the boiler (28). The heat exchanger houses the heat exchange pipes (29) through which water to be heated flows. The water inlet (30) and outlet (31) are connected at the side. The insert (1) is centrally arranged in the combustion chamber so that the centreline of the flame coincides with its centreline, and is positioned on a locator comprising three bearing pins. The flame (34) starts shortly behind the flame tube and burns in the flow direction. Between the flame tube and the insert is a space (35) acting as a suction area (36). A part of the gas is recirculated via the suction area through the inlet aperture and through the injection openings (6) in the insert.
