Wood pellet-boiler, has short transverse edges provided at guiding surfaces transverse to exhaust gas flow direction, where surfaces produce exhaust gas burble, guide hot water and are arranged between heat exchanger surfaces

摘要

The boiler has a wire mesh filter (5) provided above a burner pot (20) and provided before a cylinder barrel structure (3) that includes an attachment piece. Guiding surfaces (4) are made of sheet metal, and short transverse edges (11) are provided at the surfaces transverse to an exhaust gas flow direction. The guiding surfaces produce an exhaust gas burble, guide hot water and are arranged between heat exchanger surfaces (16).
