VERTICAL PELLET BURNER PRACTICABLE FOR VERTICAL-FLOW PETROL BOILERS

摘要

Novelty: a vertical pellet burner practicable for vertical-flow petrol boilers is disclosed. Constitution: an external shell 1 whereto a detachable cleaning drawer 3 having the combustion vessel in the middle and a recess 9 corresponding to the external shell’s 1 for accommodating the housing of the burner’s photocell 10 is adapted. Holding is realized by screws 4. Vertical recesses 7 set at the front side 3 assisting the different application of the supply screw 8. A centrifugal ventilator 11 is located at the rear part of the burner. A thermal resistance 12 is positioned in the interior of the burner to assist the ignition of the combustible material. The combustion vessel 6 bears apertures 15 for the passage of the combustion oxygen; correspondingly, apertures 16 also exist at the lower part to allow the ash release. A pellet-storing and -supplying cistern 21 is potentially placed in the vertical pellet supply mode while in the inclined supply mode an independent container is required. The artificial draught is ensured by the centrifugal absorber 22 operated by the electric motor 23.
