Document Type and Number:
WIPO Patent Application WO/2014/015550
Kind Code:
A1
Abstract:
A backfire-preventing biomass stove comprising a burner (30) and an electrical device (50). The electrical device (50) comprises a power supply (53), a material-feeding motor (51), and a blower (52). The burner (30) comprises a piece of inner-side upright board (31), a piece of outer-side oblique board (32), two pieces of lateral boards (33), and a section of material-feeding sleeve cylinder (35), a material-feeding cylinder (36), and a pusher (37) accommodated within the material-feeding cylinder (36) and the material-feeding sleeve cylinder (35). A gap (38) is formed between an outer end (351) of the material-feeding sleeve cylinder (35) and a material-discharging end (362) of the material-feeding sleeve cylinder (35). Several primary air supply holes (38) are provided above an upper position of the outer-side oblique board (32) and above upper positions of the two pieces of lateral boards (33). A closed primary air supply space (12) is formed below the burner (30), while a closed secondary air supply space (14) is formed above the burner (30). A closed backfire-preventing air supply space (16) is formed around the material-feeding sleeve cylinder (35). The primary air supply space (12), the secondary air supply space (14), and the backfire-preventing air supply space (16) are all supplied with air by the blower (52). The stove allows for effective prevention of backfire.
