Top-intake three-fire-ring high-power burner capable of adjusting primary air

Abstract

The invention discloses a top-intake three-fire-ring high-power burner capable of adjusting primary air. The top-intake three-fire-ring high-power burner comprises a burner head, a fire distributor seat, a center burner cap, an inner ring burner cap and an outer ring burner cap; the burner head comprises an air and gas premixing cavity, a center gas outlet tube, a center gas inlet tube, an inner ring mixing cavity, an inner ring air outlet connector, an outer ring mixing cavity and an outer ring air outlet connector; a gas inlet groove is formed in the center gas outlet tube; a next-time air guide groove communicates with the gas inlet groove; a last-time air guide groove of a lower opening is formed in the lower surface of a disc body of the fire distributor seat; the last-time air guidegroove of the lower opening is intersected with a center gas inlet connector; a flow stabilization plate is arranged at the rear part of the air and gas premixing cavity; and the last-time air guide groove and a next-time air guide groove form a primary air guide channel. With the arrangement of a baffle plate, the primary air for inner ring fire and outer ring fire are sufficient; and with the arrangement of the center primary air guide channel, the primary air for center fire is sufficient, so that the emission of carbon monoxide is lowered and energy efficiency is improved.
