Abstract

The invention discloses an efficient energy-gathering combustor which comprises a furnace end, a furnace end seat and a combustion seat. An inner injection tube and an outer injection tube on the furnace end are respectively connected to the bottom of the furnace end seat. A central fire cover is disposed on an inner-ring fuel gas outlet upper cover. A plurality of outer-ring fuel gas outlets using the inner-ring fuel gas outlet as center are evenly distributed on the periphery of the combustion seat. An outer fire cover covers on each outer-ring fuel gas outlet of the combustion seat, the outer fire cover forms an independent combustor, and a secondary air replenishing passage is formed at the center of each independent combustor. Each outer fire cover is cylindrical. An outer main fire hole communicated with a branch passage is formed on the upper side of the outer wall of each outer fire cover. An outer flame stabilizing hole communicated with the branch passage is formed in the lower side of the outer wall of each outer fire cover. Ignition holes annularly formed on the periphery of the outer side wall of the lower step of the central fire cover and the outer main fire hole, on the same horizontal position, on the outer side wall of each outer fire cover adjacent to the ignition holes do not have fire outlet holes, so that cross combustion of outer main fire and central fire can be avoided effectively, and phenomena such as insufficient combustion, insufficient secondary air replenishing, and flame lifting can be avoided.
