Abstract

The invention discloses a fire distribution structure of a two-cavity direct injection burner. The fire distribution structure comprises a burner cap seat which is provided with an external fire ringand a center fire ring; the external fire ring is connected with an external ring burner cap in a covered manner; the center fire ring is connected with a center burner cap in a covered manner; an external ring gas inlet is formed in the position, corresponding to the external fire ring, of the bottom of the burner cap seat; the external ring gas inlet communicates with the external fire ring; a center gas inlet is formed in the bottom center of the burner cap seat; the center gas inlet communicates with the center fire ring through a plurality of center gas inlet channels formed in the periphery of the center gas inlet; the bottom of the center gas inlet is closed; and an inverted-cone-shaped gas-distributing cone is arranged at the parts, corresponding to the connecting parts of the center gas inlet and the center gas inlet channels, of the inner bottom of the center gas inlet. The gas-distributing cone can allow a gas mixture of air entering from the center gas inlet and gas to generate turbulence, the air is mixed with the gas fully, the gas mixture is uniformly conveyed to the center gas inlet channels, the center fire ring and the center burner cap, the gas mixing effect of the gas mixture entering the center burner cap is good, and sufficient combustion can be guaranteed.

Description

technical field [0001] The invention relates to a flame distribution structure of a double-cavity direct-injection burner. Background technique [0002] Chinese Patent Document No. CN1900593A discloses a burner with balanced gas distribution, which includes a gas seat with an air mixing pipe at the bottom and an inner fire cover and an outer fire cover arranged above the gas seat. An outer ring air groove and an inner ring air groove are provided, a gas passage is provided between the inner ring air groove and the outer ring air groove, and several outer air mixing passages separated from the gas passage are arranged between two adjacent gas passages , there is an inner air mixing channel between each of the outer air mixing channels and the inner fire cover. [0003] The burner adopts direct injection to form mixed gas and air supply, which can improve the combustion efficiency and make the combustion more complete. However, the structure of the inner fire cover has not be...
