Abstract
The invention provides a burner of a direct-injection type cooker combustor. The burner of the direct-injection type cooker combustor comprises a burner body and nozzles. An outer annular mixed gas cavity, a center gas inlet tube and a pre-mixed cavity are formed in the burner body. The outer annular mixed gas cavity is communicated with the pre-mixed cavity through a gas guiding hole formed in a partition plate. The lower end of the center gas inlet tube is fixedly connected with a center gas inlet hole in the partition plate. The gas guiding hole surrounds the center gas inlet hole. The lower end of the center gas inlet tube is communicated with the pre-mixed cavity. The nozzles are opposite to the center gas inlet hole and the gas guiding hole. The gas guiding hole is of a circular truncated cone shape. The nozzles are arranged on gas outlet holes formed in a nozzle base. The portion, located on the center of an annular gas inlet cavity, of a direct gas inlet tube is provided with gas outlet holes. The nozzle base is arranged in the pre-mixed cavity or the nozzle base is arranged below the pre-mixed cavity. Gas and air are mixed in advance in the pre-mixed cavity. Sufficient air is guaranteed. The gas and the air enter the outer annular mixed gas cavity to be further mixed after being compressed and released by the gas guiding hole, and therefore the purposes that the gas and the air are completely mixed, the gas is burned completely, and energy is saved are achieved.
