Liquid fuel self-sustaining combustion burner for flame synthesis

A liquid fuel self-sustaining combustion burner, comprising:

• a swirl-flow cylinder defining a swirl-flow chamber therein and comprising an open end;
• a central stabilizing column disposed in the swirl-flow chamber;
• a swirl-flow plate disposed at the open end of the swirl-flow cylinder, the swirl-flow plate being supported by the central stabilizing column, at least one swirl-flow outlet being defined in the swirl-flow plate;
• an atomizer disposed between the swirl-flow plate and the central stabilizing column, the atomizer comprising an atomizing nozzle;
• a tangential inlet tube mounted on the swirl-flow cylinder and fluid communicated with the swirl-flow chamber, an axial direction of the tangential inlet tube being tangential to an outer surface of a sidewall of the swirl-flow cylinder;
• a stable combustion cylinder defining a stable combustion chamber therein;
• a connecting rod;
• and
• a fixing bracket;
• wherein the open end of the swirl-flow cylinder extends into the stable combustion chamber, the atomizer is capable of atomizing and spraying a fuel into the stable combustion chamber for combustion, the tangential inlet tube is capable of introducing a first airflow into the swirl-flow chamber and allowing the airflow to advance spirally around the central stabilizing column, thereby forming a swirling airflow to reach the swirl-flow plate, the swirl-flow plate is capable of partially injecting the swirling airflow into the stable combustion chamber through the at least one swirl-flow outlet and allowing the swirling airflow to spirally advance in the stable combustion chamber, and the atomizing nozzle is configured to be located inside the swirling airflow;
• wherein the swirl-flow cylinder comprises a closed end opposite to the open end, the central stabilizing column is inserted into the swirl-flow chamber through the closed end, and the central stabilizing column is fixedly connected to the closed end, one end of the connecting rod is fixedly connected to the central stabilizing column, and the other end of the connecting rod is fixedly connected to the swirl-flow plate;
• wherein the fixing bracket is sleeved on one end of the central stabilizing column away from the closed end of the swirl-flow cylinder, and an outer side surface of the fixing bracket abuts against an inner surface of the sidewall of the swirl-flow cylinder, the connecting rod protrudes from the fixing bracket toward the swirl-flow plate, one end of the connecting rod is fixedly connected to the central stabilizing column through the fixing bracket.
