Abstract: 본 발명은, 액체와 기체가 혼합 분사될 수 있도록 구비된 동축형 인젝터에 관한 것으로, 액체가 유동 분사되는 액체 분사관; 상기 액체 분사관을 감싸도록 구비된 케이싱; 및, 상기 케이싱의 내부로 기체가 주입될 수 있도록 상기 케이싱에 구비된 기체 주입구;를 포함하며, 상기 케이싱의 내부에는 상기 액체 분사관으로부터 분사되는 액체가 기체와 혼합되는 혼합실이 구비되고, 상기 혼합실은 상기 액체 분사관의 외주면으로부터 이격된 다공성 재질의 격벽에 의해 구획된 것을 특징으로 한다.
이에 따라, 액체 제트의 유량이 대유량일 경우에도 동축형 인젝터의 분무 중심에서의 혼합 및 미립화 효율이 향상될 수 있다.

Abstract: PURPOSE: A two stages shear coaxial injector for enhancing arrival efficiency and atomized performance is provided to enhance atomizing performance. CONSTITUTION: A two stages shear coaxial injector comprises a nozzle body(10), a liquid nozzle(20), a first step gas nozzle(30), and a second end gas nozzle(40). The liquid nozzle is installed in the nozzle body. The first step gas nozzle is located on coaxial of the liquid nozzle. The first step gas nozzle atomizes the liquid emitted from the liquid nozzle. The second step gas nozzle is located on the coaxial of the liquid nozzle. The second step gas nozzle re-atomizes the liquid. Between a spraying unit of the second stage gas nozzle and the outer periphery of the tip of the first stage nozzle, a circular gap is formed.

Abstract: PURPOSE: A pressure compensated flame visualizing device of a high-pressure combustor and a pressure compensating method thereof are provided to increase the pressure of a combustor to be visualized through the same area of an observation window. CONSTITUTION: A pressure compensated flame visualizing device of a high-pressure combustor comprises a pressure compensation part(1) and a pressure control part. The pressure compensation part is formed on one side of a first observation window(3) of a combustor and provides pressure at a specified rate to the pressure of the combustor. The pressure control part is connected to the pressure compensation part and controls the pressure of the pressure compensation part according to the pressure of the combustor. The pressure compensation part comprises a pressure compensation chamber(2) which accommodates nitrogen creating pressure with a specified rate to the internal pressure of the combustor and a second observation window(4) which is formed on one side of the pressure compensation chamber on the same line as the first observation window.
