Abstract

본 발명은 용광로의 버너와 화염상부 공기포트(over fire air port)에 사용되는 회전날개로서, 바닥부와, 날개부재의 저압측면상의 바닥부로부터 수직으로 연장된 연장부가 갖춰진 박판형상의 날개부를 구비하는 바, 상기 연장부는 날개의 저압측면상의 와류의 형성과 전파를 감소시키고, 회전날개를 가로지른 유동효율을 증가시키며 압력손실을 감소시킨다.

Description

버너와 화염상부 공기포트에 사용되는 저와류 회전날개
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 종래 회전날개를 사용한 종래의 뱁콕 앤드 윌콕스 버너의 부분사시도.
제2도는 종래 회전날개의 저압측면의 정면도.

Claims (5)

  1. 바닥부와; 선두선단과, 추미선단 및, 외부선단 및; 날개부재에 고정되고, 이 날개부재의 저압측면상의 날개부재의 바닥부재로부터 대체로 횡방향으로 연장되어, 날개부재의 선두선단으로부터 추미선단으로 유동하는 기체의 흐름내에 상기 날개가 있을 때 날개의 저압측면을 따라 와류의 형성과 전파를 감소시키게 되는 연장부가 구비된 플레이트형상의 회전날개부재.
  2. 제1항에 있어서, 상기 연장부가 날개부재에 대체로 수직하게 연장되는 것을 특징으로 하는 회전날개부재.
  3. 제2항에 있어서, 상기 연장부의 길이가 바닥부의 길이보다 짧으면서, 연장부가 바닥부의 대체로 중심에 놓이는 것을 특징으로 하는 회전날개부재.
  4. 제2항에 있어서, 상기 선두선단과 추미선단들이 서로에 대하여 예각으로 위치되면서, 상기 날개부재의 회부선단이 만곡되고 바닥부가 직선인 것을 특징으로 하는 회전날개부재.
  5. 제1항에 있어서, 상기 연장부가 폭(h)과 길이(l)를 갖고, 이 연장부의 길이에 대한 폭의 비율(h/l)이 0.43내지 0.80의 범위를 갖는 높이대길이(H/L) 비율의 회전날개에 비례하는 것을 특징으로 하는 회전날개부재.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
