A flameholder is made of inner and outer wall members spaced apart for admission of coolant therebetween, the walls having aligned holes for the admission of fuel-air mixture from the space surrounding the flameholder to the space within the flameholder and the walls being held in spaced relation to one another by flanged tubes surrounding the holes in the outer wall and extending inwardly through the aligned holes in the inner wall, the tubes having lateral flanges on the inner ends overlying the inner surface of the inner wall.
