摘要：
The grid for the parallel rows of tubes is composed of metal guide strips and spacer strips. The guide strips are disposed in pairs with semi-cylindrical portions defining circular openings for the tubes. The spacer strips are formed with bent portions to bear against the semi-cylindrical portions of the guide strips as well as rectilinear portions which are radial to the tubes.
