The support structure is composed of lintels and gratings. Its main features include: an overall open area of over 58%, capable of handling high gas velocities of 1.5-2m/s, easy fabrication, and low cost. For retrofits, only minor modifications are needed to meet design requirements. Maintenance and replacement of the support structure are very easy. Our company can produce various lintels with Al2O3 content ≤ 75%, width ≥ 40mm, height ≤ 260mm, and length ≤ 2500mm. We can also produce gratings with width and length ≤ 220mm, and height customized to user requirements.
