4. Conclusions The stresses induced in the concrete due to thermal gradients and self-weight must be lowered. Therefore, the solution found for the cyclone involves: • reinforcing the external framework and its connection to the cyclone's roof; • taking advantage of the internal steel framework, develop a new brick support layout that replaces the concrete (Fig. 8); the insertion and removal of the bricks should be done quickly where the bricks get damaged. This should confirm the better heat and wear resistance of the cyclone, avoiding the concrete failure.
