      Model predictive control for improving waste heat recovery

      After receiving heat and attaining a high temperature of ∼980 °C, the circulation gas leaves the tower and heads to the boiler. The hot circulation gas then transfers its heat energy to the feed-water in the boiler and is cooled. Subsequently, the circulation gas passes through a sub-economizer and returns to the tower for the next cycle.
