Advancements in Combustion Control Algorithms for Regenerative Systems (Room 317)

The frequent cycling of a regenerative system places many challenges on a combustion controls system; maintaining furnace pressure and balancing flows to each burner in the pair are difficult. An innovative controls approach has shown promise in addressing these concerns. Combining the cycle and flow control valves, monitoring the flows through each bed, and eliminating some continuous control loops in favor of step-wise changes allow for more robust and consistent control of the system. These advancements in combustion control algorithms are promising, showing savings in both fuel and electricity costs (and thus reducing emissions). While savings are most dramatic on batch cycles where extreme turndown is common, these controls concepts are applicable to continuous processes as well.
