CombustionOpt is the leading real-time combustion optimization solution in the power industry. CombustionOpt provides closed-loop optimization of fuel and air mixing by manipulating relevant fuel and air injection points to reduce NOx and other emissions and improve fuel efficiency. It extracts knowledge about the combustion process, determines the optimal balance of fuel and air flows in the furnace, and responds to changing conditions. CombustionOpt adjusts the DCS or other control system biases to more consistently position dampers, burner tilts, overfire air and other controllable parameters at their optimal settings for given sets of conditions, objectives and constraints. It has helped more than 200 generating units achieve reduced NOx emissions, improved boiler efficiency, better controlled CO, LOI, and opacity, and more consistent combustion and boiler operations.
The latest version of CombustionOpt combines neural network and model predictive control (MPC) technologies to provide even better results. It also provides deep insight into why cloised-loop combustion optimization actions are being taken, advanced analysis tools, and real-time benefits benchmarking. The addition of expert system-based heuristic rules also enables CombustionOpt to alert users to boiler conditions of interest and provide advice for how to further extend the combustion optimization benefits.
