Invensys Operations Management implemented a combustion optimization control system for two coal-fired 600MW power boiler units operated by the China Huadian Inner Mongolia Energy Co., Ltd Baotou Power Generation Branch.

The advanced process control (APC) project passed technical and acceptance testing administered by the Xi’an Thermal Power Research Institute and helped save energy costs, reduce emissions, more than double the ramp up rate and improve boiler performance efficiency for electric power plant units #1 and #2 in Baotou, Inner Mongolia.

The China Huadian Inner Mongolia Energy Co., Ltd Baotou Power Generation Branch, generates 7 billion kilowatt hours of power per year and serves more than 8 million square meters.

The Invensys team optimized boiler performance and combustion efficiency by implementing its SimSci-Esscor CONNOISSEUR multi-variable predictive control (MPC) software and non-linearity and neural networking technology across the plants’ distributed control systems (DCS). The DCSs receive input from the MPC software to manage closed-loop optimization control over the boiler and steam turbine operations, increasing boiler combustion and overall operating efficiency. The Invensys solution helped lower coal consumption, reduce carbon and NOx emissions in fly ash, improve unit safety and operating stability, promote rapid response to load adjustment commands and reduce equipment failure and unplanned downtime.

“(Users) continue to face increasing operating costs and are always under great pressure to extract maximum value from their assets,” said Ravi Gopinath, president, Invensys Operations Management, Asia Pacific.
