1 Measurement and Control Devices for Combustion Optimization Sensors and Systems for Combustion Engineering

2 LAMTEC CO-Control A adaptive Burner-Control

3 Adaptive control (fuel/air ratio) Inverter Output (%) Burner load (%) 10% 30% 50% 70% 90% 100% 1 st Step CO = PPM 0 3 rd Step 2 nd Step 10 CO monitoring on combustion air at 50% load O 2 = % Set point curve Correction range

4 Adaptive control (fuel/air ratio) Burner load (%) st Step CO = PPM 0 3 rd Step 2 nd Step CO monitoring on combustion air at 70% load O 2 = % Set point curve Correction range Inverter Output (%)

5 Adaptive control (fuel/air ratio) Burner load (%) st Step CO = PPM 0 3 rd Step 2 nd Step CO monitoring on combustion air at 90% load O 2 = % Correction range Set point curve Inverter Output (%)

6 Burner load (%) Correction range Final curve after CO control at more load points 50% Load 90% Load O2= 1.1% O2= 1.0%O2= 0.9% CO = 0 PPM 70% Load Inverter Output (%)
