2 Optimization of air ratio
3 The air ratio is calculated from the O2 content (O2%) in the exhaust gas.
4 Larger air ratio leads to larger heat loss with the exhaust gas.
5 Fuel saving by air ratio improvement
6 Effect of air ratio reduction
7 Criteria for air ratio (standard values)
8 Criteria for air ratio (target value)
9 Energy conservation by air preheating
10 Utilization of waste heat of exhaust gas - air preheating
11 Criteria for exhaust gas temperature
12 Criteria for factories
