Combustion control ASCOMB Series ENERGY SAVING Starting from combustion theory… In figure 1, it is possible to identify the optimal combustion zone where the high efficiency matches the minimum pollution values thanks to the correct air/flue ratio. Modifying the boiler load, the air/fuel ratio is changed dynamically as shown in fig.2 Through the continuous oxygen content monitoring in the flue gases and boiler load, it is possible to keep the burner in the optimal combustion zone to ensure better performance and lower pollution levels. of comb ustion Unburnst losses Smoke increase Fig. 1 - Characteristics...

Combustion Control Ascomb series LAws ANd reGuLAtioNs Various pollution control standards have been developed over the years. the environmental conservation directives regulate the flue gas emissions that civil and industrial plants generate into the atmosphere. the flue gas oxygen content has always been an important reference parameter. this is the main measurement of AsComb systems for combustion monitoring and control. in addition, the systems may measure and record other combustion parameters such as carbon monoxide and flue gases temperature. therefore, the AsComb systems may be useful...
