PHASE ONE PHASE TWO
PHASE THREE
COMBUSTION EFFICIENCY
Controlling this important process reaction reduces emissions of key pollutants , including NOx , SOx , carbon monoxide ( CO ) and carbon dioxide ( CO 2 ), lowers fuel consumption , and improves safety . Accurate measurements of oxygen ( O 2 ) and combustibles ( COe ) in the reaction mixture allow the optimum ratio between fuel and air to be achieved .
GAS CLEANING
This involves the safe removal of harmful substances from process gases that might otherwise be emitted by the plant . Typical applications within this phase include DeNOx treatments ( i . e . ammonia slip processes ) and flue gas desulfurization . A variety of gas measurements are required depending on the gas cleaning process being used .
EMISSIONS MONITORING
Measuring pollutants within the flue gas helps to determine process efficiency , protect the environment , and demonstrates that plant operators are compliant with regulations . Continuous monitoring is required to measure all the necessary components of the flue gas , including criterion pollutants and greenhouse gases .
