By measuring the air volume of the thermal power unit air-duct,accurate air flow management can be achieved to realize energy conservation. Through the study of the air volume measurement of large cross-section ducts,this paper analyzes the characteristics of large-section air duct air volume measurement,and uses the finite element theory to numerically analyze the airflow field,combining with the practical application of thermal power measurement of thermal power boiler units. Finally,the conclusion is obtained that the thermal gas mass flow meter is suitable for the measurement of the large-section air-duct air flow.
