he flow of air and flue gas significantly impacts the efficiency,and is thus a crucial factor which directly affects the performance of coal-fired boilers.This paper explores the primary factors that contribute to flow measurement based on theoretical computing and tests,as well as characteristics of mass flow in short pipes of wind-smoke system in coal-fired power plants.It also proposes a combined method of comparative measurement and regional computation to compute the flow of wind smoke.The application and tests show that the optimized method is highly efficient in measuring gas flow. Also,the flow measurement device can be used to estimate the distribution of wind-smoke system flow field.
