| Abstract: | To avoid the plugging of primary measurement element is a key problem to the realization of flow velocity on-line monitoring of pulverized coal borne air of utility boiler. This paper introduces one kind of primary measurement element and measurement system which can effectively prevent the pressure transmission tube from being plugged by solid particles in the airflow through the full and accurate test data. The study and application results show that, to adopt counter blowing type back-supported tube as the primary element of measurement system of pulverized coal borne air flow, has not only solved the plugging problems of pressure transmission tube very well, but also the measurement accuracy of system is very high. |
