AI Technical Summary
The existing boiler sampling devices for coal-fired power units are poorly designed, resulting in fly ash sampling data that lacks representativeness and accuracy, affecting boiler efficiency calculations. Furthermore, the devices are complex to install and difficult to maintain, making it difficult to adapt to sampling needs under different operating conditions.
A sampling device comprising a moving component, a transmission component, a collection port, a support frame, and a filter structure was designed. The moving component enables flexible adjustment of the sampling point, the transmission component precisely aligns with the sampling area, the support frame stabilizes the collection component, and the filter structure separates fly ash from flue gas, simplifying installation and maintenance.
It enables multi-point sampling, improves sample representativeness, ensures sampling accuracy, simplifies operation procedures, reduces device complexity, and improves sampling efficiency and data accuracy.
