空气分配对双旋流燃烧室性能影响的试验研究

In order to investigate the effects of airflow distribution ratio of gas turbine combustor primary zone and dilution zone on combustor performance, an experimental study was conducted on a double swirler annular combustor under actual temperature and pressure condition. The results show that with increment of operation load, combustor outlet temperature distribution factor decreases mostly, radial temperature distribution factor decreases significantly first and then increases slowly and remains stable at last, and total pressure recovery coefficient increases slightly. With increment of airflow ratio of primary zone, outlet temperature distribution factor increases first and then decreases and increases once again, and reaches the minimum value when the airflow ratio of primary zone is 0.343. With increment of airflow ratio of dilution zone, combustor radial temperature distribution factor decreases. Total pressure recovery coefficient keeps stable with change of airflow distribution ratio of primary zone and dilution zone.
