Multi-objective structural optimization of a cyclone for an aggregate drying pulverised coal combustion device
The focus of this work is on the problem of the low efficiency and high pollution caused by the poor quality of coal, unstable loads and other factors in the pulverised coal combustion process. For this reason, a cyclone is installed at the second outlet of pulverised coal combustion devices. Multi-...

| description | The focus of this work is on the problem of the low efficiency and high pollution caused by the poor quality of coal, unstable loads and other factors in the pulverised coal combustion process. For this reason, a cyclone is installed at the second outlet of pulverised coal combustion devices. Multi-parameter and multi-objective optimizations were involved in the design of the cyclone. The influences of the structural parameters on the evaluation index have been rigorously analysed through the evaluation index of the internal flow field of the burner. Further, the genetic algorithm NSGA-II was applied to optimise the structural parameters of the cyclone based on Response Surface Model. The results showed that the outer diameter of the cyclone, the installation angle of the swirl vanes, and the number of swirl vanes had a significant impact on the combustion, as well as the NOX emission characteristics of pulverised coal. When the outer diameter of the cyclone was 500 mm, the number of swirl vanes was 12, and the installation angle of the swirl vanes was 48 degrees, the combustion efficiency of the pulverised coal burner was increased by 47.3%, and the NOX emissions were decreased by 19.1%. |
