Thesis title: "Study on the influence of some main parameters on the durability of the discharge electrode frame of electrostatic precipitators"

Summary of new conclusions of the thesis

1. Scientific significance:

- Through experiments on a static model and a practical model of the filter chamber of a horizontal electrostatic precipitator (ESP), three parameters were optimized: hammer mass (m), drop height (h), and inlet dust concentration (η) meeting the rapping acceleration (a) of the discharge electrode frame and the impact force (F) of the hammer;

- Through experiments on a discharge electrode model using fatigue testing of scaled specimens, an experimental fatigue curve was constructed according to the theory of B. P. Kogaiev regarding the relationship between fatigue strength (σ_m) and fatigue life in cycles (N).

2. Practical significance

- The research results can be applied to design the discharge electrode frame set for the filter chamber of a horizontal ESP with force distribution on the discharge frame at different loading positions and for ESPs of different capacities.

- The research results can also be used as reference material in teaching and research.

3. New contributions of the thesis

- Through experiments on a static model combined with a practical model of the filter chamber with the same capacity of the horizontal ESP, three parameters were optimized: hammer mass (m), drop height (h), and inlet dust concentration (η) meeting the output criteria, namely the rapping acceleration (a) and the hammer striking force (F), respectively;

- Through experiments on a static model and a practical model with the same capacity of the dust filter chamber, an experimental fatigue curve was constructed according to the theory of the relationship between fatigue strength (σ_m) and fatigue life (N) of the discharge electrode frame.
