Main Methods:

• Testing ESPs with varying electrode configurations across a temperature range of 450-900 K.
• Analyzing electric field, flow field, and particle capture characteristics.
• Comparing different ESP models to identify optimal designs.

Main Results:

• Increased temperature leads to decreased operating voltage and air density.
• Higher temperatures reduce electric field strength and space charge density, impairing particle collection.
• Collection efficiency diminishes with rising temperatures, with a notable impact on larger particles.
• ESP electrode configuration significantly affects particle migration velocity and overall efficiency.

Conclusions:

• Temperature is a critical factor influencing electrostatic dust collector efficiency.
• Optimizing electrode design, such as in the B model, can enhance performance under varying temperatures.
