AI Technical Summary
Existing rotary air preheaters for boilers are prone to ash blockage under low load, leading to increased resistance and large differential pressure fluctuations, which affects the safe and stable operation of the unit.
A novel heat exchange plate assembly for heat storage elements is designed, employing a structure with several crest and trough sections and oblique sections. When adjacent heat exchange plates are stacked vertically, the crest and trough sections abut each other, and the oblique sections are sealed on both sides. Airflow or water flow is injected between the two crest and trough sections, increasing turbulence and facilitating cleaning.
It improves the cleaning effect of heat exchange plates, reduces manufacturing costs, shortens the production cycle, maintains the original heat exchange efficiency, is not easy to dissipate, and enhances the ability to resist ash blockage.
