Understanding Electrostatic Precipitator Operation 24 Hour Emergency Heating Service Ac Repair Company Near Me Heating And Ac Service Near Me

Before diving into specific fixes, it’s essential to understand the fundamental principles of ESP operation. ESPs work by charging particles in the flue gas stream and then using an electric field to collect these charged particles on collection plates. The process typically involves the following stages: Phoenix Air Conditioning Repair Air Conditioning Repair Companies Near Me Air Conditioning And Heating Services Near Me

1. Ionization: High-voltage electrodes, known as discharge electrodes, create a corona discharge, which ionizes the gas molecules surrounding the electrodes. These ions then collide with the particulate matter, imparting a negative charge to the particles. 24 Hvac Service Near Me Near Ac Service Heating Ac Service Near Me

2. Collection: The negatively charged particles are drawn to positively charged collection plates (also known as collecting electrodes) due to the electrostatic force. 24 Hour Emergency Air Conditioning Service Near Me Hvac Service Companies Near Me Home Heating Repair Service Near Me

3. Rapping: Over time, the collected particles form a layer on the collection plates. To remove this layer, rapping systems are used to periodically strike the plates, causing the particles to dislodge and fall into hoppers below.
