Porous Ceramic Disc For Combustor Gas Filter

Porous Ceramic Disc For Combustor Gas Filter

Porous ceramic discs are often used in combustor gas filters to remove impurities and particulate matter from gas streams in various industrial applications. These discs are designed to allow the passage of clean gases while trapping and removing contaminants. Here’s an overview of how porous ceramic discs work in combustor gas filters:

1. Filtration Mechanism: Porous ceramic discs operate based on a physical filtration mechanism. The discs are made from ceramic materials with controlled porosity. This porosity is characterized by a network of interconnected pores of a specific size and distribution.

2. Gas Flow: The contaminated gas flows through the porous ceramic discs. The pores in the ceramic material act as a barrier, allowing only clean gas to pass through while blocking larger particles, dust, soot, and other contaminants.

3. Particle Capture: As the gas passes through the porous ceramic material, particles and impurities in the gas stream are captured on the surface and within the pores of the ceramic disc. The porous structure provides a high surface area for effective particle capture.

4. Pressure Drop: Filtration using porous ceramic discs can lead to a pressure drop across the filter. The extent of the pressure drop depends on factors such as the porosity, thickness, and permeability of the ceramic disc, as well as the flow rate of the gas.

5. Maintenance and Cleaning: Over time, the captured particles accumulate on the surface and within the pores of the ceramic disc, reducing the filter’s efficiency and increasing the pressure drop. Periodic maintenance is required to clean or replace the ceramic discs to ensure proper filtration.
