furnace refractory bricks Cordierite Ceramic Plate honeycomb for infrared catalytic gas burner
It is applied for accumulated and releasing the heat in the regenerative type burner.
Regenerative Thermal/Catalytic Oxidizer (RTO/RCO) are used to destroy Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions etc, which are extensively applied in the fields of Automotive paint, Chemical industry, Electronic & Electric Manufacturing industry, Contact Combustion System, and so on. Ceramic Honeycomb is specified as structured regenerative media of RTO/RCO.
