High Temperature Air Combustion (HTAC) is new-type combustion technology with great energy-saving and environment protection. This technology is to make two regenerators to absorb heat and send out heat alternatively through the reversal valve, recuperate the heat of the exhaust gas to the maximum extent, then heat the combustion-supporting air and coal gas to over 1000° C, even the inferior fuel of lower calorific power can also catch fire steadily and burns high-efficiently. The heat storage honeycomb ceramic as heat exchange media is the key part of HTAC.
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, mining industry and so on. Ceramic Honeycomb is specified as structured regenerative media of RTO/RCO.
Honeycomb ceramic heat accumulation substrate heat capacity can be achieve at more than J/kgk1000. Use a temperature≥ 1700° C in the heating furnace, roaster, soaking furnace, pyrolysis furnace, fuel can be savings of more than 40%, increase in production for more than 15%. The flue gas temperature below 150° C. So It has got a wide application in many industrial productions.
Heat exchanger Honeycomb Ceramic Application:
*NOx purification system in the smoke of the thermal power plant
*The harmful gas purification system in rubbish burning
*Poison gas purification system in chemical and mining industries. The slag filter for casting production in the metallurgical industry. The catalyst substrate stuffing material for chemical industry colums and Contact combustion
Material:
Corundum-mullite, Cordierite-mullite, Cordierite, Mullite, Corundum, Zirconium- mullite etc
Features:
*Low thermal expansion
*High surface area
*Long-term durability performance
*Low pressure drop
*Good thermal shock resistance
*Combined with the EGR systems to help different vehicles to satisfy emission standard
*Low light-off temperature
*Excellent adhesion between wash-coat and susbstrate with netty structure
