Honeycomb Ceramic for RTO, RCO

Introduction
Honeycomb ceramic for RTO, RCO, as heat exchange media, adopts HTAC (High Temperature Air Combustion) technology. It has been widely applied in all kinds of pushing-steel heating furnace, RTO (Regenerative Thermal Oxidizer), RCO(Regenerative Catalytic Oxidizer), stepping heating furnaces, heat treatment furnaces, forging furnaces and dissolving furnaces. This ceramic honeycomb is also used for steel wrapping or middle wrapping baking apparatus, soaking pits, radiation tap incendiary apparatus, covering furnace, high temperature hot-blast stove in metallurgical machine buildings and all kinds of ceramic cellar stoves, glass cellar stoves, tap heating stoves, splitting stove and other industrial cellar stoves.

Advantages
Honeycomb ceramic for RTO, RCO, as heat storage body, enjoys the advantages of large specific surface area, small heat resistance, good thermal conductivity and excellent thermal shock resistance. This ceramic honeycomb also realizes quick exchanging heat and saves energy in the strict sense (Up to 97% of true thermal energy can be recovered and it can also absorb more than 40% NOx).
