In recent years the development of ceramic honeycomb regenerative heat exchange device is one of the key components of HTAC technology.The device has big storage quantity of heat, heat transfer speed, good structural strength, high temperature and high pressure resistance, resistance to oxidation and corrosion, small resistance loss, economic and durable, etc.Its material ingredient for alumina.Because of its porous structure, so the heat exchange volume very high specific surface area.Cellular channel in a straight line, the pressure loss is small, not easy to dust jam, because of the regenerator high-speed heat storage and heat release, the switch time can be set for 20-30 seconds.Using this device, above 1000 ℃ high temperature flue gas can be reduced to below 200 ℃ and normal temperature air preheat temperature close to the high temperature flue gas (typically differ only 50 ~ 150 ℃).The device's thermal efficiency can reach above 80%.Due to this type of regenerator has the very high heat transfer surface, regenerator requirements significantly reduced, so that after adding regenerator not much effect on the volume of radiant tube.
