Product Details
Honeycomb ceramics regenerator is the key part of high temperature air combustion (HTAC). It has the following notable characters: Perfect high-temperature resistance, anticorrosion, perfect thermal shock stability, high mechanical strength, large thermal storage capacity, advantaging heat- conduction property, energy- Conserving result and service life are improved greatly. It is extensively used in many kinds of heater, sirocco furnace, heat treatment furnace, cracking column, roaster, melting furnace, balance heating stove and etc. The results show that the honeycomb ceramics regenerator has high heat transfer efficiency, which can reach 87.02% at the temperature of 1130º C, and the combustion temperature is stable at the moment of switching. Mainly materials are cordierite, mullite, alumina and corundum.
