Cordierite/Mullite/Alumina Ceramic Honeycomb Filter for Heater
Product Description
Ceramic honeycomb heater 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.
Honeycomb ceramic heater is composed of countless equal holes. The structure of it is like honeycomb shape and it is a kind of new ceramic products. The biggest hole number of it has reached 20~40 per square centimeter, the density is 4~6 grams per cubic centimeter and the water absorption rate is above 20%.
Material:
Corundum-mullite, Cordierite-mullite, Cordierite, Mullite, Corundum, Zirconium-mullite etc
Application:
Ceramic honeycomb heater is widely used in chemical industry, electric power industry, metallurgy industry, petroleum industry, electronics industry, machinery industry, etc.
Features:
*High strength
*High temperature resistance
*Corrosion resistance
*Wear resistance
*Good thermal conductivity
*Environmentally friendly
