Honeycomb Ceramic Regenerator

 

 

High Temperature Air Combustion (HTAC) is new-type combustion technology with great energy-saving and environment protection. This technology is to make two regenerator 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.

 

Product Features

● Reduce the thermal loss of exhaust gas, and improve the efficiency

● Enhance the theory burning temperature, improve the atmospheric burning, meet the high temperature of thermal equipment, enlarge the application of low calorific value, especially the application range of blast furnaces, improve the efficiency of calorific value and reduce the emissions from low calorific value coal gas.

● Improve the terms of heat exchange in hearths, increase the output of equipment, enhance the quality of products and cut down on reinvesing in equipment/

● Reduce the exhaust emission of thermal equipment, alleviate the air pollution and improve the environment.

 

Product Characteristics

●  High temperature resistance, corrosion resistance, good thermal shock resistance, high strength, large heat storage capacity, good thermal conductivity, etc. and the energy saving effect and the service life are greatly improved.

 

Product Application

● Widely used in all kinds of heating furnace, hot blast furnace, heat treatment furnace, cracking furnace, baking equipment, melting furnace, soaking furnace, oil and gas boiler furnace in iron and steel industry, building materials industry, chemical industry, petrochemical industry, paint industry, non-ferrous metal smelting industry.
