Honeycomb Heat Exchanger Substrate Honeycomb Ceramic Monolith

Product Description

Honeycomb Heat Exchanger Substrate Honeycomb Ceramic Monolith
Description:
High Temperature Air Combustion (HTAC) 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 1000ºC, 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.

Advantage:
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.
