High Temperature Air Combustion Technology(HTAC) have dual effects on energy saving and environment protection. Comparing with the conventional combustion technology, HTC will save approximately 20-50% fuels, decrease the oxidation and lgnition loss by 20%,reduce NOx emissions by 40% and bring up the production output £¾ 20%.As a key component of HTAC , honeycomb heat storage substrates have the following features: large unit heat transfer surface, high heat conductivity, low pressure drop, low heat penetration depth and high thermal efficiency. Moreover, channel shapes are available in: square channel, round channel and hexagonal channel. Face shapes are also available in: plane face, inclined face, single groove channel face, double groove channel face. The technicians from our company innovatively manufacture the honeycomb heat storage substrate, baffle brick and ball by synthesizing chromium corundum and high purity mullite using £¾2000 ¡æ high temperature electro-cast. We are the first company apply this manufacturing method in China . The synthetic material have the following features: high temperature resistance, high softening point, excellent de-slagging ability, outstanding thermal stability, fast haet conductivity, high density and high heat capacity . By applying the new synthetic material, our products dramatically lower down the plugging, fusing, slagging, cracking, powdering and spalling phenomenon. The service life of our products is equivalent to international famous brand. Furthermore ,when the temperature reach 600 ¡æ, the catalyst on the substrates can boost a catalytic combustion on the compound of CO, HC from the smoke. This method is wide spreading to increase the surplus heat recovery and minimize the waste gas emissions.
