Product Feature:
Honeycomb ceramic heat storage substrate is the key component of High Temperature Air Combustion Technology (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 >2000 degrees 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 heat 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 reaches 600 degrees, 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.
