Dense Alumina & Dense Cordierite Honeycomb Ceramic
Production
Dense alumina Honeycomb ceramic &Cordierite honeycomb regenerators enhance efficiency, save energy, increase output and improve quality, an important and effective measure when dealing with energy and the environment. They`re applied on thermal equipment for energy saving within industry. The pores of the Honeycomb ceramic regenerators are square and hexagonal, and the channels of pores are straight and parallel to each other. This structure reduces the resistance of passing air and enhances the heat exchange efficiency of every channel.
Characters
- Low water absorption Good acid alkali resistance
- High density good heat storage effect
- large specific surface area
- High heat exchange efficiency
- Lower pressure drop
Functions
- Reduce the thermal loss of exhaust gas, and improve the efficiency of fuel to save energy as.
2 Enhance the burning temperature based on theory, improve the atmospheric burning, meet the high temperature of thermal equipment enlarge low calorific value fuel, especially the application range of blast furnaces, improve the efficiency of calorific value fuel and reduce the emissions from low calorific value coal gas.
3 Improve the terms of heat exchange in hearths, increase the output of equipment, enhance the quality of products and cut down on reinvesting in equipment.
4 Reduce the exhaust emission of thermal equipment, alleviate the air pollution and improve the environment.

2.Honeycomb Ceramic Catalyst Carrier
Product introduction
Honeycomb ceramics as a carrier is the key part of three-way catalytic converters. One of the important materials is cordierite, which can withstand high temperature, the highest continuous working temperature can reach 1200 degrees, high strength, low linear expansion coefficient. The carrier adopts effective surface and appropriate pore structure. The ceramic carrier can have holes of 400-600 mesh/square inch and the minimum wall thickness can be up to about 0.16mm.
Characters
- Low light-off temperature, It can self-sustaining operation when reach a certain concentration without external energy supply and,and save energy.
- The low combustion temperature,flameless combustion,no NOx compounds.
- The fast burning rate, burning completely, no benzo pyrene, dioxin, a highly toxic and carcinogenic substance produced.
- The products of combustion are harmless CO2 and H2O, no solid waste, sewage, waste gas, waste solvent and two pollutants.
- Processing efficiency is very high, the Standard rate in a treatment is far higher than other treatment.
- Process equipment is simple, mature technology, equipment and operation cost is low, the unit cost of waste gas treatment is low.
- Reasonable design, safe and reliable, stable performance, PLC fully automatic operation, no need for special maintenance.
- Extensive application, suitable for high ,low concentration, different industries, all kinds of complex odorous gas treatment.
- Compact structure, small occupation area.
