Brief introduction of honeycomb ceramic regenerator
The sectional face of honeycomb ceramic regenerator mainly has two kinds of hole structure, square and regular hexagon, and the holes are parallel to each other. This structure greatly reduces the resistance of pore flow and greatly improves the single pore volume heat transfer efficiency of heat accumulator.
Features of honeycomb ceramic regenerator
Honeycomb ceramic regenerator has the characteristics of low thermal expansion, large specific heat capacity, large specific surface area, small pressure drop, small thermal resistance, good thermal conductivity, good heat shock and so on.
Application of honeycomb ceramic regenerator
Honeycomb ceramic regenerator is mainly used in steel works, waste incinerators, waste gas treatment thermal equipment, chemical plants, smelters, power plants, power industry boilers, gas turbines, engineering heating equipment, ethylene cracking furnace, etc.
Advantages of honeycomb ceramic regenerator
- Various materials, according to the different customers and use environment, choose different materials and specifications of products.
- Thin hole wall, large capacity, large heat storage, small space occupation.
- Smooth wall and small back pressure.
- Long service life, not easy to slag erosion, adhesion and high temperature deformation.
- The product has high quality and specifications. During installation, the discharge between the heat accumulator is neat and the dislocation is small.
- Good heat resistant impact, good thermal conductivity, high mechanical strength.
