Description
Product Description
Ceramic honeycomb could enhance efficiency, say energy , increase output and improve quality, as important and effective measure of dealing with energy and environment. They are applied on thermal equipment of energy saving in industry widely. The shapes of pores of ceramic honeycomb are square and hexagon, and the channels of pores are straight and parallel each other. This structure reduces the resistance of passing air and enhances the heat exchange efficiency of every channel.
The Advantage:
1.Good heat resistance, good thermal conductivity and high mechanical strength.
2.The wall of the hole is thin, the wall of the hole is smooth, the back pressure is small, the capacity is great, the heat storage is large and the volume of space is small.
3.When the product has high regularity, the heat storage body is neatly discharged and the dislocation is small.
The Application :
It is the key component of the regenerative burner, which is widely used in the regenerator, heat exchanger and other equipment in the chemical, metallurgical and environmental protection industries.Regular honeycomb ceramic fillers designed for regenerative heat oxidizer and regenerative heat exchanger for organic waste gas treatment equipment.
