furnace refractory bricks honeycomb ceramic heat accumulation
converter
It is applied for accumulated and releasing the heat in the
regenerative type burner.
Honeycomb Ceramic
Honeycomb ceramics are a new kind of industrial ceramic product developed in recent
years. They have a large surface area, higher air vent rate, good
heat functions, stable chemical properties etc.
At present, ceramic honeycombs are being used to purify industrial
waste gas, automobile emissions, eliminate noise, deal with waste
water, to dry air, incineration, used in the manufacture of
infrared ray instruments, to filter metal liquids etc.
All ceramic honeycombs can be produced in conformance with customer
requests.
