Ceramic heat exchanger is actually a new tube-type high temperature and heat recovery unit, its main ingredients is silicon carbide, and ceramic heat exchanger can be far and widely employed in metallurgy, machinery, construction materials, chemical industries, and it can directly recover various 850 to 1400?? gas and heat emitted by the industrial kilns in order to get the high-temperature combusted air or the processed gases.
The heat exchanger components which are produced into ceramic heat exchanger is really a new kind of silicon carbide engineering ceramics, it has exceptional high temperature properties and anti-thermal and shock properties, it won't appear any cracks for repeating 50 times from 1000?? cooling air to room temperature; Its thermal conductivity is equivalent to that of stainless steel; it has excellent corrosion resistance in oxidative and acidic medium. As a result, it with success solves the thermal compensation problem and it can be greater solved the gas sealing problems from the structural perspective. Ceramic heat exchanger's heat transfer efficiency is high, so its energy conservation effect is remarkable, so it could be utilized for preheating combustion air or the processed gas heating the some process, it even can save one-time energy and also the fuel savings are up to 30% -55%, and it can boost the method, which would substantially enhance production capacity.
Ceramic heat exchanger's production method is fundamentally the same as that of the kiln, its thermal conductivity and oxidation resistance properties are the material's principal application. Its principle is to place the ceramic heat exchanger close to the flue outlet where the temperature is pretty high, so it'll not mixed with cold wind and it will not require the high temperature protection, when the furnace temperature is 1250 to 1450??, the flue gas outlet's temperature should really be 1000 to 1300??, the waste heat's temperature recovered by ceramic heat exchanger can be reached 450-750??, sending the recycled hot air to the furnace and forming the mixed gas with the combustion gas, and then it can be burned, in performing so, it can directly decrease production costs and increase economic efficiency.
Under the limited use of the metal heat exchanger, ceramic heat exchanger has gotten particularly great development, for it greater solves the corrosion resistance, high temperature and also of topics. Its principal good points are: very good thermal conductivity, high strength in high temperature, oxidation resistance, excellent thermal shock resistance, lengthy service life, modest number of maintenance, reliable and stable properties too as straightforward operation. |
