The rotary regenerative air preheaterdeveloped by our company has high waste heat utilization efficiency, and thetemperature difference between hot flue gas and hot air is 10-20 ℃; Adopting acombination of brush sealing technology and gas sealing replacement technology,the system has less air leakage and oxygen content changes less than 0.55%during operation; Using honeycomb ceramic thermal storage to completely solvethe problem of low-temperature dew point corrosion; The exhaust temperature canbe flexibly adjusted according to needs, and the discharge temperature of coldflue gas can be as low as 80 "℃; Adopting a flat support structure, therotating body operates smoothly and has low energy consumption duringoperation; Easy to operate, with a service life of over 10 years; In addition,the exhaust temperature is low, and the condensate generated during thecondensation process of the flue gas comes into contact with the flue gas,absorbing NOx, SOx gases and smoke dust in the flue gas, which can reduce theemission of harmful gases; Dust is not easy to adhere under the alternatingblowing and sweeping of smoke and air, and is also easy to fall off under thealternating action of temperature, with self-cleaning function; Equippedwithonline steam blowing or offline water flushing for cleaning, easymaintenance. The rotary regenerative air preheater can save fuel consumption,achieve energy conservation, emission reduction, and efficiency enhancement.
