摘　　要：提出了一种新型空气预热器,该预热器依靠8个阀门的不同开闭来控制空气与烟气交替流过2个蓄热体,从而实现烟气对空气的加热.分析表明,新型空气预热器与回转式空气预热器相比,漏风率大大降低,不到3%.Through the analysis of the existing air pre-heater, one kind of new air pre-heater is proposed. The new air pre-heater controls the air and the flue gas flowing across two regeneration bodies in turn depending upon 8 valves make and break to heat the air. The analysis indicated that the leakage rate of new air pre-heater reduces greatly, lower 30% than the rotation type air pre-heater.
