摘　　要：报道了研制的EJT型可调脱碳喷射器的特点是气量大、所需工作压力小、喷嘴可调节、工作稳定、效率高。该设备采用不锈钢精密加工制成 ,在河南安阳等 12座中型合成氨装置进行了工业试验 ,表明采用新型可调脱碳喷射器及相应新工艺 ,CO2 脱碳再生热耗可以降低到 312 0～ 3344kJ/m3 ,平均节能 4 0 %以上。Adjustable decarbonization ejector of sub-sound speed is the key facility of transformation regeneration technique for low supply heat. The characteristic of this ejector is that, the gas rate is high, the working pressure is low, the nozzle is adjustable, with stable running. It is made of stainless steel, and has been used in twelve chemical fertilizer factory of mediam size. The heat energy supply is 3120kJ/m 3 CO 2 by wsing this new technique. More than 40% energy would be saved comparing with tradi1tion technique.
