摘　　要：高压燃气在调压过程中,通常需要经过多次减压才能达到用户使用压力。由于焦耳-汤姆逊效应,所以燃气在绝热节流膨胀的过程中会产生温降现象。为避免温度过低对不同设备、管道、材料性能的影响,需要合理选用不同供热设备,以满足不同燃烧器对燃气的温度要求。During the pressure regulation process of high pressure gas,it usually requires depressurization to reach the user's operating pressure.Due to the Joule-Thomson effect,gas will experience a temperature drop during adiabatic throttling expansion.To avoid the impact of low temperature on the performance of different equipment,pipelines and materials,it is necessary to choose different heating equipment reasonably to meet the gas temperature requirements of different burners.
