Research on condensation heat transfer with presence of non - condensable gases 具有不凝结气体存在的凝结换热研究
2.
Open the air - release valve of the trap beforework to discharge a large quantity of non - frozen gas . then drivetightly the air - release valve and preheat gradually . the preheatrate should not be more than 36 / minutes 疏水阀在工作前需打开放气阀,使不凝结气体大量排出,然后拧紧放气阀,并逐渐预热,预热率不超过36 / 8分钟。
