    取暖锅炉在供暖前对蒸汽管道的预热 , 称为 ''暖管'' 。暖管的目的是使蒸汽管道及其阀门、法兰等缓慢地加热升温 , 使管 道温度逐渐接近蒸汽温度 , 为供汽做好准备。
    The preheating of a steam pipe before heating is called a 'heating pipe'. The purpose of the heating pipe is to slowly heat up the steam pipe and its valves and flanges so that the pipe temperature is gradually approaching the steam temperature and ready for the steam supply.
    如不预先暖管 就直接送汽 , 会使管道、阀门、法兰等部件因升温不均匀而 产生热应力受损。
    If not in advance, the heating pipe will be sent directly to the steam, will make pipes, valves, flanges and other components due to uneven heating and thermal stress damage.
    另外 , 未暖管就送汽 , 管内蒸汽突然遇冷 凝结 , 会形成局部低压 , 使蒸汽挟带冷凝水向低压处冲击 , 发 生 水锤现象水锤 可使管道变形、震坏,保温层损坏 , 严重时能管道震裂。
    In addition, did not send steam heating pipe, inner pipe steam condenses when suddenly, will form a local low pressure, the steam condensed water with impact to low pressure, water hammer water hammer phenomenon can cause the pipeline deformation, shock, insulation damage, serious when can shatter pipeline.
    因此送汽前必须进行暖管。暖管前 , 先开启主蒸汽管道上的所有疏水阀排出蒸汽管 道内积存的冷凝水 , 然后缓慢开启锅炉主汽阀约半圈 ( 或缓慢开启旁通阀 ), 让少量的蒸汽进入管道 , 使其温度逐渐升高 , 待管道充分预热后 , 再将锅炉的主汽阀全开启。
    Therefore, the steam pipe must be heated before delivery. Before the first open the heating pipe, all drain valves of the main steam pipe to discharge condensed water accumulated inside the steam pipe, and then slowly open the boiler main steam valve about half circle (or slowly open bypass valve), a small amount of steam into the pipe, the temperature gradually increased to pipe full preheating, the main steam the full open valve of boiler.
