电蒸汽锅炉每个排污关上联表有两只排污阀，排污时首先二只全开，然后微开第一只排污阀以便预热排污管道，待管道预热后再缓缓开大第一只排污阀。排污完毕必须先缓缓关小第一只排污阀，关闭后再关第二只排污阀。那么在排污时应该注意哪些问题呢？
1、电蒸汽锅炉http://www.jnshengxin.cn/排污时禁止两台锅炉同时排污，如其一台锅炉正在检修，则排污前必须将检修中的锅炉与排污管路隔断分开。
Electric steam boiler ban two boilers at the same time when the sewage discharge, as it was a boiler maintenance, maintenance of the boiler must be way off and separate outfall sewage before it.
2、电蒸汽锅炉排污应在低负荷，高水位时进行，在排污时应密切注意锅炉内的水位，每次排污以降低水位25～50毫米范围为适宜。
Electric steam boiler blowdown should be at low load, high water level, pay close attention to the water level in the boiler when the sewage, sewage to reduce the water level every 25 to 50 mm range is appropriate.
3、电蒸汽锅炉排污阀门卡住，扳动不灵时，严禁用长杠、大锤等工具强力拧动或敲击，以防损坏阀门，发生危险。
Electric steam boiler blowdown valve is stuck, when pulled ineffective, non-bars with a long, powerful tools such as sledgehammers twist or strike, to prevent damage to the valve, dangerous.
4、电蒸汽锅炉http://www.jnshengxin.cn/关闭排污阀后，应检查排污阀是否严密，检查方法是关闭排污阀，过一些时间后,在离开第二只排污阀的管道上用手试摸，是否冷却，如并不冷却，则排污阀有渗漏。
After the electric steam boiler blowdown valve closed, check the drain valve is tight, close the drain valve check is, after some time, leaving only the second in the sewage pipe valve hand touch test whether cooling, such as not cool the drain valve leaks.
