先开启电蒸汽锅炉http://www.jnshengxin.cn/慢开阀，后微开电蒸汽锅炉快开阀，预热管道后再全开。为使排污效果更佳，可开关快开阀数次。电蒸汽锅炉排污结束后，先关闭快开阀，再关闭慢开阀，最后再开一下快开阀将两阀门之间的存水放净。
1、电蒸汽锅炉排污前先将炉水调至高于正常水位，排污时要严格监视水位，防止因排污造成的锅炉缺水。排污后间隔一段时间，用手摸排污阀后的排污管道来检验是否泄漏，如感觉热，表明排污阀泄漏，应查明原因后加以消除。
Electric furnace before the first steam boiler blowdown water is adjusted higher than the normal level, when sewage to strictly monitor the water level to prevent water pollution caused by the boiler. After the intervals between sewage, sewage pipes by hand after touching the drain valve to test for leaks, such as feeling hot, indicating the drain valve leaks, be eliminated after the reasons should be identified.
2、本着“勤排、少排、均匀排”的原则，每班至少排污一次，对电蒸汽锅炉http://www.jnshengxin.cn/所有的排污管须轮流进行排污，防止炉水品质恶化和排污管堵塞，甚至引起水循环破坏和爆管。
In the "ground row, row less uniform discharge" principle, each class at least once sewage, electrical steam boilers must turn all the sewage outfall, water quality deterioration and prevent furnace clogged sewage pipes, and even cause damage and burst water cycle tube.
