先開啟電蒸汽鍋爐http://www.nsfcn.com.cn/慢開閥，后微開電蒸汽鍋爐快開閥，預熱管道后再全開。為使排污效果更佳，可開關快開閥數次。電蒸汽鍋爐排污結束后，先關閉快開閥，再關閉慢開閥，最后再開一下快開閥將兩閥門之間的存水放凈。

1、電蒸汽鍋爐排污前先將爐水調至高于正常水位，排污時要嚴格監視水位，防止因排污造成的鍋爐缺水。排污后間隔一段時間，用手摸排污閥后的排污管道來檢驗是否泄漏，如感覺熱，表明排污閥泄漏，應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、本著“勤排、少排、均勻排”的原則，每班至少排污一次，對電蒸汽鍋爐http://www.nsfcn.com.cn/所有的排污管須輪流進行排污，防止爐水品質惡化和排污管堵塞，甚至引起水循環破壞和爆管。
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.
