電蒸汽鍋爐每個排污關上聯表有兩只排污閥，排污時首先二只全開，然后微開第一只排污閥以便預熱排污管道，待管道預熱后再緩緩開大第一只排污閥。排污完畢必須先緩緩關小第一只排污閥，關閉后再關第二只排污閥。那么在排污時應該注意哪些問題呢？

1、電蒸汽鍋爐http://www.akcaya.com/排污時禁止兩臺鍋爐同時排污，如其一臺鍋爐正在檢修，則排污前必須將檢修中的鍋爐與排污管路隔斷分開。
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、電蒸汽鍋爐排污應在低負荷，高水位時進行，在排污時應密切注意鍋爐內的水位，每次排污以降低水位25～50毫米范圍為適宜。
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、電蒸汽鍋爐排污閥門卡住，扳動不靈時，嚴禁用長杠、大錘等工具強力擰動或敲擊，以防損壞閥門，發生危險。
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、電蒸汽鍋爐http://www.akcaya.com/關閉排污閥后，應檢查排污閥是否嚴密，檢查方法是關閉排污閥，過一些時間后,在離開第二只排污閥的管道上用手試摸，是否冷卻，如并不冷卻，則排污閥有滲漏。
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.
