蒸汽鍋爐使用過(guò)程中要經(jīng)常排污，排污可大大增加鍋爐的使用壽命，下面就與大家分享一下蒸汽鍋爐排污的要求。
排污分為連續(xù)排污和定期排污。連續(xù)排污是連續(xù)不斷地從鍋爐水表面，將濃度較高的鍋爐水排出。它是降低鍋爐水中的含鹽量和堿度，以及排除鍋爐水表面的油脂和泡沫的重要方式。定期排污時(shí)在鍋爐系統(tǒng)的最低點(diǎn)間斷地進(jìn)行。它是排出鍋爐內(nèi)形成的泥垢以及其他沉淀物的有效方式。另外，定期排污還能迅速地調(diào)節(jié)鍋爐水濃度，以補(bǔ)連續(xù)排污的不足。鍋爐排污的質(zhì)量，不但取決于排污量的多少，以及排污的方式，而且只有按照排污的要求方法進(jìn)行，才能保證排出水量，排污效果好。
1、勤排。排污的次數(shù)要多一些，特別用底部排污來(lái)排除污泥時(shí)，短時(shí)間的，多次的排污，要比長(zhǎng)時(shí)間的，一次排污及排泥效果要好的多。
The number of sewage to be more, especially when used to exclude sewage sludge at the bottom, short-term, repeated sewage, than the long, once the sewage and sludge achieve much more.
2、少排。只要做到勤排，必然會(huì)做到少排，即每次排污量要少，這樣既可以保證不影響供氣，又會(huì)使鍋爐水質(zhì)量始終控制在標(biāo)準(zhǔn)范圍內(nèi)，而不會(huì)產(chǎn)生極大地波動(dòng)，這對(duì)鍋爐保養(yǎng)十分有利。
As long as the ground row is bound to be less row, that is, each less emissions, both to ensure that does not affect the supply, but also make the boiler water quality is always controlled within the standard range, but does not produce greatly fluctuating this is very beneficial for boiler maintenance.
3、均衡排。要使每次排污的時(shí)間間隔大體相同，使鍋爐水質(zhì)量經(jīng)常保持在均衡狀態(tài)下。
For much the same each time interval of sewage, the boiler water quality regularly maintained at equilibrium.
4、在鍋爐低負(fù)荷下排污。此時(shí)因?yàn)樗h(huán)速度低，水渣容易下沉，定期排除效果好。
Under low load boiler emissions. At this point because of the low water circulation rate, slag easily sink regularly exclude the effect is good.
