下面比較當系統中定速泵（或調速泵）單獨運行、2臺定速泵（或2臺調速泵）并列運行、1臺定速泵與1臺調速泵并列運行的狀況。1定速泵（或調速泵）單獨運行改變泵本身性能曲線的方法有變速調節、動葉調節和汽蝕調節。改變管路特性曲線的方法主要有出口節流調節、入口節流調節，而普遍采用的調節方式是出口端節流調節，它是利用改變閥門開度來進行調節的方式。一般定速泵為出口端節流調節，調速泵為變速調節。鍋爐的啟動時間較長，而且將鍋爐的負荷帶至41t／h的整個提壓過程按機側的要求是逐步達到的，也就是說在這個過程中如果采用調速泵可以僅僅靠改變轉速就能滿足機爐的啟動要求。

它的多項優越性與我國當時經濟能力低下的國情相符合，在我國燃煤電廠得到了極為廣泛的應用。而且，為了保證排放到大氣中SO2擴散稀釋后的濃度合乎大氣環境質量要求，煙囪高度也越來越高，目前，我國煙囪已達24m。我國每年有4多家燃煤電廠利用5多座高煙囪向大氣排放5Mt以上的SO2。由于我國采用高煙囪排放含硫煙氣及分散布點的政策，利用了大氣環境的自凈作用，使得含硫煙氣排放總量在逐年增大的情況下，局部地區大氣SO2濃度基本上仍得到控制。
