除碳器水位控制系統(tǒng)主要調(diào)節(jié)除碳器液位，通過調(diào)節(jié)陽床入口調(diào)節(jié)門來實(shí)現(xiàn)。其特征在于當(dāng)除碳器液位高于設(shè)定的高值時(shí)，液位傳感器傳遞信號(hào)使控制器控制陽床入口調(diào)節(jié)閥的開度變?。划?dāng)除碳器液位小于設(shè)定的低值時(shí)，液位傳感器傳遞信號(hào)使控制器控制陽床入口調(diào)節(jié)閥的開度變大。由于流經(jīng)陽床入口調(diào)節(jié)閥的工質(zhì)要先經(jīng)過陽床才能到達(dá)除碳器，工藝流程較長（見圖2），所以回路調(diào)節(jié)時(shí)要加入慣性作用。

創(chuàng)元電廠水網(wǎng)改造完成后，自動(dòng)化控制水平明顯提高，完全保證了兩臺(tái)發(fā)電機(jī)組的用水需要。同時(shí)改造后，水網(wǎng)制水過程中產(chǎn)生的廢水量明顯減少，起到了一定的節(jié)能環(huán)保效果。系統(tǒng)高度的可靠性和直觀簡易的操作性大大節(jié)約了人力成本。該系統(tǒng)建成后運(yùn)行可靠，生產(chǎn)效率明顯提高，也為其它電廠同行實(shí)現(xiàn)DCS管控一體化提供了寶貴的運(yùn)行經(jīng)驗(yàn)?？傊?，隨著自控技術(shù)的不斷發(fā)展和電廠水網(wǎng)運(yùn)行經(jīng)驗(yàn)的不斷積累，電廠水網(wǎng)乃至輔網(wǎng)的監(jiān)控將向更加智能化、合理化和人性化趨勢發(fā)展。

We're exhausted24. It's good night time," Allison said. "Don't blow out the candles. I'll put new in tomorrow."
That night, in their bedroom, a few weeks earlier than had been predicted, Allison began to die. "Don't look at me if my wig comes off," she told Clark. "Please."
Her pulse cords were fluttering under his fingers. She raised her knees and kicked away the comforter. She said something to Clark about the garage being locked.
At the bephone, Clark had a b view out back and down to the porch. He wanted to get drunk with his wife once more. He wanted to bl her, from the greater perspective he had, that to own only a little talent, like his, was an awful, plaguing thing; that being only a little special meant you expected too much, most of the time, and liked yourself too little. He wanted to assure her that she had missed nothing.
He was speaking into the phone now. He watched the jack-o-lanterns. The jack-o-lanterns watched him.
