循環(huán)流化床鍋爐是被國(guó)際公認(rèn)的高效、低污染的清潔燃燒技術(shù)，是國(guó)家重點(diǎn)鼓勵(lì)和發(fā)展的環(huán)保節(jié)能項(xiàng)目。該鍋爐具有燃燒效率高，負(fù)荷調(diào)節(jié)范圍大，無(wú)需加裝脫硫、脫硝裝置即可實(shí)現(xiàn)90%脫硫率，滿足環(huán)保要求，以經(jīng)濟(jì)的方式解決大氣污染題目，而且煤種適應(yīng)性廣，排出的灰渣活性好，輕易實(shí)現(xiàn)綜合利用。目前國(guó)內(nèi)300MW等級(jí)循環(huán)流化床鍋爐消化引進(jìn)阿爾斯通技術(shù)，和常規(guī)煤粉鍋爐相比主要在燃燒系統(tǒng)方面存在差異其具有如下特點(diǎn)：

 

             通常鍋爐四角分別布置4個(gè)返料器和4個(gè)外置流化床，外置床中布置了中溫過(guò)熱器，低溫過(guò)熱器和高溫再熱器等鍋爐受熱面。

 

             鍋爐左右兩側(cè)配有風(fēng)道燃燒器，每側(cè)風(fēng)道燃燒器含有兩支油槍，床上左右兩側(cè)各配有4支床上油槍。

 

             風(fēng)煙系統(tǒng)中一次風(fēng)作為主要流化風(fēng)，二次風(fēng)分上中下分級(jí)送風(fēng)助燃，多路流化風(fēng)對(duì)返料器、外置床等受熱室起到流化作用。

 

             風(fēng)煙系統(tǒng)中灰循環(huán)的公道建立是鍋爐穩(wěn)定燃燒的重要條件，也是控制床溫、再熱汽溫的基礎(chǔ)。

 

             由于循環(huán)流化床鍋爐的復(fù)雜性，鍋爐爐膛安全監(jiān)測(cè)系統(tǒng)和常規(guī)煤粉爐有較大差別，包含鍋爐跳閘BT、送風(fēng)跳閘AT和主燃料跳閘MFT三個(gè)主要跳閘信號(hào)。

 

             由于循環(huán)流化床鍋爐的大滯后特性，自動(dòng)控制難點(diǎn)在協(xié)調(diào)控制，床溫控制、床壓控制、過(guò)熱汽溫控制和再熱汽溫控制。

 

             對(duì)于循環(huán)配套直接空冷系統(tǒng)，直接空冷的控制關(guān)鍵在于風(fēng)機(jī)轉(zhuǎn)速主指令控制，即如何設(shè)定好背壓是一個(gè)關(guān)鍵，既能夠考慮到汽輪機(jī)效率，又能考慮到風(fēng)機(jī)電耗率，達(dá)到一個(gè)最佳經(jīng)濟(jì)性指標(biāo)，同時(shí)兼顧到低溫防凍保護(hù)。

             蒙西DCS項(xiàng)目由DAS、FSSS、SCS、MCS、DEH、ECS、ACC等部分組成，總點(diǎn)數(shù)約20000點(diǎn)，采用TPS系統(tǒng)，總配置單元機(jī)組配置控制器18×2對(duì),公用系統(tǒng)配置控制器2對(duì)，ACC配置控制器2×2對(duì)，操縱員站6×2臺(tái)，工程師站2×2臺(tái)，OPC接口服務(wù)器1×2臺(tái)。單元機(jī)組系統(tǒng)配置如下圖所示。
