style="text-indent:25px">在我國，有全部使用沼氣的單燃料沼氣發(fā)電機組及部分使用沼氣的雙燃料沼氣-柴油發(fā)電機組。單燃料工作原理及優(yōu)點將“空氣沼氣”的混合物在氣缸內(nèi)壓縮，用火花塞使其燃燒，通過火塞的往復運動得到動力，然后連接發(fā)電機發(fā)電。①不需要輔助燃料油及其供給設備。②燃料為一個系統(tǒng)，在控制方面比可燒兩種燃料的發(fā)電機組簡單。③發(fā)電機組價格較低。雙燃料工作原理優(yōu)點：將“空氣燃燒氣體”的混合物在氣缸內(nèi)壓縮，用點火燃料使其燃燒，通過火塞的往復運動得到動力，然后連接發(fā)電機發(fā)電。①用液體燃料或氣體燃料都可工作。②對沼氣的產(chǎn)量和甲烷濃度的變化能夠適應。③如由用氣體燃料轉(zhuǎn)為用柴油燃料在停止工作，發(fā)電機組內(nèi)不殘留未燃燒的氣體。</p><p style="text-indent:25px">沼氣燃燒發(fā)電是隨著大型沼氣池建設和沼氣綜合利用的不斷發(fā)展而出現(xiàn)的一項沼氣利用技術，具有高效、節(jié)能、安全和環(huán)保等特點。沼氣中含有硫化氫，具有強烈腐蝕性，在燃燒后會污染環(huán)境，并對人的身體健康產(chǎn)生不利影響。所以，脫硫設備成為搭配沼氣發(fā)電機組使用的*****。1、經(jīng)過作為管道系統(tǒng)的液體阻火器“水封”，保證系統(tǒng)安全運行；2、經(jīng)過氣水分離器，以避免脫硫劑泥化現(xiàn)象；3、經(jīng)過裝有氧化鐵的脫硫罐，發(fā)生化學反應進行脫硫；4、處理合格的沼氣經(jīng)過羅茨風機增壓，保護發(fā)電機組正常運行；5、通過穩(wěn)壓罐來維持系統(tǒng)的壓力，穩(wěn)壓罐可以瞬間補氣，保證氣源的穩(wěn)定性，為沼氣發(fā)電機組良好運行提供了堅實的基礎。沼氣發(fā)電機工作原理是沼氣經(jīng)脫硫器由貯氣罐供給燃氣發(fā)電機組。</p><div

style="text-indent:25px">天然氣發(fā)電機組的和柴油發(fā)電機組等一樣是發(fā)電設備，二者各有優(yōu)勢。下面沼氣發(fā)電機組給用戶介紹一下天然氣發(fā)電機組的使用過程中應該注意的事項有哪些？1、為了保證一定安全，天然氣發(fā)電機組機房應遠離明火區(qū)域；2、做好室內(nèi)安裝照明、開關、線路及其電器應的防爆措施；3、完善消防措施，配備滅火器等消防器械；4、燃氣發(fā)電機組機房內(nèi)安裝可燃氣體報警裝置，可燃天然氣發(fā)電機組氣體泄露時能及時發(fā)現(xiàn)。5、較好選擇寬敞、明亮且要求安裝換氣扇以保證良好的通風，有助機組的使用；6、天然氣發(fā)電機組安裝時底盤與地基應用平墊鐵找平，接觸面積應在60%以上，且分布均勻。沼氣是一種主要有效成分為甲烷的可燃混合氣體, 甲烷占50%~70%, 二氧化碳占25%~50%。石家莊農(nóng)村沼氣**發(fā)氣機</p><p style="text-indent:25px">沼氣里面的硫主要是以硫化氫(H2S)的形式存在，分子式為H2S。石家莊農(nóng)村沼氣**發(fā)氣機</p><p style="text-indent:25px">在利用沼氣發(fā)電過程中，由于沼氣發(fā)電機組本身設計和材料的特點，導致發(fā)電機組對沼氣中的部分成分（如H2S、水分、固體雜質(zhì)等）特別敏感，如果處理不好將導致發(fā)電機組無法正常運行。硫化氫（H2S）是一種無色有毒的可燃性氣體，具有強烈的臭雞蛋氣味，當空氣中硫化氫的體積含量超過0.1%時，就能引起頭疼暈眩等中毒癥狀。硫化氫（H2S）對鐵等金屬有強腐蝕性，也易吸附金屬表面與多種金屬離子作用，生成不溶于水的硫化物沉淀。沼氣在燃燒時，其中的H2S還能轉(zhuǎn)化為腐蝕性很強的亞硫酸氣霧會污染環(huán)境和腐蝕機器設備，同時H2S在潮濕的環(huán)境下對金屬管道、燃燒設備、檢測設備和儀表等都具有強烈的腐蝕性，所以沼氣在利用前必須脫出其中所含的H2S。利用沼氣發(fā)電時沼氣中的硫化氫會對沼氣發(fā)電機組的進氣管道、增壓器、中冷器、火花塞、氣缸套、排氣管和消音器等造成嚴重腐蝕影響機組壽命。所以沼氣在進入發(fā)電機組之前必須進行沼氣預處理，將H2S降到機組允許的范圍內(nèi)才能保證機組的可靠運行。石家莊農(nóng)村沼氣**發(fā)氣機</p><p
