燃料種類對(duì)爐膛和燃燒設(shè)備有很大的影響。因此，不但要求發(fā)展各種爐型來適應(yīng)不同燃料的燃燒特點(diǎn)，而且還要提高燃燒效率以節(jié)約能源。此外，爐膛和燃燒設(shè)備的技術(shù)改進(jìn)還要求盡量減少鍋爐排中的污染物（硫氧化物和氮氧化物）。早年的鍋殼鍋爐采用固定爐排，多燃用質(zhì)量煤和木柴，加煤和除渣均用手工操作。直水管鍋爐出現(xiàn)后開始采用機(jī)械化爐排，其中鏈條爐排得到了的應(yīng)用。爐排下送風(fēng)從不分段的“統(tǒng)倉風(fēng)”發(fā)展成分段送風(fēng)。早期爐膛低矮，燃燒效率低。后來人們認(rèn)識(shí)到爐膛容積和結(jié)構(gòu)在燃燒中的作用，將爐膛造得較高，并采用爐栱和二次風(fēng)，從而提高了燃燒效率。鏈條爐排能適應(yīng)大多數(shù)煤種，但不能燒強(qiáng)粘結(jié)煤。下飼爐排也出現(xiàn)得很早，只適宜于燒質(zhì)量煤。40年代出現(xiàn)了拋煤機(jī)。拋煤機(jī)可以配在固定火床上，也可以配在鏈條爐排上而成為拋煤機(jī)鏈條爐排。發(fā)電機(jī)組功率超過6兆瓦時(shí)，以上這些層燃爐的爐排尺寸太大，結(jié)構(gòu)復(fù)雜，不易布置，所以20年代開始使用室燃爐，室燃爐燃燒煤粉和油。煤由磨煤機(jī)磨成煤粉后用燃燒器噴入爐膛燃燒，發(fā)電機(jī)組的容量遂不再受燃燒設(shè)備的限制。自第二次世界大戰(zhàn)初起，電站鍋爐幾乎全部采用室燃爐。蒸汽發(fā)生器早年制造的煤粉爐采用了U形火焰。</p><p> 將使汽溫降低。吹灰的目的為了防止受熱面結(jié)渣和積灰，改善鍋爐受熱面的傳熱效果，提高鍋爐熱效率，防止鍋爐水平道積灰無法排出而向爐膛倒塌使鍋爐滅火。吹灰順序從爐膛開始，順氣流向直至尾部。吹灰器成對(duì)動(dòng)作。2.鍋爐為何要進(jìn)行排污工作？連排的目的是排除爐水中溶解的部分鹽分，使?fàn)t水的含鹽量和堿度保持在規(guī)定值。定排的目的是排除爐水中沉淀物，調(diào)整爐水品質(zhì)，以補(bǔ)充連排之不足。3.實(shí)際工作中如何降低鍋爐的飛灰可燃物？1）在保證制粉出力的情況下盡量降低煤粉細(xì)度；2）適當(dāng)降低一次風(fēng)壓盡可能提高一次風(fēng)溫；3）保證足夠的二次風(fēng)量。在保持燃燒穩(wěn)定的情況下適當(dāng)開大中間二次風(fēng)擋板開度使風(fēng)粉充分混合；4）在保證汽溫、汽壓及負(fù)荷的情況下適當(dāng)降低上層給粉機(jī)轉(zhuǎn)速，加大下層給粉機(jī)轉(zhuǎn)速；5）適當(dāng)提高粉倉煤粉溫度；6）盡可能避免制粉系統(tǒng)堵煤及斷煤情況發(fā)生，保證制粉系統(tǒng)運(yùn)行的穩(wěn)定，維持合理的通風(fēng)量，減少三次風(fēng)量；7）不能一味追求再熱氣溫而將火嘴擺的太高，火焰中心上移，導(dǎo)致煤粉在爐膛停留時(shí)間減少，不能燃盡；8）合理控制爐膛氧量在4~6℃，使燃燒在爐膛充分燃燒；9）降低煤粉細(xì)度，比較好控制在煤粉經(jīng)濟(jì)細(xì)度，一般控制煤粉細(xì)度<10%。烏市防爆蒸汽發(fā)生器廠家。</p><div

使垢渣下的金屬表面始終處于潮濕狀態(tài)，同時(shí)垢渣又妨礙氧擴(kuò)散進(jìn)去，而垢渣周圍的金屬表面則有較充足的氧。這樣，由于氧的濃度差異，便形成了濃差腐蝕電池，渣垢周圍氧濃度大的部位為陰極，垢渣下氧濃度低的部位為陽極而使垢下金屬受到腐蝕。由上可知，要防止停用蒸汽發(fā)生器發(fā)生腐蝕，就應(yīng)使蒸汽發(fā)生器的金屬表面保持干燥和清潔，及時(shí)***水垢或堆積的水渣；對(duì)于濕法保護(hù)的，應(yīng)盡量降低水中的含鹽量，防止加速氧腐蝕。四、停用保養(yǎng)的基本原則1、阻止外界空氣進(jìn)入停用蒸汽發(fā)生器汽水系統(tǒng)內(nèi)；2、保持汽水系統(tǒng)內(nèi)金屬表面的干燥；3、在金屬內(nèi)表面形成具有防腐蝕作用的薄膜，以隔絕空氣；4、使金屬表面浸泡在含有除氧劑或其他保護(hù)劑的介質(zhì)中。五、停用腐蝕的防止、減輕方法為了防止或者減輕停用腐蝕，應(yīng)采用停爐保護(hù)措施。停爐保護(hù)的方法很多，主要分兩類：濕法保護(hù)和干法保護(hù)。濕法保護(hù)常用于停用時(shí)間較短的情況，例如一個(gè)月以內(nèi)。濕法保護(hù)常用的方法是將蒸汽發(fā)生器內(nèi)充滿除過氧的水，或含堿的水溶液，保持，以防止空氣漏入。如果停爐時(shí)間較長(zhǎng)，或天氣較冷，為防止凍壞設(shè)備，應(yīng)采用干法保護(hù)。方法是停爐后，水溫降到70~80℃時(shí)，將爐水全部放掉。吐魯番養(yǎng)護(hù)蒸汽發(fā)生器廠家。養(yǎng)護(hù)蒸汽發(fā)生器廠家</p><p

燃燒器噴出的煤粉氣流在爐膛中先下降，再轉(zhuǎn)彎上升。后來又出現(xiàn)了前墻布置的旋流式燃燒器，火焰在爐膛中形成L形火炬。隨著鍋爐容量增大，旋流式燃燒器的數(shù)目也開始增加，可以布置在兩側(cè)墻，也可以布置在前后墻。1930年左右出現(xiàn)了布置在爐膛四角且大多成切圓燃燒方式的直流燃燒器。60年代某些國家曾在多角形爐膛中應(yīng)用直流燃燒器的切圓燃燒方式，用以燃燒褐煤。第二次世界大戰(zhàn)后，石油價(jià)廉，許多國家采用燃油鍋爐。燃油鍋爐的自動(dòng)化程度容易提高。70年代石油提價(jià)后，許多國家又轉(zhuǎn)向利用煤炭資源。這時(shí)電站鍋爐的容量也越來越大，要求燃燒設(shè)備不僅能燃燒完全，著火穩(wěn)定，運(yùn)行可靠，低負(fù)荷性能好，還必須減少排中的污染物質(zhì)。40～60年代，為了強(qiáng)化燃燒和減少飛灰，一度采用液態(tài)排渣煤粉爐和旋風(fēng)爐，但由于采用這種燃燒方式生成的氮氧化物太多，從70年代起已較少采用。在燃煤（特別是燃褐煤）的電站鍋爐中采用分級(jí)燃燒或低溫燃燒技術(shù)，即延遲煤粉與空氣的混合或在空氣中摻氣以減慢燃燒?；虬讶紵鞣稚㈤_來爐溫，不但可氮氧化物生成，還能減少結(jié)渣。沸騰燃燒方式屬于一種低溫燃燒，除可燃用灰分十分高的固體燃料外，還可在沸騰床中摻入石灰石用以脫硫。克拉瑪依冷凝蒸汽發(fā)生器報(bào)價(jià)</p><p
