            煤粉鍋爐對(duì)爐膛的結(jié)構(gòu)要求

                   煤粉鍋爐對(duì)爐膛的結(jié)構(gòu)要求:
                   1、合理布置燃燒器,使燃料很快著火:有良好的爐內(nèi)空氣動(dòng)力場(chǎng)使各壁面的熱負(fù)荷均勻;既要使火焰在爐膛的充滿度好、減少氣流的死滯區(qū)。又要不讓火焰沖墻、結(jié)渣。
                   2、爐膛要有容積和高度以保障燃料在爐內(nèi)的停留時(shí)間并燃燒。
                   3、能夠布置適當(dāng)?shù)恼舭l(fā)受熱面滿足鍋爐容量的要求:爐膛出口煙氣溫度適當(dāng)以確保護(hù)膛出日及以后受熱面不結(jié)渣和安全工作。
                   4、爐膛結(jié)構(gòu)緊湊,金屬及其他材料用量少;便于制造、安裝、操作和維護(hù)。
