再來說一下千瓦的概念，早期它是作為電的功率單位，后來延伸到了整個(gè)物理領(lǐng)域功率的單位。在單位換算中1KW=1000W，1W的定義是1J/s，相對(duì)應(yīng)的1KW=1000J/s=3600KJ/h，到這里再來看一下熱負(fù)荷的概念，就不難想明白燒嘴中熱負(fù)荷和千瓦的聯(lián)系了。焦耳作為國(guó)際通用單位在全世界都在使用，致誠(chéng)熱能經(jīng)常碰到一些老工程師些喜歡使用卡作為能量單位，所以有些工程師提高燒嘴的功率時(shí)經(jīng)常說多少多少大卡的設(shè)備。也有直接說單位時(shí)間燒嘴的耗氣量的，這種表達(dá)一般都能理解。如以230KW天然氣燒嘴為例，它的熱負(fù)荷是230KW，即每小時(shí)熱負(fù)荷82.8萬千焦熱量，用大卡的單位表示是每小時(shí)約20萬大卡熱量，相應(yīng)的每小時(shí)消耗的天然氣約23立方。了解完這些，對(duì)燃燒器功率單位方面的問題應(yīng)該就能解決了，再進(jìn)行設(shè)備選型及咨詢時(shí)不至于一頭霧水了。點(diǎn)火燒嘴損壞的原因：當(dāng)燃料中焦?fàn)t煤氣配比的增多，燃燒得到了強(qiáng)化，燃燒器局部溫度升高，點(diǎn)火燒嘴被燒壞；山東燃?xì)鉄靾?bào)價(jià)</p><p
