渣油燃燒器、干氣燃燒器在鍋爐行業的應用(簡要介紹)

?
-全自動比例調節燃料與空氣比:節約資金、利于環保

一、燃燒系統與控制的國際與國內趨勢:

王中王正版四不像图1、DAIBIAOSHIJIEXIANJINRANSHAOJISHUDEOUMEIGUOJIA-ANQUAN、GAOXIAO、HUANBAO、ZIDONG。

燃燒器均采用帶微分、積分計算或更為復雜運算調節儀器(例如:比例調節儀王中王正版四不像图、PLC、大型計算機控制等),通過對鍋爐的出水溫度、蒸汽壓力、蒸汽流量、煙氣中的氧含量、鍋爐給水系統等因素的檢測,同步連續動態調節燃料量和配風風量。一句話,燃燒工況只有隨著鍋爐工況、煙氣排放的變化而進行同步連續調節,才能達到高效、環保的效果。

6.3 手操式燃燒系統配風是一次風且不能自動調節,如此會造成火焰根部高溫區,并強烈的熱輻射,使油噴嘴溫度升高,重油高溫受熱會有碳析出,從而堵塞噴嘴,加大噴嘴磨損,加速噴槍損壞,造成維修費用的增加,對連續生產企業生產能力的提高是很大的障礙。

總結:分別對不同區域及時供應適量的空氣,以避免高溫缺氧而產生炭黑并能在最少的過量空氣下保證油的完全燃燒。燃油的燃燒的上述要求是通過燃燒器來達到的。油燃燒器主要由油霧化器和調風器所組成。燃油通過霧化器霧化成細油粒,以一定的霧化角噴入爐內,并與經過調風器送入的具有一定形狀的速度分布的空氣流相混合。油霧化器與調風器的配合應能使燃燒所需的大部分空氣及時地從火炬根部供入,并使火炬各處的配風量與油霧的流量密度分布相適應。同時也要向火炬尾部供應一定量的空氣,以保證炭黑和焦粒的燃盡。

·國內60 號以下,使用一般的機械壓力霧化方式,大部分燃燒器都可以作到;
·國內100號, 進口燃燒器因使用電子式溫度控制裝置控制燃油加熱,可以作到,并成功在世界各地應用;
·國內100 號以上重油/渣油/原油,必須采用的介質霧化或機械轉杯霧化;
·介質霧化燃燒器,采用壓縮空氣或蒸汽作為霧化介質,如進口Oilon;
·機械轉杯霧化燃燒器,采用高速轉杯進行機械霧化。
·機械壓力霧化燃燒器,采用高壓油泵進行壓力霧化。

以上比較可以得出如下結論:

·介質霧化油粒均勻,點火更容易;
·介質霧化更適合用在正壓燃燒的鍋爐上;
·介質霧化沒有高速運轉的部件,維護更加容易,費用更低;
王中王正版四不像图·介質霧化對燃料黏度幾乎沒有要求,更節約運行費用;
