      低氮燃燒器改造后鍋爐與普通鍋爐的區別

      時間:2018-06-14 11:02    作者:admin 返回列表

            大家都知道低氮燃燒器主要應用于鍋爐中,市面上的低氮鍋爐成為眾多用戶的首要選擇。那么你知道低氮燃燒器改造后的鍋爐與普通鍋爐有哪些區別嗎?

      As we all know, low nitrogen burner is mainly used in boilers, and low nitrogen boiler on the market has become the primary choice for many users. Do you know the difference between the boiler after low nitrogen burner and the ordinary boiler?

      1、排放的差異:

             由于層燃、室燃、循環流化床鍋爐的燃燒方式不同、爐膛結構不同,其原始NOx排放也有較大差異,一般來說,在未特意采用爐內低氮燃燒技術時,循環流化床NOx原始排放低,以鏈條爐為代表的層燃爐NOx原始排放也略低,煤粉工業鍋爐為室燃鍋爐,NOx原始排放越高,國內知名的低氮鍋爐都排放卻大大降低。

      1. Differences in emissions:

              Because of the different combustion modes and the different furnace structure, the original NOx emission of the layer combustion, the chamber combustion and the circulating fluidized bed boiler is different. Generally speaking, the original emission of the circulating fluidized bed NOx is low when the low nitrogen combustion technology is not specially used in the furnace, and the original emission of the NOx in the layer combustion furnace represented by the chain furnace is also slightly lower. Industrial boilers are chamber fired boilers, and the higher the NOx's original emissions, the less well-known domestic low nitrogen boilers are.

      2、鍋爐技術不同:

             層燃、室燃、循環流化床鍋爐可根據燃燒方式的不同采用不同的低氮燃燒技術,針對層燃鍋爐配風較常采用空氣分級以及煙氣再循環來實現低氮燃燒;在煙氣再循環對層燃鍋爐典型區段燃燒的影響下,結合空氣分級技術通過半焦催化還原NOx;爐內超級還原脫硝技術是近年來新興的爐內脫硝技術手段,通過在燃燒火焰區域的合理位置噴氨,實現在高溫火焰中直接脫硝。低氮鍋爐主要對二次風口、給煤口的位置及分布進行優化調整,或是增加煙氣再循環系統等。

      2. The technology of boiler is different:

             Different low nitrogen combustion technology can be used in the layer combustion, room combustion and circulating fluidized bed boiler according to the different combustion modes. The low nitrogen combustion is realized by air classification and gas recirculation for the air distribution of the layer combustion boiler. Under the influence of the combustion of the typical section of the layer combustion boiler, the gas recirculation is combined with the air classification technology to pass the semi coke. Catalytic reduction of NOx, the technology of super reduction and denitrification in the furnace is a new technology for denitrification in the furnace in recent years. By spraying ammonia at a reasonable position in the burning flame area, the direct denitrification can be achieved in the high temperature flame. The low nitrogen boiler mainly adjusts and adjusts the location and distribution of the two outlets, coal outlets, or increases the flue gas recirculation system.

      3、安全性不同

            中心在對層燃、室燃、循環流化床鍋爐的爐內低氮燃燒技術進行了大量試驗后,已在工程應用上加以驗證,總體來說低氮鍋爐,安全性要更高一些,之所以近年來它的銷量越來越高,有眾多用戶是因為它的安全性高,對空間環境的威脅小而購買,這也是它與普通鍋爐的重要差異之一。

            低氮鍋爐技術創新產品,是生產節能環保型產品的根本所在,低氮鍋爐技術經過多次大量的試驗和工程應用上的驗證,已經取得了很大的成果,低氮鍋爐在很多產業上有了廣泛的運用,不僅保護了環境,節能,還控制了污染,這項技術也特別值得我們為之繼續進行研究和開發應用。

      3. Different security

             After a lot of experiments on low nitrogen combustion technology in the furnace of layer combustion, room combustion and circulating fluidized bed boiler, the center has been verified in engineering application. In general, the low nitrogen boiler has a higher safety. In recent years, its sales volume is higher and higher. There are many users because of its high safety and space ring. The threat of the environment is small and the purchase is also one of the important differences between it and ordinary boilers.

      The technology innovation product of low nitrogen boiler is the root of the production of energy saving and environmental protection products. The low nitrogen boiler technology has made great achievements in many experiments and engineering applications. The low nitrogen boiler has been widely used in many industries, not only protecting the environment, saving energy, but also controlling the pollution. This technology is also worthy of our continued research and development.
