          雖然我們經常都會使用到燃煤熱風爐,但是對它的一些方面可能并沒有那么的了解,所以很多時候都不能夠很好的使用它。今天小編在這里就來和大家講解一些關于燃煤熱風爐送風制度的知識,希望大家在看完之后可以知道具體是怎樣的。熱風爐作為熱動力機械的熱風爐于20世紀70年代末在我國開始廣泛應用,它在許多行業已成為電熱源和傳統蒸汽動力熱源的換代產品。熱風爐的基本送風制度有三種,可能你是不知道。燃煤熱風爐小編就給大家一一講述下。
          Although we often use coal-fired hot stove, but some aspects of it may not be so well understood, so many times it can not be used very well. Today, Xiaobian is here to explain some knowledge about the coal-fired hot blast stove air supply system. I hope you can know what it is after reading it. Hot blast stove, as a hot blast stove of thermodynamic machinery, began to be widely used in China in the late 1970s. It has become a replacement product of electric heat source and traditional steam power heat source in many industries. There are three basic air supply systems for hot stoves. Maybe you don't know. Coal-fired hot-blast stove Xiaobian will tell you one by one. 通過長時間的生產實踐,人們已經認識到,只有利用熱風作為介質和載體才能更大地提高熱利用率和熱工作效果。傳統電熱源和蒸汽熱動力在輸送過程中往往配置多臺循環風機,使之最終還是間接形成熱風進行烘干或供暖操作。
          Through long-term production practice, it has been recognized that only using hot air as medium and carrier can the thermal efficiency and thermal work effect be greatly improved. Traditional electric heat source and steam heat power are often equipped with multiple circulating fans in the process of conveying, which eventually form hot air for drying or heating operation indirectly.

          這種過程顯然存在大量浪費能源及造成附屬設備過多、工藝過程復雜等諸多缺點。而更大的問題是,這種熱源對于那種需要較高溫度干燥或烘烤作業的要求,則束手無策。
          Obviously, there are many shortcomings in this process, such as a large amount of waste of energy, excessive accessory equipment, complex process and so on. The bigger problem is that this heat source is at a loss for the requirement of drying or baking at higher temperatures.

          用碳化硅做的燃煤換熱器是一種新型的列管式高溫熱能回收裝置,可以廣泛用于冶金、機械、建材、化工等行業,直接回收各種工業窯爐排放的850-1400℃高溫煙氣余熱,以獲得高溫助燃空氣或工藝氣體。
          Coal-fired heat exchanger made of silicon carbide is a new type of tubular high-temperature heat recovery device, which can be widely used in metallurgy, machinery, building materials, chemical industry and other industries. It can directly recover the waste heat of high-temperature flue gas discharged from various industrial kilns at 850-1400 C, in order to obtain high-temperature combustion-supporting air or process gas.

          研制成的這種裝置的換熱元件材料系一種新型碳化硅工程陶瓷,它具有耐高溫和抗熱沖擊的優異性能,從 1000 ℃ 風冷至室溫,反復50 次以上不出現裂紋;導熱系數與不銹鋼等同;在氧化性和酸性介質中具有良好的耐蝕性。
          The heat exchange element material of this device is a new type of silicon carbide engineering ceramics, which has the excellent properties of high temperature resistance and thermal shock resistance. It has been air-cooled from 1000 to room temperature for more than 50 times without cracks. Its thermal conductivity is equal to that of stainless steel. It has good corrosion resistance in oxidizing and acidic media.

          在結構上成功地解決了熱補償和較好地解決了氣體密封問題。該裝置傳熱效率高,節能效果顯著,用以預熱助燃空氣或加熱某些過程的工藝氣體,可節約一次性能源,燃料節約率可達 30 %以上,并可強化工藝過程,顯著提高生產能力。
          Thermal compensation and gas seal are successfully solved in structure. The device has high heat transfer efficiency and remarkable energy saving effect. It can be used to preheat combustion-supporting air or to heat process gases. It can save disposable energy, save more than 30% of fuel, strengthen process and significantly improve production capacity.

          (1)交叉并聯送風(兩燒兩送制),適用于具有四座熱風爐的燃燒期 送風期熱處理爐燃燒期送風前期送風后期。
          (1) Cross-parallel air supply (two-firing and two-delivery system) is suitable for heat treatment furnaces with four hot stoves in the combustion period.

          (2)半并聯送風,適用于有三座熱風爐的高爐。
          (2) Semi-parallel air supply is suitable for blast furnaces with three hot stoves.

          (3)兩燒一送制,適用于具有三座熱風爐的高爐。
          (3) Two fires and one delivery system, suitable for blast furnaces with three hot stoves.

          三種基本送風制度讓大家在內部結構上又對熱風爐做了一定的了解。
          The three basic air supply systems allow us to have a certain understanding of the internal structure of the hot stove.

          以上就是對幾種燃煤熱風爐不同送風制度的方法介紹,這對它的使用來說其實是非常的重要的,大家在之后要注意了。
          Above is the introduction of several methods of different air supply systems of coal-fired hot stove, which is very important for its use. We should pay attention to it later.
