          燃煤熱風爐的選用方法雖然不是很復雜,但是大家在選擇的時候如果不想出現意外的話,可以先看一看在選擇的過程之中需要注意的原則有哪些了。下面的這些內容就是當我們在選擇燃煤熱風爐的時候一定要遵守的幾個原則。每種燃煤熱風爐都有其特定的適用范圍,而每種物料都可找到若干種能滿足基本要求的燃煤熱風爐,但最適合的只能有一種。如選型不當,用戶除了要承擔不必要的一次性高昂采購成本外,還要在整個使用期內付出沉重的代價,諸如效率低、耗能高、運行成本高、產品質量差、甚至裝置根本不能正常運行等等。燃煤熱風爐小編帶大家了解關于燃煤熱風爐選型的九項原則。
          Although the selection method of coal-fired hot blast stove is not very complicated, if you don't want to have any accidents in the selection process, you can first look at the principles that need attention in the selection process. The following are some principles that we must abide by when choosing a coal-fired hot blast stove. Each kind of coal-fired hot-blast stove has its specific application scope, and each material can find several kinds of coal-fired hot-blast stoves which can meet the basic requirements, but the most suitable one can only be found. For example, improper selection, users should not only bear the unnecessary one-time high procurement costs, but also pay a heavy price in the whole service life, such as low efficiency, high energy consumption, high operating costs, poor product quality, and even the normal operation of the device and so on. We all know about the nine principles of selection of coal-fired hot blast stoves. 1.選型前最好能做出物料的干燥實驗,深入了解類似物料已經使用的燃煤熱風爐(優缺點),往往對恰當選型有幫助。
          1. It's better to do drying experiments of materials before type selection. It's often helpful to know the advantages and disadvantages of coal-fired hot blast stoves that have been used for similar materials.

          2.不完全依賴過去的經驗,注重吸收新技術,多聽專家的意見。
          2. Not totally dependent on past experience, pay attention to absorbing new technologies and listen to experts'opinions.

          3.耗能低-------不同干燥方法耗能指標不同,一般傳導式干燥的熱效率理論上可達100%,對流式干燥只能70%左右。
          3. Low energy consumption - - - different drying methods have different energy consumption indicators. The thermal efficiency of conductive drying can reach 100% theoretically, and convective drying can only reach about 70%.

          4.節省投資-----完成同樣功能的燃煤熱風爐,有時其造價相差懸殊,應擇其低者選用。
          4. Save investment - --- Coal-fired hot blast stoves with the same functions are sometimes very different in cost, so the lower one should be chosen.

          5.運行成本低---設備折舊、耗能、人工費、維修費,備件費…等運行費用要盡量低廉。
          5. Low operating costs - depreciation of equipment, energy consumption, labor costs, maintenance costs, spare parts costs. The operation cost should be as low as possible.

          6.干燥速率高---僅就干燥速率看,對流干燥時物料高度分散在熱空氣中,臨界含水率低,干燥速度快,而且同是對流干燥,干燥方法不同臨界含水率也不同,因而干燥速率也不同。
          6. High drying rate - In terms of drying rate, materials are highly dispersed in hot air during convective drying. The critical moisture content is low and the drying speed is fast, and the same convective drying method has different critical moisture content, so the drying rate is different.

          7.優先選擇結構簡單、備品備件供應充足、可靠性高、壽命長的燃煤熱風爐。
          7. Priority should be given to coal-fired hot stoves with simple structure, adequate spare parts supply, high reliability and long service life.

          8.適用性-------燃煤熱風爐首先必須能適用于特定物料,且滿足物料干燥的基本使用要求,包括能很好的處理物料(給進、輸送、流態化、分散、傳熱、排出等),并能滿足處理量、脫水量、產品質量等方面的基本要求。 9.符合環保要求,工作條件好,安全性高。
          8. Applicability - - - Coal-fired hot blast stove must first be suitable for specific materials, and meet the basic requirements of material drying, including good handling of materials (feed, transport, fluidization, dispersion, heat transfer, discharge, etc.), and can meet the basic requirements of processing capacity, dehydration capacity, product quality and so on. 9. It meets the requirements of environmental protection, has good working conditions and high safety.
