熱風爐初次使用應註意哪些問題？

熱風爐作為取暖設備,它的使用也是具有周期性的。每年寒冷的季節就是這種設備充分發揮其性能的時候,寒意一去它將轉入休眠狀態。那麼我們在每年開始使用的時候應該註意些什麼呢？ 1.在每一次休眠過後第一次使用的時候,我們都應該對燃燒室以及凈化室等高溫區域進行耐高溫防護措施,主要是耐火磚與耐火泥。在初次使用時,爐膛的溫度不宜上升過高過快,以免耐火材料的表面出現裂紋甚至發生崩裂的情況。As a heating device, the use of hot air stove is also cyclical. Every year in the cold season, when the equipment is fully functional, it will go to sleep when the chill goes away. So what should we pay attention to when we start using it every year? 1. When we use it for the first time after each dormancy, we should take high temperature protection measures for high temperature areas such as combustion chamber and purification chamber, mainly refractory bricks and refractory mud. In the initial use, the furnace temperature should not rise too high or too fast to avoid cracks or even cracks on the surface of refractories.2.在用煤方面,第一次使用和已經使用過一段時間的爐是有區別的。第一次使用最好使用一些質量較好的煤。不但是為瞭提高煤燃燒的效率,更重要的是需要選擇合適的燃煤。經過計算,我們發現粒徑在50-60mm的煤炭在燃煤熱風爐中燃燒最佳。對常見的固定爐箅熱風爐來說,各類煙煤、無煙煤以及褐煤都是可用的。2. there is a difference between the use of coal for the first time and the furnace that has been used for a period of time. For the first time, it is better to use some good quality coal. Not only to improve the efficiency of coal combustion, it is more important to choose the right coal. After calculation, we found that the coal with a diameter of 50-60mm is the best to burn in a coal-fired hot blast stove. For common fixed grate stoves, all kinds of bituminous coal, anthracite and lignite are available.3 .對煙筒的處理,長時間不使用,煙筒很可能會出現一些對於煙氣的處理問題。一般易度推薦的是濕法脫硫方法,這也是行業的主流方法。此外,對於煙氣除塵方法我們采用的水膜除塵器。3. For the treatment of flue gas, if the flue gas is not used for a long time, there may be some problems in the treatment of flue gas. The general recommendation is wet desulph彩色沥清地坪urization, which is also the mainstream method in the industry. In addition, we use the water film dust collector for flue gas dedusting.煤粉熱風爐與燃油燃氣熱風爐構造的區別Difference between pulverized coal hot blast stove and structure of fuel gas hot blast stove[1]、爐膛受熱面也有很大不同，由於比較復雜，在這就不在詳細解說。[1], furnace heating surface is also very different, because of the complexity, in this is not detailed 环氧地坪explanation.[2]、燃油熱風爐所配燃燒器必須有油物化器，而燃氣熱風爐所配燃燒器則無需物化器。[2] The burner of the oil-fired hot blast stove must have an oil physicochemical device, while the burner of the gas-fired hot blast stove does not need a physicochemical device.[3]、燃油熱風爐使用燃燒器，燃煤熱風爐中，有固定爐排、煤粉熱風爐以及沸騰爐等燃燒方法。[3] Oil-fired hot-blast stove uses burner. In coal-fired hot-blast stove, there are fixed grate, pulverized coal hot-blast stove and fluidized bed furnace combustion methods.[4]、燃油熱風爐一般沒有燃燼裝置，燃燒的廢氣通過煙囪排放。而燃煤熱風爐一般都有灰鬥、撈渣機等除灰設施。[4] and oil fired hot blast stoves generally do not burn out, and the exhaust gas is discharged through the chimney. Generally, there are ash handling facilities such as ash hopper and slag remover.[5]、燃油熱風爐與燃氣熱風爐，就本體結構而言沒有多大的區別，隻是由於燃料熱值不同，將受熱面作瞭相應的調整。即燃油熱風爐輻射受熱面積較大，而煤粉熱風爐則是將對流受熱面設計的大些。[5] There is not much difference between oil-fired hot blast stove and gas-fired hot blast stove in terms of body structure, but because of the different calorific value of fuel, the heating surface has been adjusted accordingly. That is to say, the radiation heating area of oil-fired hot blast stove is larger, while that of pulverized coal hot blast stove is larger.[6]、燃油熱風爐，必須配置一套較復雜的供油系統（特別是燃燒重油、渣油時），如油箱、油泵、過濾器加熱管道等，必須占據一定的空間，而燃氣熱風爐，則無需配置儲氣裝置。隻需將用氣管道接入供 氣網即可，當然，在管道上還需設置調壓裝置及電磁閥、緩沖閥等附件，以確保熱風爐安全運行。[6] Oil-fired hot blast stove must be equipped with a more complex oil supply system (especially when burning heavy oil and residue), such as fuel tank, oil pump, filter heating pipeline, etc. It must occupy a certain space, while gas-fired hot blast stove does not need to be equipped with gas storage device. It is only necessary to connect the gas pipeline to the gas supply network. Of course, pressure regulating devices, solenoid valves, buffer valves and other accessories should be installed on the pipeline to ensure the safe operation of the hot blast stove.
