燃煤熱風爐改為天然氣熱風爐需要註意的事項

燃煤熱風爐曾經是我國熱風爐界的主流,但是隨著發展和环保事業的看重燃煤熱風爐漸漸推出瞭。而取代它的是使用天然氣為燃料的天然氣熱風爐,應為天然氣燃燒後隻會產生水和二氧化碳所以算是非常环保的燃料。在推廣天然氣熱風爐後就會有一些廠傢把之前燃煤的熱風爐改為天然氣的,但是在該的時候需要非常註意,不然容易發生事故。下面就來告訴你們燃煤熱風爐改為天然氣熱風爐需要註意的事項。Coal-fired hot-blast stoves used to be the mainstream in China's hot-blast stove industry, but with the development and environmental protection of the cause of the importance of coal-fired hot-blast stoves gradually introduced. It is replaced by a natural gas hot-blast stove using natural gas as fuel. It should be considered a very environmentally friendly fuel because natural gas burns only to produce water and carbon dioxide. After the promotion of natural gas hot blast stov彩色沥清地坪es, some manufacturers will change the former coal-fired hot blast stoves to natural gas, but at this time we need to pay close attention, otherwise accidents will occur easily. Next, Hua Shuai will tell you what matters needing attention in the conversion of coal-fired hot stove to natural gas hot stove.熱風爐燃料的燃燒改造是有科學依據和專業要求的,不能憑自己的想象或者不良商傢為瞭自己的蠅頭小利,不考慮熱風爐的獨特結構和燃燒方式,盲目亂改,把原來的燃燒室加煤口封死,在一側開一空直接將燃燒室噴火口插入燃燒室內,有的甚至於拆掉煙氣引煙風機,靠煙氣自然排放。The combustion transformation of hot blast stove fuel is based on scientific basis and professional requirements. We can't use our imagination or bad businessmen to make small profits without considering the unique structure and combustion mode of hot blast stove, blindly and indiscriminately alter the original combustion chamber feeding port, and directly insert the combustion chamber nozzle into the combustion chamber by opening an empty side. Some of them even remove smoke and smoke blower, and smoke naturally.短時間內貌似可以燃燒時用的,但存在諸多的隱患,一個是升溫時間長,浪費燃料；再就是煙氣的走向極端的不合理,導致不長的時間內換熱體的損壞。It seems that it can be used for combustion in a short time, but there are many hidden dangers. One is that the heating time is long and the fuel is wasted; the other is that the flue gas is irrational, which leads to the damage of heat exchanger in a short time.燃煤的火焰是沖上所以熱風爐是立式結構。而燃燒機噴射的火焰是水平走向,可想而知,火焰噴進燃燒室到對面的耐火材料後,順墻壁自然上行到熱風爐換熱區,那麼就產生瞭局部長期溫度過高,受熱壓力過大,而另一端火焰夠不到換熱效果極差的惡性循环。換熱效果差溫度上不去就要加大燃料耗量,形成惡性循环直至爐體燒漏、報廢。給企業造成不可估量的直接和間接損失。The flame of coal is rushing up, so the hot stove is a vertical structure. The flame sprayed by the burner moves horizontally. It can be imagined that when the flame sprays into the combustion chamber to the opposite refractory material, it naturally goes up along the wall to the heat transfer zone of the hot blast stove, then a vicious circle of excessive local long-term temperature, excessive heating pressure and insufficient heat transfer effect of the flame at the other end will occur. If the heat transfer effect is poor and the temperature does not go up, the fuel consumption will be increased, and a vicious cycle will be formed until the furnace body is burnt out and scrapped. It can cause incalculable direct and indirect losses to enterprises.不論改成燃氣熱風爐還是燃油熱風爐,鑒於火焰是水平走向,那麼熱風爐必須遵照火焰的走向,也就是改成臥式結構。為瞭降低高溫火焰對爐體內的吊膽等高溫區域的沖刷,燃燒機配套的燃燒室必須是特殊結構,適合這種燃燒方式。按要求可以配套電控設計成全自動一鍵操作,自動點火、自動控溫、自動調節運行工況,不僅僅是達到節能、降耗、操作便捷、省人工的優點,更主要的是大大縮短瞭升溫時間,降低瞭能耗,延長瞭熱風爐的使用壽命Whether converted to gas or oil-fired hot stove, the hot stove must follow the direction of flame, that is to say, to change to horizontal structure, in view of the horizontal direction of flame. In order to redu透水地坪ce the scouring of high temperature areas such as hanging galls in the furnace body by high temperature flame, the combustion chamber matched by the burner must be a special structure, which is suitable for this combustion mode. According to the requirements, electronic control can be designed to be a fully automatic one-key operation, automatic ignition, automatic temperature control and automatic regulation of operating conditions. It not only achieves the advantages of energy saving, consumption reduction, convenient operation and labor saving, but also greatly shortens the heating time, reduces energy consumption and prolongs the service life of hot blast stove.
