    燃煤热风炉改为天然气热风炉需要注意的事项

    燃煤热风炉曾经是我国热风炉界的主流,但是随着发展和环保事业的看重燃煤热风炉渐渐推出了。而取代它的是使用天然气为燃料的天然气热风炉,应为天然气燃烧后只会产生水和二氧化碳所以算是非常环保的燃料。在推广天然气热风炉后就会有一些厂家把之前燃煤的热风炉改为天然气的,但是在该的时候需要非常注意,不然容易发生事故。下面就来告诉你们燃煤热风炉改为天然气热风炉需要注意的事项。
    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 stoves, 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.
    热风炉燃料的燃烧改造是有科学依据和专业要求的,不能凭自己的想象或者不良商家为了自己的蝇头小利,不考虑热风炉的独特结构和燃烧方式,盲目乱改,把原来的燃烧室加煤口封死,在一侧开一空直接将燃烧室喷火口插入燃烧室内,有的甚至于拆掉烟气引烟风机,靠烟气自然排放。
    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.
    短时间内貌似可以燃烧时用的,但存在诸多的隐患,一个是升温时间长,浪费燃料;再就是烟气的走向极端的不合理,导致不长的时间内换热体的损坏。
    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.
    燃煤的火焰是冲上所以热风炉是立式结构。而燃烧机喷射的火焰是水平走向,可想而知,火焰喷进燃烧室到对面的耐火材料后,顺墙壁自然上行到热风炉换热区,那么就产生了局部长期温度过高,受热压力过大,而另一端火焰够不到换热效果极差的恶性循环。换热效果差温度上不去就要加大燃料耗量,形成恶性循环直至炉体烧漏、报废。给企业造成不可估量的直接和间接损失。
    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.
    不论改成燃气热风炉还是燃油热风炉,鉴于火焰是水平走向,那么热风炉必须遵照火焰的走向,也就是改成卧式结构。为了降低高温火焰对炉体内的吊胆等高温区域的冲刷,燃烧机配套的燃烧室必须是特殊结构,适合这种燃烧方式。按要求可以配套电控设计成全自动一键操作,自动点火、自动控温、自动调节运行工况,不仅仅是达到节能、降耗、操作便捷、省人工的优点,更主要的是大大缩短了升温时间,降低了能耗,延长了热风炉的使用寿命
    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 reduce 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.
