燃煤热风炉改燃气热风炉的方法技巧

2019-04-07 11:08:43 常州亿创能源科技有限公司 阅读

燃煤热风炉曾经是我国主要的生活供热和工业生产所用的热风炉。每年因为使用燃煤热风炉所消耗的煤炭总量为6亿吨。据不完全统计,我国工业燃煤热风炉的总量为60万台。可见燃煤热风炉在我国工业生活中所占比重之大,覆盖之广。而这些热风炉运行时所产生的热效率普遍比燃气热风炉要低得多,排放的污染物却成倍增加。因此,燃煤热风炉改造成燃气热风炉是势在必行了。从中央到地方,各级政府机关全都积极的投身到燃气热风炉改造的大潮当中,为了减少污染排放,提高生产效率尽自己的一份力。

Coal-fired hot-blast stoves used to be the main domestic heating and industrial production hot-blast stoves in China. The total amount of coal consumed annually by using coal-fired hot stoves is 600 million tons. According to incomplete statistics, the total number of industrial coal-fired hot blast stoves in China is 600,000. It can be seen that the proportion of coal-fired hot blast stoves in China's industrial life is large, covering a wide range. The thermal efficiency of these stoves is generally much lower than that of gas-fired stoves, but the pollutants discharged from these stoves are doubled. Therefore, it is imperative to transform coal-fired hot blast stove into gas-fired hot blast stove. From the central government to the local government, all levels of government organs are actively involved in the tide of gas hot stove transformation, in order to reduce pollution emissions, improve production efficiency to do their part.

那燃煤热风炉改造成燃气热风炉的好处有什么呢?让我和你细数热风炉改造的优势。

What are the advantages of transforming a coal-fired hot stove into a gas-fired hot stove? Let me count the advantages of transforming a coal-fired hot stove with you.

1.热风炉热效率的提升。燃气热风炉和燃煤热风炉相比,有一个优势,那就是燃气热风炉的热效率要高于一般的燃煤热风炉。热风炉热效率的提升,能帮助企业提高工作效率,降低工业成本。

1. Improvement of thermal efficiency of hot blast stove. Compared with coal-fired hot stove, gas-fired hot stove has one advantage, that is, the thermal efficiency of gas-fired hot stove is higher than that of general coal-fired hot stove. The improvement of thermal efficiency of hot blast stove can help enterprises improve work efficiency and reduce industrial costs.

2.热风炉污染物排放量降低。众所周知,天然气燃烧所产生的污染物比煤炭燃烧所产生的污染物要少的多。天然气燃烧主要产生水和二氧化碳,方便废气处理。而燃煤热风炉需要脱硫,净化等一系列工序才能安全排放。

2. Reduction of pollutant emission from hot blast stove. It is well known that the pollutants produced by natural gas combustion are much less than those produced by coal combustion. Natural gas combustion mainly produces water and carbon dioxide, which is convenient for waste gas treatment. The coal-fired hot blast stove needs a series of processes such as desulfurization and purification to discharge safely.

3.政府给予环保补贴或奖励。企业改造热风炉,政府帮忙补贴。已经成为现今各级政府都会做的事情了。政府补贴降低了企业改造热风炉的费用,受益的企业当然心甘情愿的改造燃气热风炉。

3. The government gives environmental protection subsidies or incentives. Enterprises renovate hot stoves and the government subsidizes them. It has become something that governments at all levels can do today. Government subsidies have reduced the cost of rebuilding hot stoves for enterprises, and the beneficiary enterprises are certainly willing to rebuild gas hot stoves.

4.天然气管道的铺设,原料供给方便。各大城市现在都在提高天然气的供给管道铺设工作。以后天然气的供给将成为主流。比起,一车一车运送煤炭。管道运输天然气安全,整洁,环保,高效。

4. The laying of natural gas pipeline facilitates the supply of raw materials. Major cities are now improving the laying of natural gas supply pipelines. The supply of natural gas will become the mainstream in the future. By contrast, coal is transported by car. Pipeline transportation of natural gas is safe, clean, environmentally friendly and efficient.

燃煤热风炉改烧天然气的注意事项

Notices for Converting Coal-fired Hot-blast Stove to Natural Gas

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 not rely on our imagination or bad businessmen for their own small profits, regardless of the unique structure and combustion mode of hot blast stove, blindly change, seal the original combustion chamber feeder, and insert the combustion chamber nozzle directly into the combustion chamber by opening an empty side, or even remove the flue gas to induce smoke. Machine, natural emission by flue gas.

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。

Coal-fired flame is flushed onto all hot stoves which are vertical structures. 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 causes inestimable direct and indirect losses to enterprises.

不论改成燃气还是燃油,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 fuel, the hot blast stove must follow the direction of the flame, that is, to change to a horizontal structure, in view of the horizontal direction of the 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.
