    山东燃气锅炉和燃煤锅炉的区别
    来源:http://www.jnlzsb.com 发布时间:2019-04-12

    根据使用的燃料种类的不同,锅炉的命名也不尽相同,所以就有了燃煤锅炉和燃气锅炉这种不同类型的锅炉。那么这两种类型的锅炉除了在燃烧时使用的燃料不一样之外,燃煤锅炉和燃气锅炉之间还有什么区别呢?下面我们就看看山东燃气锅炉给我们的解释吧!
    According to the different types of fuel used, the names of boilers are different, so there are coal-fired boilers and gas-fired boilers, which are different types of boilers. So what is the difference between coal-fired and gas-fired boilers except for the different fuels used in the combustion of these two types of boilers? Now let's look at the explanation given by Shandong Gas Boiler.
    1.通风方式。燃煤锅炉一般采用负压燃烧,基燃烧过程是由鼓风机和引风机的配合来共同完成,煤在燃烧过程中,需要大量的空气,而由于炉墙烟道的漏风,过量空气系数可达2.1-2.5之间。燃气锅炉采用微正压或微负压燃烧,需要的风量小,在燃烧器内空气能较好的与天然气预混。微正压燃烧没有炉墙和烟道的漏风因素,运行中烟道出口空气系数可为1.05-1.2。
    1. Ventilation mode. Coal-fired boilers usually use negative pressure combustion. The basic combustion process is completed by the combination of blower and induced draft fan. Coal needs a lot of air in the combustion process. Because of the leakage of flue gas in the furnace wall, the excess air coefficient can reach between 2.1 and 2.5. Gas-fired boilers use micro-positive pressure or micro-negative pressure combustion, which requires less air flow, and air in the burner can be better premixed with natural gas. Micro-positive pressure combustion has no air leakage factor of furnace wall and flue, and the air coefficient of flue outlet in operation can be 1.05-1.2.
    2.热损不同。为了让燃煤锅炉保持足够的燃烧力度,需要使用人力或其他设备不停的往炉膛中添加燃煤,当需要间歇性运行的时候,再次启动时需要较长的时间来提高炉内温度,所以压火时会产生很大的热损,而燃气锅炉启停十分方便,间歇性运行时能够快速升温,从而降低这一过程中的热损。
    2. Different heat loss. In order to make the coal-fired boiler maintain enough combustion intensity, it is necessary to use human resources or other equipment to continuously add coal to the furnace. When intermittent operation is needed, it takes a long time to raise the temperature of the blast furnace when restarting, so there will be a great heat loss when pressing the fire. The gas-fired boiler is very convenient to start and stop, and can quickly raise the temperature during intermittent operation, so as to reduce this. Heat loss in a process.

    3.锅炉自动控制。燃煤锅炉由于受到煤种、料层厚度、鼓风量、引风量、风煤配比等原因,要做到根据负荷来自动调节锅炉运行参数的难度大。而燃气锅炉所受影响因素较少,可根据负荷调节燃烧器阀门大小,容易实现自动控制。
    3. Boiler automatic control. It is difficult for coal-fired boilers to automatically adjust the operating parameters of boilers according to load due to the reasons of coal type, material layer thickness, blast volume, induced air volume, air-coal ratio and so on. Gas-fired boilers are affected by fewer factors. The size of burner valve can be adjusted according to the load, which is easy to realize automatic control.
    4.排烟不同。燃煤锅炉使用的燃料就是煤,煤主要是由C、H、O、N、S等元素和灰分及水分组成,当煤燃烧之后会产生较大烟尘对环境造成严重的污染,但是,高稳定性的燃气锅炉在燃烧之后却没有黑烟排出,因为燃气基本上能够被完全燃烧,排烟的黑毒能够达到零林格曼级,里面的SO2含量非常少,所以对环境没有什么污染。
    4. Smoke exhaust is different. Coal is the fuel used in coal-fired boilers. Coal is mainly composed of C, H, O, N, S, ash and moisture. When coal is burned, it will produce a large amount of smoke and dust, which will cause serious pollution to the environment. However, high-stability gas-fired boilers do not emit black smoke after combustion, because the gas can basically be completely burned, and the black poison of smoke can reach zero Lingman grade. The SO2 content of noodles is very low, so there is no pollution to the environment.
