    锅炉经过长时间运行,不可避免会出现水垢、锈蚀问题,而这是引起锅炉事故的主要原因之一。我公司作为专业的锅炉厂家,为了引起广大用户对锅炉水垢的重视,下面由锅炉厂家的专业人员给大家介绍一下锅炉水垢的危害性,主要表现在:
    The boiler after long time operation, inevitably there will be a scale and corrosion problem. And this is one of the main causes of boiler accidents. My company as a professional manufacturer of boiler, in order to cause the majority of users pay attention to the boiler scale, following by the boiler manufacturers professionals to introduce the harm of boiler scale, mainly in:
    1、浪费大量燃料
    1, waste a lot of fuel
    因为水垢的导热系数只有钢材的几十分之一,所以当受热面结垢后会使传热受阻,为了保持锅炉一定的出力,就必须提高火侧的温度,从而使向外辐射及排烟造成热损失。由于锅炉的工作压力不同,水垢的类型及厚度不同,所浪费的燃料数量不同,根据试验和计算,随着水垢厚度的增加,损耗的燃料也不断增加。
    Because one of the scores of the scale of the thermal conductivity of steel only, so when the heating surface fouling will cause heat transfer is blocked, in order to maintain the output of boiler, it is necessary to improve the fire side temperature, so that the outward radiation and exhaust heat loss caused by. Because the boiler working pressure of different types and different thickness scale, the number of wasted fuel, according to the test and calculation, with the increase of the thickness of the scale, the loss of fuel is increasing.
    2、容易使钢板、管道因过热而被烧损
    2, easy to make steel, pipeline due to overheating and burning
    因为锅炉结垢后,又要保持一定的工作压力及蒸发量,所以只能提高火侧的温度,但是水垢越厚,导热系数越低,火侧的温度就越高。一般说来锅炉火侧的温度在900℃左右,而水侧的温度在190℃左右。当没有水垢时钢板的温度在230℃左右,一旦结垢1mm左右,钢板的温度比无垢时提高了140℃左右。当到达一定的温度时,金属的各项可塑性指标开始下降,而且温度再高,金属会因过热而蠕动变形。所以锅炉结垢是很容易使金属被烧损的。
    Because the boiler scale, but also maintain a certain working pressure and evaporation, so can improve the temperature of the fire side, but the scale is thicker, the thermal conductivity is low, the higher the temperature the fire side. Generally speaking, the temperature of the fire side of the boiler is about 900 DEG C, and the temperature of the water side is about 190 degrees celsius. When no furring plate temperature at 230 degrees Celsius, once the scale of about 1mm, the temperature of the steel plate than the non scale increase of 140 degrees celsius. When the temperature reaches a certain temperature, the metal plasticity index began to decline, and the temperature is too high, the metal will creep deformation due to overheating. So the boiler scaling is easy to make the metal burning.
    3、增加检修费用和降低使用寿命
    3, increase maintenance costs and reduce service life
    锅炉因水垢而引起的事故大约占锅炉事故总数的三分之一,还有上升趋势,锅炉事故不但造成设备的损坏,也威胁到人身的安全。
    Due to scale boiler accidents caused by boiler accidents accounted for about 1/3 of the total, there is an upward trend, the boiler accidents not only caused damage to the equipment, but also a threat to personal safety.
    因此,在给水合格的情况下,锅炉运行时应严格控制锅内用水达到国家标准;并在运行中防止水垢的生成,而且结垢后,需及时进行处理,必须彻底防止及清除锅炉炉内水垢及控制水质。要解决以上问题,目前最科学的方法是在锅炉运行加入综合性能好,功效全面的药剂运行保养及定期清洗除垢。
    Therefore, in the case of qualified water supply, boiler operation should strictly control the water to reach the national standard; and to prevent the generation of scale in operation, and after scaling, need timely treatment, to completely prevent and remove scale and quality control of boiler furnace. To solve the above problems, the most scientific method is added in the boiler operation good comprehensive performance, operation and maintenance of drug efficacy of a comprehensive and regular cleaning.
    通过了解锅炉的危害性,所以相关人员在使用锅炉时一定要做好锅炉的清洗和保养工作。锅炉厂家提醒大家,锅炉使用安全决不可大意。
    Through the understanding of the hazards of the boiler, so the relevant personnel in the use of the boiler must do a good job of cleaning and maintenance of the boiler. Boiler manufacturers to remind you that the use of boiler safety must not be careless.
