中航豫泓海绵铁滤料适用范围：
1、适用于热水锅炉的补水;
2、适用于低压蒸汽锅炉的给水;
3、适用于工业循环冷却水补水;
4、适用于油田注水含铁量超过97％以上也属于海绵铁，但应用于粉末冶金领域，其形状分块状和粉状
中航豫泓告诉您为什么要严格控制锅炉补水水质？
(1)防止结垢，如果进入的水质不符合标准，而又未及时正确处理，则经一段是境运行后，在和水接触的受传热面上，会生成一层固体的附着物--水垢，由于水垢的导热性能很差，比金属
要相差几百倍。因此，使得结垢部位温度过高，引起金属强度下降，局部变形。产生鼓泡，严重的还会引起爆裂事故，危及安全运行；结垢还会严重影响锅炉换热效果，大大地降低锅炉地的
经济，如在省煤器中结有1MM厚水垢，燃料就得多耗1.5%---2.0%；由于结垢会使汽轮机凝汔器内真空度降低，从而使机的热交率和出力降低。严重时，甚至要被近停产进行检修有，因此，控
制水质防止结垢十分重要。
(2)防止腐蚀。锅炉给水水质不良，会造成省煤器水冷壁、给水管道、加热器、过热器、过热器以及汽轮机冷凝器等的腐蚀。腐蚀不令要缩短设备的使用寿命，造成经济损失，同时腐蚀产
物又会转入水中污染水质，从而虽剧了受热面上的结垢，结垢又促进了垢下腐蚀，造成腐蚀和结垢的恶性循环。
(3)防止积盐。锅炉给水中的超量杂质和盐分，随蒸汽带出而沉积于过热器和汽轮机中，这种现象称为积盐，过热器的积盐会引起金属管壁过热，甚至爆裂；汽轮机内积盐会降低出力和效
率，严重的会造成事故。
Yu Hong is AVIC sponge iron:
Sponge iron backwashing frequency is low, high compressive strength, no powder, no hardening, large specific surface area. High activity, good regeneration effect, in line with the national standard of boiler water quality. The sponge iron deoxidizing agent after activation treatment, to polycellular sponge iron particle, water
Dissolved oxygen provides the opportunity to react with the active iron and accelerates the redox reaction.
AVIC Yu Hong applicable sponge filter iron range:
1, suitable for hot water boiler water;
2, suitable for low pressure steam boiler feed water;
3, suitable for industrial circulating cooling water;
4, suitable for oil field water injection of iron content more than 97% also belong to sponge iron, but applied to the field of powder metallurgy, the shape of the block and powder
AVIC Yu Hong tell you why to strictly control the boiler make-up water-
(1) to prevent fouling, if the water quality does not meet the standards, and timely and correct treatment, then after a period of operation after the exit is in contact with the water, the heat transfer surface, will generate a solid layer of attachment, scale, scale due to thermal conductivity is poor than metal
To a difference of several hundred times. Therefore, the temperature is too high, causing the metal strength to drop, local deformation. Bubble burst, serious will also cause the burst accident, endanger the safe operation; scale will seriously affect the boiler heat transfer effect, greatly reduce the
The economy, as in the economizer with 1MM thick scale, more fuel consumption 1.5%---2.0%; due to fouling will make the steam turbine condensate is the vacuum degree in gas is reduced, so that the machine heat exchange rate and output decreased. Serious, even to be close to the maintenance of production, therefore, control
Water quality prevention is very important.
(2) to prevent corrosion. The quality of boiler water side economizer, caused by the corrosion of water wall, a water supply pipe, heater, superheater, superheater and steam turbine condenser. Corrosion does not make to shorten the service life of equipment, resulting in economic losses, while corrosion
The object can be transferred into the water to pollute water quality, and thus the scaling on the heating surface is promoted, and the scaling and corrosion are promoted, resulting in a vicious circle of corrosion and scaling.
(3) prevent the accumulation of salt. In boiler water impurities and excess salt, brought out with the vapor deposition in the superheater and steam turbine, this phenomenon is called salt, salt accumulation in the superheater can cause overheating of metal wall or even burst; steam turbine inner product salt will reduce output and efficiency
