"Hard water" refers to water that contains more, soluble, calcium and magnesium compounds. Whether buying a
Hot Water Boiler or a
Steam Boiler, the water entering the boiler must be water-treated soft water.
Why is the boiler's water requirement so high?
Ordinary water is put into the boiler, and it is very easy to scale. Because the steam is continuously evaporated, the concentration of calcium, magnesium and impurities in the boiler water will be very high, which is 30-50 times that of natural water. There can be 1-2mm scaling. The scale damage greatly threatens the safety of the boiler, and in severe cases, it can cause the boiler to burst!
After the scale appears, the thermal conductivity is only less than 0.5% of that of the metal. After the boiler scale appears, if you want to achieve the thermal efficiency without scale, you can only increase the temperature of the heating surface inside the boiler. For example: when the furnace wall temperature is 250 ℃, When 1mm of fouling occurs, to achieve the same thermal efficiency, the wall temperature must be increased to 650°C. At this time, the heat absorption rate is extremely low, the energy consumption is increased, and the fuel cost is doubled.
It can be seen that, no matter from the point of view of safety or economy, boiler water must be used in accordance with the usage specifications and can only be used after water treatment.
