Why can't the boiler use "hard water"?

Hard water is a common name in our lives, refers to water containing calcium and magnesium ions and other impurities. In life, the use of this kind of water is more, it is easy to accumulate scale; and the same is true in boiler equipment.

Boiler water generally contains impurities, mainly calcium and magnesium salts. If the hardness is above 8 degrees, then it is called hard water, and when it is used, it is easy to form hard scale in the boiler, which will increase the energy consumption of the boiler. To solve and avoid scale problems in boilers, it is necessary to start from the source and soften the hard water.

A boiler of 1 million kcal is equivalent to a boiler of 1.7 tons. Because 600,000 kcal is equal to 1 ton, it is only possible to draw a conclusion.

When it is found that the boiler's hot water supply pipe is frozen, the solution measures are mainly the following aspects.

Measure one: The boiler operates at a low temperature, and its temperature is gradually increased to defrost naturally.

Measure 2: Use fire welding, or use liquefied gas for fire roasting.

Measure 3: Use electric heating or hot water pouring to defrost.

The energy used by the gas-fired boiler is gas fuel, which is a kind of clean energy. Therefore, the flue gas generated by the boiler does not require special treatment. The feed water is also softened water, and it only needs to cool down and settle during the sewage discharge, and the operation is very simple.
