what causes airlock in hot water boilers

The sum of the concentrations of Ca2 and Mg2 in water is called the hardness of water. It is clearly stipulated in the regulation of boiler supervision that the hardness of boiler water is ≤ 0.03mmol/L.Ca2 and the Mg2 is distributed in water in the form of ions, even if the water is softened, there are still some sulfate ion and bicarbonate ion in the water. Because bicarbonate ions are always dissociated in water, i.e.: HCO3-A→H++CO32-(1). Although the dissociation is very weak in this process, the dissociation is strengthened due to the (2), (3) reaction. Then, in boiler operation, there are always conditions for the formation of insoluble substances: Ca2++CO32--CaCO3(2). Mg2++CO32-→MgCO3+(3)

Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired boilers, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation.

It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.

Solutions: The PH of boiler water should be adjusted in order to reduce the probability of boiler scaling and corrosion. In general, the PH value of boiler water should be kept between 10 and 12. If the hardness of boiler water is too large, it should be properly supplemented with soda to increase its PH value to a suitable range;

Boiler what causes airlock in hot water boilers-depth study of aspects of the in-depth study of hot water boiler feed water parameters and other aspects of the hot water boiler feed water and parameters like, for this kind of boiler, the following will explain and answer some questions in order to advance their learning process.

Boiler parameters, if it is for the hot water boiler, then, specifically what? Steam boiler difference? Boiler parameters, which if it is for the hot water boiler, then specifically, for the thermal power, water pressure and supply and return water temperature three. For steam boiler, the amount of steam that is, the operating pressure and the steam temperature three. So, these two boilers in the boiler parameters, is not the same, can not be equated. Rated temperature hot water boiler, which specifically refer to? Notes on the boiler, which prevent matters?

In the boiler, a small amount of replenishment is inevitable, however, to note that, should strictly control the quality of supply water, deoxygenated water is recommended, because it can avoid fouling, or scale issues such as boilers. And this is for the normal operation of the boiler, is also useful.
