types of boiler in thermal power plant

At present, high pressure hydraulic descaling is still limited to industrial types of boiler in thermal power plants with simple structure. The role of boiler alkali cooking is mainly to transform the scale, and at the same time to promote its loosening and shedding. Pure alkaline cooking has a poor effect on scale removal, and it often needs to be carried out with mechanical descaling. The scale removal by alkali cooking has certain effect on the scale mainly composed of sulfate and silicate, but it is not as good as acid washing for carbonate scale. Alkaline scrubbing furnaces are also often used for rust and oil removal of newly installed boilers, and sometimes for oil cleaning or scale conversion before pickling.

Improvement: condensing types of boiler in thermal power plant after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled concentration of total iron ions. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation.
