Description

Technical Field

[0001] The utility model belongs to the technical field of boilers, and particularly relates to a device for comparing the scale formation ratios of different water qualities for boiler scale research. Background Art

[0002] After long-term use, a boiler is prone to generate a certain amount of scale inside it. The scale may cause the metal wall temperature of the boiler to rise sharply, exceeding the temperature that the metal can withstand, thereby triggering safety accidents and shortening the service life of the boiler; moreover, scale formation in the boiler will cause under-scale corrosion, reducing the effective thickness of the metal, and the scale that is difficult to remove will accelerate the aging and damage of the boiler. At the same time, there is also a situation of economic waste, that is, in addition to increasing fuel consumption, the scale will also increase the time, cost and workload of cleaning and maintenance, causing an additional economic burden.

[0003] In order to facilitate the removal of scale using chemical reagents, it is necessary to study the differences in the scale generated by different water qualities, that is, to collect and compare the scale on the inner wall of the boiler working under different water qualities. The existing scale is generally collected by staff inside the boiler. This collection method is relatively complex, and when collecting and transporting multiple types of scale, it is easy for the scale to deteriorate and be damaged, resulting in errors in the final experimental results.
