Although Ringelmann Blackness is very simple to use, you should also pay attention to some points, which can not only make the detection data more accurate but also extend the service life of the product
Illumination light during observation (i.e. direct sunlight) Light or illumination from the sky) should be side light, approximately at right angles to the line of sight, and front light and backlight should be avoided
In foggy conditions, due to the dark sky background, a slightly lower level should be remembered when reading< br/> There should be no dark obstacles such as mountains, trees and buildings on the background of the chimney outlet. When observed, it should represent the normal operating status of the boiler. The boiler load is required to be kept above the rated load. At this time, no water should be added to the coal, and no excessive amount should be added. The measurement of blast balance
cannot be accurate once, each interval can be controlled within a minute, and the data are recorded sequentially (the instantaneous blackness of each observation, such as the blackness of smoke and dust is between two levels, can be estimated to / level blackness value, and finally average the measured values, which is the blackness of the smoke.
I believe that as long as you follow the above steps and pay attention to the precautions, you will be able to operate this product with ease.
