1.Black dirt or soot, especially such dirt clinging to or ingrained in a surface.
2.The results show that a controlled blasting method by charging onout wall of pipe with the mixed RDX and TNT-NH 4NO 3 can effectively descale ash carrier pipe.
3.A Study of Scale Inhibition and Prevention for a Thermal Power Plant Wet ash Transportation
5.Study on Dynamic State Scale Simulation of Wet Ash Transportation System in Power Plant
6.Improvement on Method for Determination of CO 2- 3 in Ash Conveying Pipe Scale
8.The dissolving kinetics of free CaO in water and the aerating kinetics of ash-water were studied. And on the basis of that, the feasibility of treating high pH value ash water by being exposed to weather, and the feasibility of nature aerate-scale inhibitor technology were discussed.
9.A combined method was proposed i.e., to separate circulating water from washing ash-water and form closed circulating, make acid dipping of condenser copper pipe, add scale and corrosion inhibitor, and perform sterilization and filtration.
