The application of BD7053 desulfurization absorption tower and slurry pipeline special anti abrasion corrosion resistant protective coating:
The flue gas damper door,it's mainly corrosion based on the place where contacts with the net flue gas,together with the abrasion,the combined coatings choose BD407 corrosion resistant special coating,BD408 high temperature flakes anti corrosion wear resistant coatings,BD7053 desulfurization absorption tower and slurry pipeline special anti corrosion abrasion resistant coating.It's mainly the abrasion based on the place where contacts with the original flue gas,the combined coating chooses BD427 high temperature corrosion resistant coatings and BD776 high temperature impact resistant silicon carbide coatings.
The flue gas heat exchanger (GGH),is the heat transfer site of boiler flue gas and desulfurization flue gas,corrosion and abrasion exist side by side, the combined protective coatings choose the BD427 high temperature corrosion resistant coating and BD776 high temperature impact resistant silicon carbide coating,this place chooses BD776 not only for the application of its wear resistant performance,but also for its good thermal conductivity,the thermal conductivity is 1.4 W/M K, this composite coating is wear resistant,corrosion resistant and heat conduction.
