  Heavy Duty Coating | NOROO Paint & Coatings

  ① Temperature: The coating temperature range suitable for all paints is between 5℃ and 40℃. ② Humidity: For all paints, the surface temperature of the substrate should be more than 3℃ above the dew point. Note that painting below 3℃ may cause the condensation of water on the surface of the substrate, which may reduce adhesion.

  Results show that the acid dew point of flue gas at mill outlet is sensitive to the desulfurization and dehydration process under recirculation mode; when high sulphur coal is burned, serious lowtemperature corrosion will occur in the mill; the acid dew point of flue gas decreases with the reduction of boiler load, which is determined by both ...

  Corrosion-Resistant Coatings for the Offshore

  They have no dew-point restrictions, and can even be applied in temperatures as low as -15°C. Many major painting projects are delayed by unforgiving application restrictions of typical epoxy, urethane or inorganic coating. MCU-Coatings removes these restrictions and still yields better corrosion .

  Environmental Assessment of Coal Transportation

  The consensus is that combustion is good but that heat losses are large because of water evaporation and loss of sensible heat. Another difficulty in firing of fuel with high moisture content is the potential that the temperature of the mixture could drop below the acid dew point. This could cause significant corrosion.

  prevent acid corrosion and fouling. The acid dew point of flue gas has been studied in the literature, and many prediction formulas of acid dew point have been put forward [27–31], which indicate the acid dew point is mainly affected by the sulfur content in coal, the volume fraction of SO3 and water

  Improving Boiler Efficiency - Chemical Engineering Site

  Oct 29, 2016· So the temperature profile across the boiler sections is to be compared with the design and if wide deviations persist, shutdown is to be taken for cleaning to improve heat transfer. The limitation in decreasing the stack temperature is the cold end corrosion due to sulfur dew point.
