Analysis on Anti-Corrosion Technology of New Dual-Plate Air Preheaters
Unlike ordinary plate air preheater, the new dual-plate air preheater can generate temperature gradient through adding another plate in cold side to maintain certain space. And it can decrease the temperature of hot fluid in the outlet while increasing the temperature of plate surface to achieve the purpose of anti-corrosion.
