Dry coke quenching auxiliary boiler

The domestic-first developed new type of water preheater for dry coke quenching, namely the dry coke quenching auxiliary boiler, uses a serpentine pipe structure for the internal piping. The extended heating surface adopts an H-shaped fin structure. At the same time, it utilizes the method of heating the feed water by the return water, which increases the inlet water temperature of the auxiliary boiler and prevents corrosion issues.
